C01 French: Exchange Variation (1.e4 e6 2.d4 d5 3.exd5 exd5 4.Nf3 Bg4 5.Be2 Nf6 6.O-O)

C01 French: Exchange Variation (1.e4 e6 2.d4 d5 3.exd5 exd5 4.Nf3 Bg4 5.Be2 Nf6 6.O-O)

Well this game should not have been a draw if you look at the position where this game ended. White should be winning but I guess this game had gone too long because my opponent offered a draw and I of course accepted since my position is really bad. I tend not to resign that easily as I don't like it all that much. Usually only after my opponent has a forced win, I resign. And I never offer a draw in a position where I think I am lost. I only offer a draw when I think the position is a dead draw or in some friendly games when my opponent needs to leave before finishing the game. The game below was played in the first round of the tournament called Maximum ! and it was only fifth game to finish for me. As I look at the cross table, I am clearly the slowest person to finish my games. There are twelve players in the group and the best tree will advance to the next round. I have added two mate in ones, two mate in twos and one mate in five puzzle. I have also added a game to these two posts: E00 Indian Game: East Indian Defense and E11 Bogo-Indian Defense: Exchange Variation.

This paragraph and the ones that follow it in this first game have been added November 24th, 2016. I think both players played reasonable moves until we reached the position after 21.Rxe6. You can see that position below. I am not sure what I was thinking at the time, but I played 21...fxe6. I assume that I wanted to get away from the symmetrical pawn structure in order to get some imbalance in the position and maybe avoid the draw. I kind of succeeded, but not in the way I would have liked. The move 21...fxe6 is just bad in many ways. It weakens the g6 square and it creates a backward pawn on e6. I usually try to play in a way where my pawn structure remains healthy, so my 21st move is a bit uncharacteristic of me.

21...Qxe6 was the better capture.

The game continued to go rapidly downhill for me as you can see in the game continuation 22.Re1 a6 23.Qg6 Rd8. The point of playing 22...a6 was to prevent Qb5 after Re8. However, the move 23.Qg6 showed how pointless my 22nd move actually was. The best way to handle the position was to play 22...Qd7, it stops Qb5 and in case of Qg6, I could play Re8 and maybe hang on in the game. My position was really horrible after 23.Qg6, but I made things even worse with the move 23...Rd8 because it should lead to further material loss. While writer15 did not find the best move, my opponent still had a winning advantage after 24.Rxe6.

A42 Modern Defence: Averbakh Variation (1.e4 g6 2.d4 Bg7 3.c4 d6 4.Nc3 Nf6 5.Nf3 O-O 6.g3 e5 7.Bg2 exd4 8.Nxd4 Nc6 9.Nxc6 bxc6 10.O-O Nd7 11.Qc2)

A42 Modern Defence: Averbakh Variation (1.e4 g6 2.d4 Bg7 3.c4 d6 4.Nc3 Nf6 5.Nf3 O-O 6.g3 e5 7.Bg2 exd4 8.Nxd4 Nc6 9.Nxc6 bxc6 10.O-O Nd7 11.Qc2)

This is the first game of mine where the ratings of both players are over 2200. This also might be the only one for quite some time unless I am able to somehow get back over 2200, since this game dropped my rating four points. It is good to get these tough opponents on regular basis, to test my skills against them. I have now played five correspondence games against players who are rated over 2400 and my score in them is zero wins, one draw and four losses. I may not be strong enough to give these players much in the way of resistance but that draw might be sign of it being possible, how ever rarely it might occur. The game below was played in the second round of the AUTO-MASTER-2088 tournament. It is a tournament that was open to only rated players between 1900 and 2300. It is rare that tripled pawns are any good but maybe this game showed that having tripled paws might not be always that bad. This loss of mine made certain that my opponent in this game, Luke2015, wins the tournament no matter what happens in the last remaining game of the tournament between the same two players who fought in this game. I did secure my place as the second in the tournament already when I drew and won against the third participant in this second round some time ago. I have added three mate in ones, one mate in three and one mate in four puzzle today.

