C55 Two Knights: 4.d3, 4.d4 exd4 5.e5 and Max Lange Attack (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.O-O Nf6 5.Re1 O-O 6.Nc3)

C55 Two Knights: 4.d3, 4.d4 exd4 5.e5 and Max Lange Attack (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.O-O Nf6 5.Re1 O-O 6.Nc3)

Well, this does not happen often, during the 24 moves that this game lasted, no clear mistakes were made by either player. This was played in a team match between Limitless Chess and Команда ЦФО (Russia Central Federal District) on 80 boards. I played on board 28 for Limitless Chess and in addition to this draw, I won my other game against Andrey-25. This was very tightly fought match, the final score was 79.5 - 80.5 in favor of Команда ЦФО (Russia Central Federal District). Maybe the only real opportunity during the game for one of the players to get some kind of advantage was after my 22nd move h6.

Maybe the best way to get the initiative and force me on the defensive was to play 23.Ra6 and target my weakest pawn on d6.

The game quickly ended in a draw after that with the moves 23.Qe2 Rc8 24.Qc2 Qb7. The final position is not really a dead draw in the sense that the players can still try to fight for the advantage, but neither side wanted to take risks, so draw was a natural outcome.

C50 Hungarian Defence and Giuoco Pianissimo (1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4 Be7 5.c3 Nf6 6.e5 Ng4 7.cxd4)

C50 Hungarian Defence and Giuoco Pianissimo (1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4 Be7 5.c3 Nf6 6.e5 Ng4 7.cxd4)

This is one those lines that may not be that good all the way through, 6...Ng4 is a move that creates problems for Black. If it were possible that the knight could continue on taking on e5, then the move Ng4 would have been justified, but because Gluecifer7 could just reply with 7.cxd4 and prevent me from taking the pawn on e5 in favorable circumstances, my knight was very poorly placed at g4. I tried to be clever and played 7...d5, so that I would provoke the move 8.exd6 in reply. Had that worked, I could have taken back with my bishop and if need be, I would have been able to retreat with my knight to f6. Gluecifer7 did not want to allow me to the improve my options, so my opponent played 8.Bb5 instead.

6...Ne4 seems like the best way to go. From e4 the knight could go to g5 or c5 and maybe later to e6.

Then I moved my pawn to h5 in order to protect the square h6 with the rook, so that when my knight needs to move, I would have a decent square to retreat to and I could keep my pawn structure intact. Gluecifer7 then played 9.Qc2, which seems like a logical move that threatens to take on c6 twice and perhaps to win a pawn in case that Black does not properly respond to the threat. The threat was not at all severe, since I was able to reply with Bd7 and the position was only slightly in favor of Gluecifer7. The next time when I chose a path to ruin was when I played 14...Qb4.

The best move according to Stockfish 8 64 POPCNT is 14...h4 at depth 36.

The queen was moved to b4 in order to add pressure towards the pawn on d4, but it was a rather futile move, since it was replied with Bd2 and my queen had to retreat. Therefore I just basically gave my opponent a free move to catch up on development. The game continued with the moves 15...Qd6 16.Bf4 Qd7 and then Gluecifer7 played 17.Nbd2, after which the position should be roughly even again. It did not take long for me after that to make the game losing blunder, which was 18...Re7.

18...h4 would have been a much better choice than what I did, according to the engine at depth 34.

The move 18...Re7 may seem quite harmless at first, but it was a rather unnecessary move since I was not going to double my rooks on the e-file, nor was I going to need further defence of c7. Gluecifer7 played 19.Nc5 and the rest of the game was rather smooth sailing for my opponent apart from maybe the move 21.Nd3, which was unnecessary retreat of the knight. The knight was placed there in order to prevent the loss of the exchange, but there was a better way to do it, which started with the move 21.Rxe7+. The rook trade would have given the rook from f1 time to move and not be in the bishop's scope anymore.

