C55 Two Knights: 4.d3, 4.d4 exd4 5.e5 and Max Lange Attack (7 moves of theory)

C55 Two Knights: 4.d3, 4.d4 exd4 5.e5 and Max Lange Attack (7 moves of theory)

This game was originally shared in the post C50 Italian Game: Hungarian Defense. That post has been renamed to C55 Two Knights: 4.d3, 4.d4 exd4 5.e5 and Max Lange Attack (8...Bf6). The info about the team match is out of date since it was typed when I orginally shared the game. This game is taken from a team match called Art of Chess vs VIP ChessQueen. It was played between Art of Chess and VIP Paul Morphy Chess on 46 boards. I played board 5 for VIP CHESS and won both my games on time. During the same day, February 19th 2015, I won four games against this same opponent on time. It is always annoying to win these correspondence games on time as the games seem really unfinished, especially when the situation on the board does not correspond with the result. The match ended with a score 58 - 34 in favor of the home team Art of Chess. This match started December 1st 2014, finished on April 29th, 2015 and players who signed up for the match had to be rated under 2000.

This game followed the first game in the post C55 Two Knights: 4.d3, 4.d4 exd4 5.e5 and Max Lange Attack (8...Bf6) only up to the move 3...Be7. In that first game leduar played 4.c3. In this game JogadorAmador played 4.d3. There is nothing really wrong with either move, but 4.d3 is slightly better. The first position of interest can be seen below. In that position I chose to play the move 11...Bd6. It was a bad move after which I was clearly worse or at least quite close to it.

A few moves later I made an even clearer mistake by playing 15...g6 in the position below. The game continued with the moves 16.Bh6 Rfe8 17.Ng5. Then I made the worst move of the game so far, 17...Nd8?? After that I should have been in a lost position. However, there was only one move that could have taken the winning advantage and that move was 18.f4. JogadorAmador played 18.a4 instead and I was let off the hook a bit.

JogadorAmador's 18th move did keep the advantage in side of my opponent and that did not change during the remainder of the game. I only won because my opponent did not make his 23rd move and lost on time.

Game number two. This game was played in the "atadros's mini-tournament V". 11 players participated in this mini-tournament and I was 9th in the final standings. I was only able to gather 5.5 points in 20 games, so this was really bad mini-tournament from my point of view. In this game I faced atadros, the player who created this mini-tournament. Atadros was on 4th place in the final standings and my opponent was able to gather 13.5 points. The mini-tournament was won by a player called desaparicidos (2080). The winner gathered 17.5 points out of the possible 20 points.

The same moves were seen in this game as they were seen in the first game in this post up to the move 7...Bg4. Only the move order was slightly different. The move order was the same only up to the move 3...Be7, but when in game two the move order was 4.d3 Nf6 5.Nbd2 O-O 6.c3 d5 7.Bb3 Bg4, in this game the move order was 4.c3 Nf6 5.d3 O-O 6.Bb3 d5 7.Nbd2 Bg4. In the first game JogadorAmador played 8.O-O and in this newer game atadros chose to play 8.Qe2. It is not really an improvement to the older move, actually it might be somewhat worse. However, there is no significant difference between the two, so 8.Qe2 is also a decent move. Atadros was the first one to make a mistake in this game. It was a bad idea for my opponent to castle long in the position below.

My reply, 13...a6, was designed to protect the advance of my b-pawn. It was a bit slow plan and it was a better idea to move my knight to a5. It is according to Stockfish 8 64 POPCNT Black's best move against 13.O-O-O and the only move that would have given me a clear advantage. The move I played in the game did not give me much. A few moves later atadros made a huge blunder that could have lost the game. In the position below atadros played 18.g5??

I had the possible line to victory in my grasp, but I let it go, because I could not see the continuation starting from 18...bxc3. I played the inaccurate move 18...hxg5 instead and my opponent was back in the game again. Atadros replied by taking the pawn on g5 with the knight and the position was about even. Then I blundered and played 19...Qc8, after which it was my turn to be on the losing side of the board. For some reason my opponent played 20.Rc1 instead of the obvious looking and winning move 20.Qc4. After both players had missed their chance to get a winning advantage, the game continued quite evenly until it was my turn to get the winning advantage again in the position below. Atadros made a huge mistake by playing 24.Ng3??