Chess960 SP71

Chess960 SP71

One might say it is about time there was another #Chess960 game featured here. The thing is that I have mainly tried to feature chess games so that I can finally know how many opening variations I have played in my time. I do not think that I have featured all the openings I have played yet but for the moment I could not find a new one that I had not covered here. The other thing is that I have not played that many Chess960 games yet. I still have not lost a single game of it, though avoiding it has become extremely hard. So far the score from fifteen games is 13 wins and two draws. I have some games in progress but I hope to increase the amount of Chess960 games in the future by a large amount. I know that the way I look at those different starting positions differs a lot from the way good players play them but so far I have done quite well without ever really looking at Chess960 games from different databases and determining what I should play. I like to keep my thinking as fresh as possible and kind of discover myself what works in what starting position. I have added games to the following posts today: B13 Caro-Kann Defense: Exchange Variation, C96 Spanish Game: Closed Variations. Closed Defense, E24 Nimzo-Indian Defense: Saemisch Variation. Accelerated, C64 Ruy Lopez: Classical Defense and C10 French Defense: Normal Variation..

Game number two. This time I guess the winds of change are blowing and I can actually post here analysed versions of my Chess960 games. This game like the one above this was played in a team match called Respect Freedom :). It is a 42 board match played between ♦♦ Respect ♦♦ and Historical Association. I played board 23 in this match for Historical Association and I managed to win both my games. The knowledge of that does not warm me that much as our opponent has secured the win because they lead the match 45,5 - 33,5 at the moment I type this. This game was added March 18th 2015.

A22 English Opening: 1...e5 2.Nc3 Nf6 (1.c4 Nf6 2.Nc3 e5 3.g3 Bb4 4.Nd5)

A22 English Opening: 1...e5 2.Nc3 Nf6 (1.c4 Nf6 2.Nc3 e5 3.g3 Bb4 4.Nd5)

In this game I tried to play the English again in order to see if I could play it again but the way that this one went I maybe stick to other opening moves for now. Well, this was just one game but still I feel more comfortable by playing 1.e4, for example, even though it may also end up in positions that I do not really like. The game you see below was played in a team match called the WOLF. It is an ongoing match between The WOLF and ♙ Thematic Matches & Tournaments. It is played on 48 boards and I am playing board 3 for The WOLF in this match. When I looked at all the players that play or finished their games on this match, I noticed something positive about it, no one had their accounts closed during this match! Still too many timeouts though. The score in the match is 19,5 - 64,5, so the winner is clear even now and it is ♙ Thematic Matches & Tournaments. I have added three mate in twos, one mate in four and one mate in eight today.

Game number two. This really short game was played in a team match called Great Viking Warriors vs. Kopaonik. The match is played on 90 boards and I am playing on board 18 for Kopaonik. The current score in the match is 43.5 - 65.5 in favor of Kopaonik. Even if the current score looks really good for us, the match is still far from over.

B13 Caro-Kann: Exchange Variation and Panov-Botvinnik Attack (1.e4 c6 2.d4 d5 3.exd5 cxd5 4.Nf3 Nc6 5.Be2 Bg4 6.O-O e6 7.Nc3)

B13 Caro-Kann: Exchange Variation and Panov-Botvinnik Attack (1.e4 c6 2.d4 d5 3.exd5 cxd5 4.Nf3 Nc6 5.Be2 Bg4 6.O-O e6 7.Nc3)

This one of the four games that my opponent lost on time during the same day against me. The game was played in a team match called Art of Chess vs VIP ChessQueen. It is an ongoing match between Art of Chess and VIP CHESS. In this match I played board 5 for VIP CHESS. It is played on 46 boards and the current score is 57 - 31 in favor of Art of Chess which means they have already secured the win even before all games are finished. According to the analysis shown below I did not have all that much to say in this match as my opponent was the one who could have gained an advantage but did not manage to do it.

As I checked today how many games I still have in progress, I was somewhat surprised to see that my game load had decreased to 262 games from the 300 games I had in progress January 12th 2015. Well, the 300 games did not last but a few hours actually but it was nice to get it when I did. The amount of finished games is actually more than 38 games as there have been more games added to the load during this time. If the last part of 2014 I was able to increase my ratings steadily, this year has started to decline my ratings somewhat. The only site where I have been able to keep up increasing my rating has been Queen Alice Internet Chess Club but then again it might start ever so slight decrease soon. It is easier to keep the rating close to where it is there as I only have 3 games in progress there currently. There is of course also one site where I seem to stay in the same rating or close it all the time and that is GameKnot for some reason. I have added two mate in ones, one mate in four, six and nine puzzle today. Until tomorrow, my fellow chess enthusiasts.