B01 Scandinavian Defence (1.e4 d5 2.exd5 Nf6 3.d4 Bg4 4.Be2 Bxe2 5.Qxe2 Qxd5 6.Nf3 e6 7.O-O Nc6 8.c3 O-O-O)

B01 Scandinavian Defence (1.e4 d5 2.exd5 Nf6 3.d4 Bg4 4.Be2 Bxe2 5.Qxe2 Qxd5 6.Nf3 e6 7.O-O Nc6 8.c3 O-O-O)

The first big mistake of this game was seen when I chose to play 14.Ne1. It was another passive move that could have cost me one of my games. Not sure what I thought would happen in case I move my knight to g5, maybe I thought it would be lost, but once again, I would have been wrong. There would not have been any way for my opponent to take advantage of the knight on g5, the knight would have threatened a fork on f7 and because Gluecifer7 would have needed to protect f7, I would have had time to protect my knight. Retreating with the knight to e1 hampered the coordination of my pieces, my rooks were not connected anymore.

The only good move is 14.Ng5, according to Stockfish 8 64 POPCNT at depth 34.

In order to take advantage of my blunder, Gluecifer7 should have replied with 14...Nxe5 and the continuation 15.dxe5 Qe4 does not look good for me as all of my pieces would be badly placed. Luckily for me, Gluecifer7 played 14...Rh6 for some reason that I do not fully understand, maybe it was only made so that the knight on f6 could move freely again. It did not take long for me to blunder again, with my 16th move Qe3, my position went down the drain again.

16.Bxf6 is the move that the engine recommends at depth 40.

It did not matter, however, because Gluecifer7 was not able to find a strong move in reply. Both 16...h3 and 16...Nxe5 would have meant huge problems for me, but Gluecifer7 played 16...Rdh8, which let me off the hook as it only defends the rook on h6 instead of going for the attack. I continued the game with 17.c4, which basically forced the queen to retreat, since 17...Qe4 is answered with 18.Qxe4 Nxe4 19.Bxh8. My opponent went all the way back to d8 with the queen, which was one square too far as it made the reply 18.Nb5 look a bit more annoying. Gluecifer7 thought it best to protect the c7 pawn with 18...Bd6 and had I taken on d6 with my bishop, I could remained on the clearly favorable side of the board, since I would have been the one with the initiative. The problem with Nxd6 was that after cxd6 I could not play Qf4 and thus increased pressure towards d6. In the game I had to move my bishop and I chose to move it to f4, which was better than taking on f6. My final mistake saw the light of day when I played 26.Qd2.

My best try was 26.Qe4, according to Stockfish 8 64 POPCNT at depth 34.

The queen moved out of the defence and in an awkward square that the reply 26...Nd4 would have taken advantage of. In some situations the knight would have threatened to go to f3 and fork the queen and king, though it probably does not quite work immediately. In the game Gluecifer7 chose to play 26...h3, to which I replied by moving my g-pawn one square forward. It left the square f3 unprotected so naturally my opponent continued with 27...Nd4. The game did not last long after that as I resigned after 29...Qe4.

D35 Queen's Gambit Declined: Exchange Variation (1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.cxd5 exd5 5.Bg5 Be7 6.e3 O-O 7.Bd3 b6)

D35 Queen's Gambit Declined: Exchange Variation (1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.cxd5 exd5 5.Bg5 Be7 6.e3 O-O 7.Bd3 b6)

This line is playable up to the move 7.Bd3. Even though I did not get punished from my 7th move, b6, I should remember in the future why the move is so bad. The reason why my move was so bad can be seen in the variation 8.Bxf6 (removing the defender of both d5 and h7) Bxf6 9.Qh5 (threatens both mate on h7 and the pawn on d5). It is interesting that this rather simple idea was missed by my opponent even though he or she is quite strong. I guess it is possible that my opponent did not want to win so easily and gave me a chance to fight on. Skw123 played 8.Rc1 in the game and the position was roughly even again.

I should have played, for instance, 7...c6, 7...Nbd7 or 7...Re8, according to Stockfish 8 64 POPCNT at depth 36.