I was able to find the best move 24...Bxc3 and things looked to be going my way again. Unfortunately for me, I was not able to play accurately all the way to the end and when we reached the position below, I threw my advantage away with the move 28...Nxf3. Even after my sloppy move 28...Nxf3, I should be slightly favored, but it would be unlikely that I would actually win the game.

Only a couple of moves later I made the game losing blunder when I played 30...Qe7 in the next position. In order to keep my small advantage, I should have played 30...c5. It was perhaps my best chance to keep me on the better side of the board.

Atadros answered with the move 31.Rg1 and no matter what I do, I should be quite lost. I did my best to prevent the inevitable defeat, but I accepted my loss in the position after 37.Ka3 and resigned.

C41 Philidor Defence (8.c3)

C41 Philidor Defence (8.c3)

This game was previously found in the post C41 Philidor Defense: Larsen Variation. That post was renamed to C41 Philidor Defence (5...Bg7), in order to be consistent with the way I am currently naming my posts. This game was played in the "paweljaniak's mini-tournament I". This was probably the best mini-tournament I have played at GameKnot. I was second in the final standings and I gathered 8.5 points in 12 games. Well, I actually only played 11 games since one of my opponents withdrew from the tournament. It was the only game that was never played. My opponent in this game, chief_huerta, finished 7th in this mini-tournament and was able to gather 2.5 points in 12 games.

This game followed the first game I shared in the post C41 Philidor Defence (6...Nc6) up to the move 6.O-O. In that game a player called veca played 6...Nc6, while chief_huerta played 6...Ne7 in this game. I think the first turning point of the game came when chief_huerta played 13...cxd5 in the position below.

I responded with 14.exd5 and according to Stockfish 8 64 POPCNT I should have been clearly better. Chief_huerta replied with e5 and I continued with 15.Ne4, which threw away some of my advantage. The best move was 15.Bxe7. Then my opponent played the huge blunder 15...Rf8 and it could have been the losing move. I did not continue with the most accurate moves, but it was only after my 33rd move Qf3 that all my advantage had disappeared. The next position is where I played 33.Qf3.

Chief_huerta played 33...Qe6 in reply and I continued by playing 34.Bd2. Then chief_huerta played 34...Be7 and I was clearly better again. When we reached the position after 35...Nf6, which you can see below, I moved my knight to the wrong square and it allowed my opponent to get back into the game again.

Chief_huerta then took another step in the wrong direction with the move 36...Nh7. It was the start of the final downhill for my opponent. The remainder of the game went clearly in my favor and chief_huerta resigned after my 50th move a4.

C41 Philidor Defence (6...Nc6)

C41 Philidor Defence (6...Nc6)

It seems that only one of my opponents has favored this line. I can't say that for certain yet, as I have so many games still to go through, but so far it is the case. The game below was played on the first round of the 2014 October Long Haul Split I tournament that is played at Red Hot Pawn. The tournament started with 24 players and they were divided into two groups of 12. Group 1 was won by caissad4, who was clearly the highest rated player of that group. Caissad4 managed to get 59 points out of the possible 66. I won group 2 with the same amount of points as caissad4 and we played on round 2. I thought that the second round would be very evenly fought before it started because the rating difference between these two players was not that great. That being said, caissad4 was higher rated than me at the time and has a peak rating much higher than me at Red Hot Pawn. By considering only the ratings, caissad4 was the favorite on the second round. If the results of our 9 completed games before round was considered, then I was the favorite on the second round because I had won 5, drawn 3 and lost 1 out of those games. The second round ended in a tie between us two, so third round was needed to decide the winner of the tournament. On the third round I got a draw and a loss against caissad4 and therefore caissad4 won the tournament and I had to accept my second place.

This game followed a few games previously shared in this blog up to the move 5...Bg7, but then it followed a different move order, but reached the same position as was seen in the first game in the post C41 Philidor Defence (5...Bg7) after the move 8.Be3. It was the last same position seen and the games went on a completely different path from Black's 8th move on. In the first game the move order after 5...Bg7 was as follows 6.c3 Ne7 7.O-O Nbc6 8.Be3. In this game the move order was 6.O-O Nc6 7.c3 Nge7 8.Be3. The game started to go seriously downhill for veca when my opponent played 15...b5 in the position below.