The game I share with you today is from a quite big team match called AoC vs R&J TM. It is played on 100 boards between Art of Chess and Romeo and Juliet. I played board 12 in this match for Romeo and Juliet and I managed to win both my games on time. Had the time not be a deciding factor in these games, the result might have been quite different. The current score in the match is 97,5 - 76,5 in favor of the home team that is in this case Art of Chess. The thing that occurs way too often in these matches is timeouts and accounts closing and this team match was no exception. Both teams had two people who had their accounts closed during the match. Art of Chess has lost more games on time out than Romeo and Juliet so far but I do hope that there are no more losses on time in this match. I have added one mate in one, two and three and two mate in six puzzles today.

B79 Sicilian Dragon: Yugoslav Attack, 9.Bc4 Bd7 10.O-O-O Qa5 (1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 d6 6.Be2 g6 7.Be3 Bg7 8.f3 O-O 9.Qd2 Nxd4 10.Bxd4 Qa5 11.O-O-O Be6 12.Kb1 Rfc8)

This might very well be the only game in this blog not to have a reference game included in the notation. This is because when I used my normal settings to analyse this game, the program did not commentate the first 18 moves of the game in any way. As there was already the move that lost me the game included I found it strange. There was only one reference game apparently for this game and apparently as the program uses this reference database for checking the opening, it may have mistakenly thought that it was something that can be played. I know that the way I have analysed games is not perfect but never thought that this kind of problem could exist. After trying to analyse this game twice with my normal settings, the second try was mainly intended to check if I had mistakenly put the last move to be checked by the program something other than move number one. As I got the same result as with my first try, I left the opening reference out of the analysis, so that it would not see if the moves were previously played from the reference database. After I did that I got in my opinion better analysis.

The game below was played in a tournament called 2014 September Octet I 1700-1800. This is a small eight player tournament where it is all versus all with both colors. The winner has already been decided and that was my opponent in this game, AttilaTheHorn. He won all but one game in the tournament and even that was a draw, so he was undefeated! I can get a second place finish in case I win both of my games that are still in progress. Well, I can get the second place also if I get a win and a draw from the last two games. Maybe the most important moment of the game was seen after the move 14...b5.

The best move according to Stockfish 8 64 POPCNT at depth 34 is 15.Nd5.

I did move my knight, but unfortunately to a very passive square a2. I probably thought about the move 15.Nd5 in a superficial way and thought it to be unplayable. After my 15th move it was all downhill for me, and I resigned after 19...b3.

C91 Closed Spanish Game: 7...d6 8.c3 0-0 9.d4 (1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 b5 5.Bb3 d6 6.c3 Be7 7.O-O Nf6 8.Re1 O-O 9.d4 Bg4 10.d5 Na5 11.Bc2 c5 12.dxc6 Nxc6)

C91 Closed Spanish Game: 7...d6 8.c3 0-0 9.d4 (1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 b5 5.Bb3 d6 6.c3 Be7 7.O-O Nf6 8.Re1 O-O 9.d4 Bg4 10.d5 Na5 11.Bc2 c5 12.dxc6 Nxc6)

This is an example of those games where I could have lost many times during the game but did not as my opponent was not able to make use of his possibilities. So, in that regard I am lucky to even have drawn this game as I never really had an advantage during the game. It is interesting to see in the notation that the reference games are quite old even though I keep my reference database updated each week. I guess not that many players have played like this in many years or have not ended up in the database. This game was played in a tournament called 2014 August Grand Seven Fourteen III. This a tournament where I can only hope for a third place finish as the two first places are too far ahead of me in points that I can't reach them anymore. I have added two mate in ones, two mate in twos and one mate in eight puzzle today. Until tomorrow, my fellow chess enthusiasts! As always, if you have any feedback to give, please leave a comment, it would be much appreciated.