The next turn for the worse from my point of view happened when I played 11...c5. Skw123 could have then played 12.Qf5 in order to target the pawn on d5, but I could have just replied with 12...g6 and kick the queen maybe to h3. While the engine thinks that after 11...c5 the position is clearly favorable to White, it is not so clear to me why that is. One reason for that may be that is the fact that the material is even and there is no clear attack for White in my opinion. White does have better placed pieces and it may be enough for the advantage, but converting that advantage to a win seems quite difficult.

The best three moves according to the engine are 11...h6, 11...Re8 and 11...c6 at depth 37.

The game continued with the moves 12.Rfd1 c4 and then skw123 played the passive 13.Qb1, after which the position does not seem so good for my opponent again. A much better try was to play 13.Qf5, because at least in that case skw123 would have had the initiative. I then moved my pawn to a6, in order to control the square b5 and maybe prepare the eventual move b5, followed by b4. It was perhaps not the best move, but even with that move the game continued in only slightly favorable way to skw123. During the rest of the game I managed to avoid serious mistakes and we agreed to a draw after 42.Nxh7. Probably the best chance for my opponent to win the game then was after my 7th move because after the continuation mentioned above, I would have likely resigned soon after 9.Qh5.

This game was played on the first round of the 1800+ 7 Days tournament at Chess.com. I was 6th in the final standings of group 5, I managed to get only 5.5 points in 14 games. It meant that I was eliminated from the tournament and could not advance to round two. My opponent in this game, skw123, was able to get 11 points in 14 games and was 2nd in the final standings of the group.

Well, it does make me feel a bit better about my 7th move when I searched my reference database and found players who are much stronger than me and also made the mistake 7...b6.

B33 Sicilian: Pelikan and Sveshnikov Variations (1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 6.Ndb5 d6 7.a4 a6 8.Na3)

B33 Sicilian: Pelikan and Sveshnikov Variations (1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 6.Ndb5 d6 7.a4 a6 8.Na3)

The game I am sharing today was played in a team match called TMCL 2016 Sub-Div. WL1 R3. It was played between Battle For Victory and TribaL KnighTs on 100 boards at Chess.com. I played on board 52 for Battle For Victory and won both my games against Zalan10 on time. The first sign of trouble for Zalan10 was when he or she played 11...Rc8. I replied with the move 12.Bg5, which pinned the knight to the queen and discouraged my opponent from playing d5, because it would lose a pawn. Zalan10 then played the natural looking developing move 12...Be7, which gave the opportunity to my opponent to move the knight, in case he or she would have wanted to do so.

Zalan10 should have played 11...d5 and improve the scope of the dark-squared bishop and get rid of the possibly weak pawn at d6.

I should have then played 13.Bxf6, in order to prevent the move d5 and also to make sure that knight could jump to d5 without the possibility for it to be immediately challenged. I instead castled, which was a decent move, but not the most accurate one. Nor was the continuation that followed it. Zalan10 played 13...h6, which gave me another chance to take the knight on f6 with my bishop and jump with my knight to d5, but because I still preferred my bishop to Zalan10's knight, I simply retreated with the bishop to e3. Even though I should know by now that I should more often than not, to go with the aggressive move instead of the passive alternative, I almost always go with the passive one. The blunder that decided the outcome of the game was seen on move 16, when Zalan10 played Qd7.

The move that Stockfish 8 64 POPCNT suggests in this position at depth 34 is 16...Nxd5. In that way Zalan10 could have still fought for the draw.

The rather obvious problem with Zalan10's move 16...Qd7 was that I could reply with the move 17.Nb6, which forked the queen and the rook. After I had won the exchange, the game was quite easy to play and I never gave my opponent a chance to get back into the game.

C55 Two Knights: 4.d3, 4.d4 exd4 5.e5 and Max Lange Attack (1.e4 e5 2.Nf3 Nc6 3.Bc4 Be7 4.O-O Nf6 5.d3 O-O 6.Bg5 d6 7.h3 Be6 8.Bb3)

C55 Two Knights: 4.d3, 4.d4 exd4 5.e5 and Max Lange Attack (1.e4 e5 2.Nf3 Nc6 3.Bc4 Be7 4.O-O Nf6 5.d3 O-O 6.Bg5 d6 7.h3 Be6 8.Bb3)

This is just one of the many team match games I have played at Chess.com. The match was played between La Belle France and FIGHTING GLADIATORS on 19 boards. I played on board 2 for La Belle France and I managed to win both of my games against sadnadeem. The game below I actually won on time, but the other one I won when my opponent resigned. More importantly, our team won the match with a score of 25 - 13. Unlike usual, this game only has one clear moment where the the game goes down the drain for one of the players. For the first 18 moves, both players made reasonable moves, but then sadnadeem played 19.Ne3 and the downhill started for my opponent, from which he or she did not recover from.