I replied to the move played in the game with 16.Qe2, which was an okay move, but not as good as 16.axb5 which was the best reply. Veca then played 16...Ne7 and then I let my opponent off the hook with the move 17.axb5. I should have played 17.Nxe7+ instead. The position after my 17th move can be seen below.

It was in this position that the game deciding blunder was seen. Veca played the awful move 17...axb5, which lost a piece because of the continuation 18.Rxa8 Qxa8 19.Nxe7+. The game was easy after I got the decisive material advantage. The game ended in checkmate when I played 60.Qa1#.

C41 Philidor Defence (7...Qe7)

C41 Philidor Defence (7...Qe7)

The things typed after this sentence were typed when I originally shared this game. This was played at ChessRex.com. This was a correspondence game and both players were able to use 7 days for each move. The interesting thing is, I had faced the position after 10.Bd2 in a game I had played a couple of months before this game in a team match that was played over the board. Not only that but I also faced the same position in another game at ChessRex.com. In all three games the move order was exactly the same. When I reached the position after 7...Qe7, I was annoyed that I had not analysed the over the board game because I had thought about two moves here, 8.Qxb7 and 8.Bxf7+. Despite having thought about those possibilities, I did play 8.Qxb7 in all three games though I did consider Bxf7+ maybe better, but I was not confident enough to play it, mostly due to the fact that I do not trust my calculation skills. I did check those possibilities with Stockfish 6 64 BMI2 now and it first thought that Bxf7+ is better, but after some time it decided that Qxb7 is clearly the better move. Like I have previously typed, the move 6...Nf6 is the losing move of the game. The rating shown in the notation is my current rating there after two games. That is also the only rating you get there, it does not matter if you play chess, chess960 or the times you are using for the game, the rating is still the same. It is the only site where I have played that uses only one rating for players. It is certainly something that makes it stand out from other sites. The first time I noticed only one rating for players, I had to ask about the rating thing in the lobby, because I could not believe it. I actually embrace these different ways to do things, it is refreshing to me.

Game number two. This game had a very similar start as the previous game in this post. I was rather surprised of that fact, but also because these two games followed a game I had played in a over the board team match couple of months before these two games started. These two games that were played at ChessRex were quite easy because of that earlier thought process I had done during that team match. Of course all these games did deviate from each other at some point, but I think it was this second game that followed more closely to the over the board game.

B00 Queen's Fianchetto Defence, Nimzowitsch Defence (6...Ne7)

B00 Queen's Fianchetto Defence, Nimzowitsch Defence (6...Ne7)

I may need to think about the way I name I posts again because the stuff I put between () signs may not be accurate to all games that end up in the post due to move order. The only reason I put anything there at all is that I need to differentiate between games that follow theory different amount of moves, but the name of the opening played in the game would still be the same. Maybe I should have put all the games featuring the B00 Queen's Fianchetto Defence, Nimzowitsch Defence, for instance, in the same post and then only typed about the theoretical difference of the games, but somehow I still prefer the way I do these posts now.

The game below was played in a team match called The Simpsons New Match. It was played on 50 boards between "SIMPSONS" and Chess Champ. I played on board 7 for Chess Champ and I was able to win both of my games against Ruferto1944. I think this game was the last one to finish in this match, it was not the first time that my game was the last one to end and it most likely will not be the last time, considering how much time I use for each move, most of it does not go into the actual thinking of one particular position, but instead many positions at the same time need solving. And I need to sleep at some point too... My time per move is 1 day and 20 hours currently at Chess.com, so I have made my moves a bit quicker on average than in the past when the time I use per move was over 2 days on average. My hastened moves have also reflected negatively on my rating because it just keeps going steadily down. It is not the only reason for it, but it is a major contributor to the results.

The move 3...Bg4 I have seen quite a few times and this was the second time that I chose to play 4.Be2 in response. In the first game to feature the position after 4.Be2 Arayn played 4...h5. Ruferto1944 played 4...Nf6 in this game, which is obviously a better alternative. Ruferto1944 made some inaccuracies, which when added together, resulted in a clear advantage for me when my opponent played 9...Qd7 in the position below.

The game continued with the moves 10.Bg5 Bg7. Then I played 11.Be2, which gave some of my advantage away. With his 12th move Ruferto1944 took another wrong path. My opponent played 12...a6 in the position below. In reply I played 13.Qg3, throwing some of my advantage away once again.