C20 1.e4 e5: Unusual White second moves (1.e4 e5 2.c3 Nf6)

C20 1.e4 e5: Unusual White second moves (1.e4 e5 2.c3 Nf6)

Today I post two games in this same new opening straight away as I saw that the the two consecutive games in my database were played by the same players and as it so happens, also the same opening. The game below was played in a tournament called 2014 August Grand Seven Fourteen II. It is an ongoing tournament held at Red Hot Pawn. As majority of the games have finished only two players still have chances to win the tournament and I am one of them. I have secured at least fourth place in this 21 player tournament. Thinking times are seven days for each move and there are fourteen days in the bank to use in case you can't make a move in the seven days. In case you spend over seven days to think your move, your timebank starts depleting. Still you have seven days minimum to make your next move even if you used time from the bank. I have added two mate in threes, one mate in two, one mate in five and one mate in seven puzzle today. When I added my first puzzle today to mate in three section, I noticed that my opponent in that game had a rating of 2938! He or she is most likely the highest rated adversary that I have ever faced.

The second game was played in a tournament called 2014 August Grand Seven Fourteen III and it obviously is also held at Red Hot Pawn. The thinking times and the amount of players is the same as in the game above. The tournament also started the same day August 11th 2014. In both these tournaments you get 40 simultaneous games immediately when the tournament starts as you play with each color against everyone in the tournament. This tournament differs a bit from the other one in at least one aspect, I am no longer fighting for the win of the tournament but instead I fight for third place.

Game number three. This was played in a team match called Feb. 2015 Challenge(WL): 1701-1900 and it is played between CYBERMEN ELITE and TROY. I am playing on board 1 in this match for TROY. This is only played on three boards, so it is one of the smallest team matches I have been a part of. The current score is 1 - 3 in favor of TROY, so we have at least drawn this match already. In the two remaining games we only need a draw to win the match. This was a rather uneventful game and draw was agreed upon on move 17. The draw was offered by my opponent and I thought I should accept due to the fact that I had no real ideas on how to improve my position. Also the situation in the match was going good enough for us that draw was sensible to make at that point. If we would have needed every game to be won in order to win the match or even draw it, I would not have accepted the draw offer.

C89 Closed Spanish Game: Marshall Attack (1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.O-O Be7 6.Re1 b5 7.Bb3 O-O 8.c3 d5 9.exd5 Nxd5 10.Nxe5 Nxe5 11.Rxe5)

C89 Closed Spanish Game: Marshall Attack (1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.O-O Be7 6.Re1 b5 7.Bb3 O-O 8.c3 d5 9.exd5 Nxd5 10.Nxe5 Nxe5 11.Rxe5)

This opening reminds me of the game when Frank James Marshall played this against José Raúl Capablanca for the first time. Marshall had prepared the opening for years but when he finally got to play it against Capablanca, he lost. That is one of the old games that I remember going through some years ago. I have actually gone through other games from these players as well but that I remember the best. Well, not the game itself but the story related to it I remember to some extent.

The game below is my second game against ACW and both were played in the Team Match Champions League Division D, round one match between DEORLS! and THE VAMPIRE. I played both of my games quite badly, I am ashamed to admit and lost quite quickly. I played board seven for DEORLS! and these two games happened to be my first two matches representing them. Luckily other members of the team have had better success in their games and the score is tied 25,5 at the moment I type this. So even though I was not able to be all that much help as a player, maybe the fact that I joined and dropped some players to lower boards helped a bit at least. When I typed about the fact that I feel more confident about my moves yesterday, I had not yet gone through some of the moves I still had to do in my correspondence games. While I went through them, I noticed yet another blunder I had done, this time taking a pawn with my knight that I thought would be safe to do. It turned out I had miscalculated again or maybe thought that my opponent would play the moves in different order. He just took my knight and then I noticed that I can't take back as more terrible thing would be coming my way. I have to stop making these bad moves now or I will see myself dropping my rating hundred or more points due to silly blunders I should not do anymore. I should know better by now. I have added two mate in twos, one mate in three, one mate in four and one mate in six puzzle today.