19.N5h4 seems like the best way to protect the knight on f5. At depth 35 Stockfish 8 64 POPCNT the position should be roughly even after that.

Had sadnadeem played 19.N5h4, it would have basically prevented the move f5 in reply due to the continuation 20.Nxg6 fxe4 21.Nxf8 Rxf8 22.Rxe4 and I would have been down a pawn. In the game I continued with the move 19...f5 and took the initiative. Due to the fact that the knight blocked some squares from the rook, it only had two safe squares to go to, c4 and a4. Sadnadeem chose to move the rook to c4, which was the riskier square to land on, because the rook had a higher chance to run out of squares there than it would be at a4. I tried to trap the rook as best as I could and continued the game with 20...Qd6, in order to take the square c5 away from the rook and continue with b5, forcing the rook to go to c3, which would be the only safe square for it at that moment. In order to give the rook more options, sadnedeem should have replied by moving the rook to a4 on move 21, but instead my opponent played 21.Qe2 and the position was lost for White.

Hmm, it is interesting to me that the game below did not appear as one of the reference games when I analysed my game. In the notation there is a N after 8.Bb3 to mark it as a novelty, which does not seem to be the case at all. This should have been in my database back when I did a full analysis to my game, so I am not sure how the reference games are determined that analysis. I actually found other games that had reached the position after 8.Bb3 in that same database, but I am not adding them here since the ratings of the players are not shown or they were quite low.

D02 1.d4 d5 2.Nf3 sidelines, including 2...Nf6 3.g3 and 2...Nf6 3.Bf4 (1.d4 Nf6 2.Bf4 d5 3.Nf3 g6 4.e3 Bg7 5.Bd3 O-O 6.c3)

This was played in a team match called Open Challenge Kartik City. It was played between Kartik City and Philippine Critical Movers on 32 boards. I played on board 10 for Kartik City and lost both my games. We also lost the match with a score of 22 - 42, so it was not even a close match. The first really odd and bad decisions from me was to play Kh8 on move 10. It is rather sad that I could not come up with a better move than Kh8, which seems to be just a waste of a move. I have to admit though that even now it would be somewhat hard for me to come up with a useful move in that position, but I would probably play something else than Kh8 if I were to reach that same position again.

The Stockfish 8 64 POPCNT's recommendation on move 10 is a5 at depth 35.

Because I basically gave a free move to my opponent, DChris should have been doing quite well at this point in the game and indeed my opponent's position should be favored after 11.Rg1 even if it was not the strongest move. Moves like 11.Ne5 and 11.O-O-O make a lot of sense, castling long helps the a-rook to join the attack on the kingside and the knight on e5 targets the undefended pawn on f7. Had the knight jumped to e5, I would have probably moved my king back to g8, because Nxe5 seems quite bad in view of dxe5 and my knight from f6 would need to retreat to g8. A few moves later I played 13...b5, which could have been the move that lost me the game, had my opponent not made some bad moves later on in the game.

My best chance according to the engine was 13...Nxe5 at depth 31.

I thought that I need to make some counterplay on the queenside, since my opponent would be likely to castle there and therefore I chose the move b5. However, it did not even threaten b4 immediately due to the continuation Nxc6 Bxc6 cxb4. I was quite lost or in serious trouble up to my 19th move fxg6, but then DChris played 20.dxc5, which gave me my last chance to get back into the game. I simply took back on c5 with my queen, which was a good enough reply to fight on for a possible draw if the engine is to be believed.

DChris should have just played 20.Rh1 and use semi-open h-file to his or hers for attacking purposes.