The game continued with mistakes done by both players and shifted quite a lot until we reached the position you can see below. I was on only slightly better side of the board, but because Ruferto1944 played 29...Ne3, I had another chance to get a clear advantage.

I was accurate enough to not only get a clear advantage, but also prevent my opponent to get back into the game. Then on his 34th move Ruferto1944 made the blunder that quickly ended the game because 34...Kh6 allowed a mate in two moves.

C44 Ponziani Opening and Scotch Gambit (5.cxd4)

C44 Ponziani Opening and Scotch Gambit (5.cxd4)

I did update the tournament info to reflect the current situation and round one is still in progress. Soon it will be three year anniversary for round one... This game was played on round one of the 2014 September Glacial Super Casual I tournament that is held at Red Hot Pawn. There were 64 players who started this tournament and they were divided into groups of 8 players. I am playing in group 7 and I currently lead the group, having only lost one game so far. I have only one game left to finish on round one and I feel confident about my chances to win the group. And I should win it, being the clearly highest rated player in the group. It has been the case since the start of the tournament even though my rating has plummeted again. There is still one player who can take the win out of my grasp. I have gathered 36 points so far, a player who is currently second, Timothy Collins (1663), has gathered 30 points and third place went to dooser2004 (1678), who gathered 23 points. Timothy Collins is the only person in the group who can still take the win from me and my only game in progress is against him. A couple of other games are still in progress, so it is not only my game that is delaying the tournament.

In this game my opponent tried the move 3...Nc6, something that no opponent of mine has played before in the games previously seen in this blog. It might be the best try of my opponents so far. That being said, it is not a move that could be recommended. My opponent, Chippy Minton, was able to maintain a rather decent position against me until it came time to reply to my 9th move O-O. The position can be seen below.

Chippy Minton played 9...Bxc3. It was a mistake to give up the bishop pair without any provocation. A better alternative for my opponent would have been 9...O-O. I maintained the advantage quite easily, but it was only due to my opponent's huge blunder on move 15 that I was able to finish the game with the move 16.Qh7#. Otherwise the game could have continued a lot longer.

C41 Philidor Defence (4.Be2)

C41 Philidor Defence (4.Be2)

The tournament info is a bit out of date, since it was typed when I originally shared this game. I could have updated it to the current situation, but I decided not to do that. This game is from the 2014 August Grand Seven Fourteen III tournament that started August 11th 2014. As there were no rating restrictions to join this tournament, the lowest rated player is rated 922 and the highest is rated 2065. Seven players are under 1400, there are ten players between 1400 and 1700 and the rest three are between 1827 and 1913. When I look at the tournament results so far, it would be interesting to see that I fight for the third place against the currently fourth lowest rated player in the tournament if I was not aware that he had a much better rating when he played these games. Well, enough that he managed to get 97 points, I think he may have lost some games on time as most of his latest games have been lost on time. I have currently the third highest rating in the tournament, 1861, so I am quite close where I ought to be considering the rating situation.

I have faced the move 3...Bg4 quite a few times. I should have, of course, continued like I had done before and play 4.dxe5. For some reason I decided to play 4.Be2 in this game. 4.Be2 is not a bad move by any means, but I think I prefer 4.dxe5 and the positions that might arise after it. The reply to 4.Be2 was 4...h5, which was the starting point for my opponent's downfall. Arayn should have played 4...Nf6 to stay in the game. I was not always able to find the strongest moves, but I was able to keep the advantage on my side to the rest of the game and even increase my advantage. The game ended in mate on move 33.

C41 Philidor Defence (3...f6)

C41 Philidor Defence (3...f6)

This game was played in a tournament called 2014 September Grand Seven Fourteen III and it is held at Red Hot Pawn. In this 21 player tournament there are still seven players that can win it and I am one of the lucky ones still included in the fight for the win. There is unfortunately large rating scale in this tournament as the lowest rated player is rated 881 at the moment and the highest rated player is rated 1938. Well, even if there is a huge rating difference between these two players, it does not mean that this tournament would be clear as to who wins and who will hold the last place at the end of the tournament. That is because there are also players close their rating who can make things more interesting. The game below is just one example of those huge rating differences in this tournament that are unfortunately occuring. I don't think games where there is this huge rating gap between players is all that beneficial to either player. Then again, accidents do happen and I think I lost to a player who was rated 800 or so points lower rated than me because I missed the mate in one threat he did...