Game number two. The game below was played on the first round of the Ruy Lopez tournament that is being played at Chess.com. This tournament started on October 10th 2014, so the first round has lasted clearly over a year now and it will last quite a long time still. One of my first round games has not even started yet... That is because you only play one game per opponent at a time, which seems silly in view of the thinking times used in the tournament. You can use 14 days to think about your every move. Well, not all of it, because then you would timeout, but close to it. I am playing on group #1 and from the 20 games that have finished so far, I have won all of them!! Not sure if the reason for this is more due to time consumption than anything else. Not all people seem to understand that this can take a long time to finish even if they are aware of the thinking times when joining the tournament. So when the duration of the tournament gets too big for them, they quit playing in the tournament.

The best three players of each group will advance to the next round and it is already clear who are those three players in the group I am in. It will be me, adamredsox24 and djsniper800. The only games in progress in group #1 are my games against adamredsox24, well actually the second one has not even started yet because of the silliness I explained earlier. There are still 16 games left to finish in this round, so it is unclear how long it will be until the next round can start. My opponent in the game below, bzalasky, finished fourth in this group with a score of 15 points out of the possible 22 points.

B41 Sicilian: Kan Variation: 5.c4 (1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 a6 5.Be2 b5)

B41 Sicilian: Kan Variation: 5.c4 (1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 a6 5.Be2 b5)

This game went first slightly worse for me on move 12 and move after that I blundered so badly that the game would have been resignable at that point. I tried to continue a bit longer but on move 20 I resigned as my position was completely hopeless. This game was played in the first round of the LA BELLE FRANCE TOURNAMENT 3. The tournament has 16 players on round one and they are divided in to groups of four. Two best players from each group will advance to the next round. I have only finished one game on round one so far, the loss you see below. Rating range in the tournament is 1751-2050 and the time control is 3 days per move. Around the time I played that horrible move, I also blundered in some other games as well and lost a couple of games under 20 moves. I played last weekend in a over the board tournament and the results there were somewhat promising that I may be able to get back to level of play that I once had. Well, talking about my rating to be exact, I think when I am able to concentrate on the games properly, I play better chess than I have ever played. My over the board rating has had some roller-coaster movement the past few years, I get it to my highest ever rating and then I plummet down a couple hundred points. This has happened a few times, usually ending with me taking a long break from chess. Since I started doing this blog, I think I have been able to improve my play quite a bit. I was able to get two wins against International Masters and one draw against a FIDE Master in 2014 and those results did gave me a confidence boost. Maybe I am doing something right when playing chess. The only problem I have is that my level of play is not all that consistent, some positions I play much better than others. I have added two mate in one, one mate in four, one mate in six and one mate in nine puzzle today.

The game below is the most recently finished game of mine from GameKnot. This was played in a tournament called tedjj's mini-tournament XLIII, it is a tournament where I have played worse than in any other correspondence chess tournament. I have only one win out of five games in that tournament so far and I am currently residing in last place. The time control in the tournament is 3 days initially but you get two days added to your time after every move you make though it is limited so you can think maximum of five days each move. There are 11 players in total joining this mini-tournament and you play each player twice so both have one White and one Black against other players. I have fifteen games left to play and try to alter the course of the tournament, it will be interesting to see if I keep losing games or can I start winning some games. My rating at GameKnot is one of the lowest I have in correspondence chess sites but I do have a decent winning percentage there, though lately that has come down a bit, currently at 71% chance of me winning. It is also the only correspondence chess site where I have not played any draws in the 52 games that have ended there. I have added three mate in ones, one mate in two and one mate in seven today for you to hopefully enjoy.

C92 Closed Spanish Game: 9...Be6, Karpov and Flohr-Zaitsev Variations (1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 b5 5.Bb3 d6 6.c3 Be7 7.O-O Nf6 8.Re1 O-O 9.h3 Bb7 10.d4 Na5 11.Bc2)

The moves in this one might be slightly out of order but the position after Black's 9...Bb7 is from the opening that is said in the title of this post. The game below is from the first round of the tournament called 2014 August Banded Threesomes I 1700-1800 and it is held at Red Hot Pawn. People are divided in to three player groups if possible as you may figure out from the name of the tournament. Round one is still in progress in one of the groups but the group I was in has already been decided and there were two players sharing the group victory, so both advance to the next round. Both of those players are featured in the game below. Thinking times are 3 days per move and 7 days are in the bank. I have added two mate in two, one mate in four and two mate in eight puzzles today. If you have any feedback to give me, please leave a comment, would be much appreciated and don't forget to tell your friends about this blog, thank you!