My final mistake was seen when I played 23...Nxe5, which was also my last move of the game.

23...Rf6 was much better than what I did.

I resigned after the reply 24.Bxe5, but 24.Qxe6+ was an even better move and would have also ended the game. Due to the Qxe6+ possibility, I had to play 23...Rf6 in order to defend my position. It would have both attacked the queen and defended my bishop and avoided the mate, which was threatened at h7.

C45 Scotch Game (1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Nxd4 Bc5 5.Nxc6 Qf6 6.Qf3 Qxc6)

C45 Scotch Game (1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Nxd4 Bc5 5.Nxc6 Qf6 6.Qf3 Qxc6)

This was played in a team match called REMATCH and it was played between France-Deutschland Group and LullabyVisca on 103 boards. I played on board 34 for LullabyVisca and managed to win both of my games against boubalex. The match ended with a score of 63 - 143 in favor of LullabyVisca. The first position in the game that I want to take a closer look at is the one after my 19th move Qg6. Boubalex played 20.Qh4, possibly trying to avoid a queen trade, but it allowed me to play 20...Be4, which threatened both the pawn on d5 and mate on g2. There really was no way that my opponent could have defended against both threats, but boubalex's next move made things even worse for him or her. Boubalex blocked the queen's path to g2 with the dark-squared bishop by moving it to g5.

The four best moves that Stockfish 8 64 suggests at depth 47 in this position are 20.a4, 20.Kf1, 20.Kh2 and 20.Bc4.

Moving the bishop to g3 was a much better way of blockading the path of the queen, because I would not have had a way to immediately threaten the bishop on the g-file with a pawn. Had I indeed played 21...f6, the rest of the game would have been much easier for me, but I probably thought that boubalex could just counterattack my bishop on e4 and I did not like the way it looked to me. In the game I just chose to win a pawn and played 21...Bxd5. It was answered with 22.Rad1, a move that would have allowed me to play 22...f6 once again with a winning advantage. The reason for that was that the bishop on g5 still could not move due to the mate on g2 and if 23.Rxd5 would be played then I would take on g5 with my f-pawn, threatening the queen on h4 with the pawn and at the same time Bxf2+. The combined threats would have meant an easy win for me. Alas, I played 22...Bb3 and missed the easy win. Even then, I should have been on the better side of the board after that. The next diagram shows the position after 27...Qf7. In the game boubalex played 28.f4, which was the final nail in the coffin.

The only way that boubalex could have possibly tried to survive, started with the move 28.Re2, according to the engine.

After 28.f4 the game was completely lost for my opponent, to which I was able to find the strongest move 28...Bc4, but I was not able to continue the game in the most accurate way possible. For instance, to 29.Qg3 I replied with 29...Bxd3+, when 29...Re3 was obviously a better move. Boubalex finally resigned in a position where I would have won a second pawn and likely a third one as well.

Game number two. This game was played in the first round of the 2014 October Glacial Super Casual Banded I 1650+ tournament at Red Hot Pawn. As it so happens, the two other games I added today were played in the same tournament as the game below and the things I typed about this tournament are still unchanged, so I will not type all that much about it here. I played this game quite decently apart from two moves, 29.Qe1?? and 31.Qa5??, both of these moves could have ended up in my loss but the first one I survived because my opponent did not take advantage of my mistake. The second one was the final mistake of the game and I could not bounce back from it. My opponent did play well in this game and he has also played very well in this tournament because he has not lost a single game and leads the tournament and has the best chances to win the group aswell because his maximum possible score is higher than any other player's maximum possible score.

Even though my games have gone quite badly at Red Hot Pawn lately, my latest game from there did bring back some of my confidence back because I won a game against a player who was rated 2061. That win brought me back over 1800 once again. The fact that I managed to decrease my rating from 1900+ to less than 1800 in fifteen games, I started to be quite worried about my playing skills. I started to think that maybe I have not improved in chess at all that much in years. During the same time period I played two over the board blitz tournaments at the club and won both of them without losing a game. I have never been able to win two of those blitz tournaments in a row before, so that would either suggest that I have indeed improved my chess skills or the people who usually have played there have become worse over time. I would like to think that the first scenario is more likely.