This game deviated from the games that I have previously seen in my games when my opponent played 3...f6. The other two tries in that position were in the previous games 3...h6 and 3...Bg4. The latter option is better than 3...h6 or the move jayvi tried in this game, 3...f6, but the best option for Black might be 3...exd4. The third move of my opponent already gave me a clear advantage. In the position below my opponent played 4...Ne7, which could have been the losing move.

I replied with the inccurate move 5.O-O and while it was not the best move, I still remained on the clearly better side of the board. The best reply was 5.dxe5. Jayvi's position continued to go downhill with the move 5...d5, after which the game is quite lost for my opponent. The game did not last long after this and my opponent resigned after my 10th move Nd4.

C41 Philidor Defence (1.e4 e5 2.Nf3 d6 3.d4 Bg4 4.dxe5 Bxf3 5.Qxf3 dxe5 6.Bc4 Nf6 7.Qb3)

This game was played at Red Hot Pawn in a tournament called 2014 August Grand Seven Fourteen II. The tournament is all versus all 21 player tournament and you play two games against everyone else and all games are played simultaneously. I am currently the second highest rated player in the tournament and I am also currently second in the standings and some small hope is left for me to win the tournament.

It seems that I had found the move 7.Qb3 already in this game, but I had not played it in some of the games that started later than this game. While it did not change the result, it is still important to play the best moves if possible. I was basically in a winning position after 7.Qb3 and remained in a winning position the remainder of the game. However, while I had a possibility to end the game in the position below, I was unable to do so.

I missed the mate in one, 20.Qd5#, which is somewhat embarrassing. I continued playing a bit sloppy chess, but finally I was able to find the mate and end the game on move 27. A correction to the post was made September 27th, 2017. I noticed that the first game and the second game did not have exactly the same opening, one move was different and I only noticed it today, I am sorry about my mistake.

C41 Philidor Defence (6...Nf6)

C41 Philidor Defence (6...Nf6)

This game was played in a team match called Diamonds vs Space Angels---Open 3day/move, 1-10 boards. The match was played between Diamond Members & Staff and Space Angels Miami Beach Pier Walkabout in Andromeda's Cluster Of Infinite Bright Stars. The latter team name changes almost every time I see it... Only the Space Angel and the last part starting with Andromeda's is consistent on the team name. This was played on eight boards and I was playing board 4 for the Diamond Members & Staff. The match ended in our victory 11 - 5! I managed to win both my games.

The game might have started to go a bit wrong for my opponent with the move 3...Bg4, but the fourth move by Egoigwe gave me a clear advantage. The position below has been taken after my 6th move Bc4. I have reached this same position a few times since this game was played and in those games I have been mainly able to find the best reply to 6...Nf6, the move my opponent played in this game.

When this game was played, I did not find the move 7.Qb3 and instead played 7.O-O. While I remain on the better side of the board even after 7.O-O, I would have been close to a winning position after 7.Qb3. I was able to keep the advantage clearly on my side and even increase my advantage along the way, thanks to the bad moves by my opponent and sometimes accurate moves that I made.

C07 French Tarrasch: 3...c5, 4.Ngf3 and 4.exd5 Qxd5 (6.Qxd4)

C07 French Tarrasch: 3...c5, 4.Ngf3 and 4.exd5 Qxd5 (6.Qxd4)

This game was played in a team match called Chess Match Championship 1200+. The match was played on 76 boards between Chess lovers & CHESScom-International_EUROPE and Kopaonik. I played on board 18 for Kopaonik and I was able to win both of my games against chesszardoz. The final result of the match was 67 - 85 in favor of Kopaonik! While it was nice to be on the side of the winners, not all aspects of the match are so nice. The reason for it is that there were a lot of players in the match that have their accounts closed due to violation of the fair play policy. There were 9 of those in our opponent's roster. We were unable to avoid this thing and one player in our roster also has the Closed: Fair Play badge next to the username.

This game deviated from a previously shared game in this blog, in the post C07 French Tarrasch: 3...c5, 4.Ngf3 and 4.exd5 Qxd5 (7...Qd8) when I played 5.Ndf3. In that game my opponent played 5.dxc5. Both moves lead to a game that is evenly fought. No clear advantage was seen in the game until chesszardoz played 27...Ke8. I did get to the wrong side of the board with the move 13.Bb5 and I was slightly worse for awhile, but I was able to stay in the game long enough to my opponent play his 27th move in the position below.