C45 Scotch Game (1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Nxd4 Qh4 5.Qd3 Nf6)

C45 Scotch Game (1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Nxd4 Qh4 5.Qd3 Nf6)

In this post I share with you all a game that was played in a tournament called 2014 August Grand Seven Fourteen III. The ongoing tournament is played at Red Hot Pawn and it started August 11th 2014. It is a 21 player tournament where all players play against each other two games and all of those games are played simultaneously. There are only two players left to fight for the win of the tournament but I can only fight for third place at the moment. Even the third place finish is still long way to go as my opponent in this game is currently third and he has finished all his games having scored 97 points, I have games still in progress and my maximum possible score is 99, which does require me to win all my remaining games. That may prove too difficult a task for me but we will see how it goes. My opponent's rating in the notation is very low but when we played our game, he was rated over 2000. For some reason or the other he started to lose his games on time. I have added today one puzzle to the following: mate in one, two, four, five and seventeen.

C41 Philidor Defence (1.e4 e5 2.Nf3 d6 3.d4 exd4 4.Nxd4 Nf6 5.Nc3 Be7 6.Be2 O-O 7.O-O a6)

C41 Philidor Defence (1.e4 e5 2.Nf3 d6 3.d4 exd4 4.Nxd4 Nf6 5.Nc3 Be7 6.Be2 O-O 7.O-O a6)

This game was played in the first round of the 2014 August Banded Quartets I 1700-1800 tournament. Our group number was 1 and it was the only group from the five groups that had five players in it. Other groups had only four players. Only the winner from each group advances and I was able to be one of the winners, so I advanced to the second round. I have added one mate in one, two mate in three, one mate in seven and one mate in eight puzzles today. Until tomorrow, my fellow chess enthusiasts!

Game number two. The game below was played in the 2014 September Grand Seven Fourteen III tournament at Red Hot Pawn. I am clinging on a very small chance of winning this tournament still but at any given time I may be out of the fight for the win as the current leader only needs to get two more points to get higher amount of points that I can gather in my remaining games.

Game number three. This one was played in a team match called "LEGENDS ARE FOREVER OPEN CHALLENGE 2016". It consists of 55 boards and it is between SHETOS and Chess School. I played on board 8 for Chess School and I was able to win both of my games against Silent_Venom. The current score in the match is 34 - 68 in favor of Chess School and therefore we have secured the win in the match quite nicely. SHETOS has lost 21 games so far on time and Chess School has lost 4 games due to timeouts.

The game below is a rather silly one in that for some reason I made my life harder by not taking the free piece on a5 after 15...f5. I do not know what was I thinking at the time or if I even was thinking at all... Sometimes my brain just goes to vacation without my permission. I was able to play reasonably well, but this could have been much easier for me had I kept my eyes open.

The only site that I know of that keeps track of the amount of moves you make is Red Hot Pawn. It is kind of nice feature actually not that the amount of moves makes all that much difference to your playing strength necessarily. I have made 8811 moves there at the moment I type this. That is only a small fraction of the moves that my opponent has done. He is one of the two very esteemed move makers at Red Hot Pawn as he and only one other player have made over one million moves on the site!! My first game against this same opponent was over ten years ago and I have at the moment a couple of games against him. The game below was played in the 2014 Grand Seven Fourteen III tournament. The tournament is played in one group of 21 players and it is a all versus all times two, so when you start the tournament you have 40 games in progress in this tournament alone. I can only fight for the third place in the tournament anymore as I have lost too many points. Well, I have theoretical chances for the second place but that would mean that I would need to win all my remaining games and the player currently second can't earn more points from the remaining games. I have added one mate in two, three mate in four and one mate in six puzzle today.