Game number three. The game below was played in the first round of the 2014 October Long Haul Split I tournament. The tournament takes place at Red Hot Pawn, the place where I played my first correspondence games in 2004. With this win I overtook beatlemania (1740) in the standings and now I am leading the tournament by a difference of one point.

E20 Nimzo-Indian: 4.g3 and 4.f3 (1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Bd2 b6)

E20 Nimzo-Indian: 4.g3 and 4.f3 (1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Bd2 b6)

This game was played in a team match called TMCL 2016 Div C R4 OCD v World Friendship. It was played on 57 boards and I played on board 22 for Obsessive Chess Disorder. I helped the team to win the match by winning both of my games against Susi. The final score of the match was 79.5 - 34.5 in favor of Obsessive Chess Disorder. The first time that a clear mistake was seen during this game was when Susi played 18.Qc2. It was bad because of the continuation 18...dxc4 19.bxc4 Bxf3 20.gxf3 cxd4 21.exd4 (this same line is seen in the game notation). In that line after 21.exd4, White is left with doubled isolated pawns on the f-file, isolated pawns on the a-file and on the h-file and total of five pawn islands against Black's two. Due to the pawn weaknesses Black should be clearly better.

18.dxc5 would have been the way to go.

Alas, I did not go for the move 18...dxc4, but instead simply protected my h-pawn by pushing it to h6. After this passive move the position should be about even. The second clear mistake was seen when Susi played 21.Bb4. With that move Susi allowed me to win a pawn, had I moved my queen to c6, so that Susi could not have taken on d4 with the knight due to the mate on g2. For some reason I moved the queen to c7, which was much less effective square for the queen. I should have been somewhat better even after 21...Qc7, but it allowed Susi to take on d4 with the knight and get the pawn back safely.

Susi needed to take back on d4 with the knight, in order to stop Qc6 and maintain material equality.

Luckily for me, Susi played 22.exd4 instead and his position started to completely fell apart. I then took the knight on f3 with my bishop, because it removed the defender of the pawn on d4, so that when Susi replied with 23.Bxf3, I could finally be up a pawn because I was able to take the undefended d-pawn with my remaining bishop. The rest of the game was quite easy for me to play and while I did some inaccurate moves, I always remained at least in a clearly favorable position and eventually after my 39th move Qd3+, my opponent resigned.

C60 Spanish Game: Unusual Black 3rd moves and 3...g6 (1.e4 e5 2.Nf3 Nc6 3.Bb5 Nge7 4.O-O g6 5.d4)

C60 Spanish Game: Unusual Black 3rd moves and 3...g6 (1.e4 e5 2.Nf3 Nc6 3.Bb5 Nge7 4.O-O g6 5.d4)

For the unforeseeable future I am posting games that I have not posted before. When I have gone through my older posts and changed the names of the posts according to the way I am naming them now, I will get back to posting my previously shared games in case that the games in the older posts would no longer be categorized the same way as the other games in that post. So, now for the game I am sharing today. It was played on the first round of the EXPECT NO MERCY - NAZARETH TOUR!!! I managed to get 6.5 points in 8 games, due to which I won the group with a half a point difference. This game was especially important because my opponent in this game, csabiu, was second in the final standings of group 7. Only the winner advanced to the second round, so I was the only one to advance to the second round that is currently in progress. On round two I am on second place in the standings and I have finished 3 out of the 8 games that I need to play on this round.

This game featured only one critical moment and it was seen after my 7th move Be2. Csabiu moved the knight to a5, which was maybe the worst square for the piece. The reason for it was that the knight had no safe squares to which it could go. I took advantage of that fact and threatened the knight with my b-pawn.

The best square for the knight was d4.

Csabiu's best move might have been to move the knight back to c6, because in that case my opponent would have at least been able to get something in exchange for the knight. In the game csabiu played 8...d6 and did not even try to get a pawn for the knight. This meant that the rest of the game was really easy for me to play. Only a bit later did my opponent get a free pawn, but it did not really improve csabiu's chances and after my 22nd move Rab1 csabiu resigned.