The best and actually the only move that would have kept my opponent on an equal footing was 27...Bd5. Other moves were the source of serious trouble for my opponent. Actually the move chesszardoz played was the second best move in the position. I replied with the obvious and accurate move 28.Nf5. Then my opponent played 28...Rd7 and after that I allowed my opponent back into the game again with the move 29.Nxh6. The advantage shifted a bit back and forth and the last time my opponent threw away the game was in the position below after my 30th move, Nf5.

Chesszardoz should have played 30...Bc5, but instead he went for the move 30...Bf8. The rest of the game went in my favor, but I missed an easy win in the position below. During the game I could not think of a better move than 50.b3, but obviously I should have played 50.Rxb5!

Taking the pawn on b5 would have forced the trade of rooks, which would have made my job of winning the game a lot easier than it was in the game continuation.

C01 French: Exchange Variation (7.Nge2)

C01 French: Exchange Variation (7.Nge2)

This game was played in the "atadros's mini-tournament V". I was 9th in the final standings of the mini-tournament with 5.5 points. Considering that I played 20 games, the amount of points I gathered is not impressive. My opponent in this game, negotium, was 5th in the final standings with 11 points.

I have seen the move 5...h6 previously played, but in this game negotium played 5...Be7. Both moves should be playable, one is not significantly better or worse than the other. While this game ended in a draw, it did have points at which one of the players could have directed the game towards a win. Probably the first clear mistake was played by me in the position below in which I played 33.Bb1.

The correct move was 33.Qe2. After my 33rd move, negotium could have taken a clear advantage, starting with the move 33...Rd8. In the game negotium played the less accurate move 33...Qf4, which let me off the hook a bit. I played another bad move in reply, 34.Rc4. After that I was clearly worse once again. 34.Rd1 was a better option. My opponent's advantage did not last long, already in the position below where negotium played 35...Qf6, the advantage had disappeared.

The game was fought quite evenly until I blundered with the move 40.Kh1 in the position below. Negotium found the strongest reply 40...Rd8 and I was clearly worse. Then I played 41.h3 and I was in a losing position or at least very close to one.

41.h4 was probably a better move, but I would have been in trouble regardless. Negotium replied to 41.h3 with the move 41...Nd3 and I was back in the game again. I was able to hold the position equal for the rest of the game and draw was agreed upon after 47...Qa1+.

C01 French: Exchange Variation (5.Bg5)

C01 French: Exchange Variation (5.Bg5)

Previously one of my opponents has played the move 4.Nf3 and I have played the move 4.Be2. Even though the game where I played the move 4.Be2 was successful for me, I chose to play 4.Bd3 in this game. All of the three options are perfectly playable and none of them actually decided the game. The game was played quite well by both players until I took my first step towards the loss in the position below.

I played 13.dxc5 and ended up in some small trouble. In order to keep the position equal, I should have played 13.Na3, 13.Bb5 or 13.Rc1. The game continued with the following moves 13...bxc5 14.Na3 Ne5. In that position I moved my bishop to f5, which was my second unfortunate step towards the loss. Foogie1 played 15...Bxf5 and had a clear advantage. Foogie1's pieces were all well placed, maybe apart from the rook on a8. My knight on a3 was placed badly, it could not easily get into the game. Also my pawn on b2 was rather weak and easily attackable. While my position was rather difficult, it was not lost until I played 17.Qg3 in the position below.

Instead of 17.Qg3, I should have played 17.Qd6, but even there, the position does not look promising for me. I played a few more moves, but had to accept my defeat after the move 23...Nfh3+.

C01 French: Exchange Variation (7.Bg5)

C01 French: Exchange Variation (7.Bg5)

Continuing the changes with my previously shared games and after they have all been changed, new chess games will appear. This will take a long time, unfortunately. This game was played in a team match called Match Name: TMCL 2016 Sub-Div. B4 R3. It was played on 203 boards between I like beer and Chess and Baker Street Irregulars. I played on board 19 for Baker Street Irregulars and in addition to this win, I lost my other game against jtibon. The final score in the match is 190.5 - 215.5 in favor of Baker Street Irregulars.