E61 King's Indian: Early deviations for White, including Smyslov System (1.d4 Nf6 2.Bf4 g6 3.Nf3 Bg7 4.e3 O-O 5.h3 b6 6.Be2 Bb7 7.O-O d6 8.c4 e6 9.Nc3 Nbd7 10.Qc2)

E61 King's Indian: Early deviations for White, including Smyslov System (1.d4 Nf6 2.Bf4 g6 3.Nf3 Bg7 4.e3 O-O 5.h3 b6 6.Be2 Bb7 7.O-O d6 8.c4 e6 9.Nc3 Nbd7 10.Qc2)

The game you see below is another one where the move order is not normal for this line. In the usual move order White plays 2.Nf3 and 3.Bf4. It happens very rarely that the computer likes my moves enough that it puts exclamation point behind one of my moves in the analysis but in this game it does do that. Exclamation point after a move indicates that the move was good if someone wondered what it means. I have also added one puzzle to the following pages: mate in ones, mate in two moves, mate in threes, mate in four moves collection and mate in 9. If you find these posts useful or have any suggestions, please leave a comment. Feedback is always appreciated, thank you all who have come to view this blog and until tomorrow, my fellow chess enthusiasts.

The game below was played during the time when I started to play more and more correspondence chess. Most games I have had in progress at the same time was earlier this year when I reached 300 simultaneous games. That did last only a few hours as some games ended but still it was a amount to reach. At the moment I have only 277 games in progress so the pressure of making moves is not as bad as it was before. I do try to get to under 100 games so that I would have more time to other things as well. The game below was played at Red Hot Pawn and it still remains one of my most active places to play, at least if the amount of games in progress is any indication, I have currently 115 games in progress there. This game is also one of the last games that were not played in a tournament, now I have only tournament games in progress there. I have added one mate in one, two mate in three, one mate in five and one mate in fourteen puzzles today. There are now 714 different puzzles published and more will be coming each day.

Here it is, ladies and gentleman, the game that raised my rating six points to get it over 2200 at Queen Alice Internet Chess Club. This game was played in invitation only private tournament called szybkielanie. It is a tournament that uses the Swiss System and has four rounds. There are fourteen players participating in this tournament. Players who participate in it are from all around the world. There are players from Argentina, Brazil, Canada, Netherlands, Portugal, Poland, Brunei, France, Spain and last but by no means least Finland of course. The game below is from the first round of the tournament between myself and Gosiulkaa. The early part of the game was not that easy for me after 11.Bg5, after that move I just tried to get out of the pin by slowly getting to a position where I can play Qd6 to free my knight. I of course missed completely my opportunity to play 20...b5 because the Queen needs to move to a square where it can't defend the d3 square, enabling me to take advantage of my opponent's clumsy rooks by playing Bd3 after the Queen has moved. Instead I just tried to play so that I can get out of the pin safely and get my Queen to d6. I was not sure how this game will end until I saw the move 27...g5, after that it was much easier to find moves than it was up to that point and the game speeded up a lot from the slow play I had played so far. I have added one more puzzle to mate in one, two, three, eighteen and nineteen puzzle pages.

C22 Centre Game (1.e4 e5 2.d4 exd4 3.Qxd4 Nc6 4.Qd1)

C22 Centre Game (1.e4 e5 2.d4 exd4 3.Qxd4 Nc6 4.Qd1)

It may have taken awhile but I did find yet another opening variation that has not been covered here before. The game below is just one of the 216 correspondence games I have played at Red Hot Pawn. I have also managed to get a bit closer again to my peak rating there, now only 9 points away. Talking about peak ratings, I did manage to get a new one at Queen Alice Internet Chess Club today as my opponent had enough of the game and resigned. Now my new peak rating there is 2201!! I thought I would never see this day when one of my ratings would go so high. I will post that milestone game tomorrow after I have analysed it. I have added one mate in one, one mate in two, one mate in six and two mate in seven puzzles today.

Game number two. The game below was played in the second round of the 2014 August Banded Threesomes I 1700-1800 tournament held at Red Hot Pawn. This is my only loss on second round and if I do not lose my last game in this round, I will win my group and advance to the third round. My last game is also the last game of the round. This game was full of mistakes on both sides but I ended up messing up the ending that at one point could have been drawn and instead I lost.