I have played this way with black up to the move 3...exd5 and one of my opponents continued with the move 4.Nf3. In this game I was controlling the white pieces and I chose to play 4.Be2. Both moves should be good enough to play in the future, but I would prefer to play 4.Nf3 in the future. I ended up on the slightly worse side of the board already with the move 11.Ng4, but it was on the position below that the game started to steer away from the draw that would have been likely, had the game been played accurately to the end. I played 19.f4, which could have cost me the game, had my opponent replied with 19...Re3.

Jtibon played 19...Be4 instead and the position was slightly better for me after the reply 20.Ng3. My opponent blundered a second time in a row and played 20...c5?? Jtibon's 20th move turned out to be the mistake that cost my opponent the game. The rest of the game was just a matter of technique.

B83 Sicilian Scheveningen 6.Be2, lines without ...a6 (9.Qd2)

B83 Sicilian Scheveningen 6.Be2, lines without ...a6 (9.Qd2)

This was previously shared in the post B83 Sicilian Defense: Scheveningen Variation, Modern Variation #3. The remainder of the post is taken from the original post, with the exception of the diagrams and the name of the opening has been added to the game, the original classification of the opening can also be seen in the game. This game was played in the atadros's mini-tournament V at GameKnot. The mini-tournament consisted of 11 players and I was 9th in the final standings with 5.5 points, so things did not go all that well in the 20 games I played in this mini-tournament. My opponent, rayfisher, only managed to get one point, from the two draws he managed to get and he was on last place in the final standings. The mini-tournament was won by a player called desaparicidos (2080). The winner was able to gather 17.5 points, which consisted of 17 wins and 1 draw. I, on the other hand, won 2 games and played 7 draws, which is a very rare thing for me.

I have seen the move 8...Bd7 played against me before, but in this game rayfisher went for the move 8...O-O. Out of the two moves 8...O-O might be the more accurate one. The first critical error came in the position below when my opponent played 13...b5. Rayfisher's 13th move was a really bad one and it could have lost the game.

I honestly do not know what I was thinking about when I replied to rayfisher's 13th move, because I played 14.a4 instead of the obvious 14.Nxb5. I messed up my winning chance and ended up in a position that was roughly even. My next chance to take the game firmly in my grasp came after my opponent played 21...Bxd5 in the position below. In order to stay in the game rayfisher's only chance was to play 21...exd5. I had maybe three good moves to play in reply, 22.Qg4, 22.c4 and 22.Qg3 but I did not play any of them. All of those three moves would have been good enough to take the winning advantage. I played the move 22.Bd4 and gave my opponent another chance to hold on.

Rayfisher then played 22...Qc7, which was a mistake and with a correct reply I could have been on the clearly better side of the board. 22...dxe5 and 22...a5 were better alternatives for rayfisher. I was not able to find the best move, so I threw the advantage away again with the move 23.Bd3. Rayfisher took another wrong path in the position below with the move 26...e5. Once again I threw my advantage away, this time with the move 27.Bc3. 27.Qf5 was probably the best move.

My 27th move was only good enough for a draw, but luckily for me, rayfisher played 27...Bf7 in reply, which allowed me to play 28.Qf5 and get the winning advantage. For the first time in the game I was able to take the advantage and keep it for awhile. I did not play all that accurate moves, but when we reached the position below, I played 36.b3 allowing my opponent to get back into the game again. I should have played 36.Bxf5 instead. Rayfisher's next move was a bit sloppy and I could have taken a clear advantage, had I answered 36...Raf8 with 37.Bxf5 or 37.h3.

My 37th move Rfe1 was only good enough to get a drawish position. The game continued to played evenly until my opponent blundered again in the position below with the move 47...h5?? The path towards was a narrow one, only by playing 47...g5 rayfisher could have kept the equality in the position. Rayfisher's 47th move could have been another losing move and while my reply at first was good enough for a winning advantage, I was not able to keep it until the end.

Actually, only my reply 48.d5 was a step into the right direction, but then my reply 49.Ra1 to 48...a3 threw away all my advantage. The next position of interest came after my 50th move in the position below. Rayfisher blundered in the position and played 50...Ra7?? I obviously did not see tactics in this game, but I should have seen the move 51.Rxa2! The point of it is that I would have won a pawn because if 51...Qxa2, I would have taken on f6 with check.

In the game I played 51.Rf2 and the game looked to be going towards a draw again. The draw was agreed upon after 54.Qxf2.
