E12 Queen's Indian: Unusual White 4th moves, 4.a3, 4.Nc3 Bb7 5.a3 and 4.Nc3 Bb7 (1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Nf3 Be7 5.Bg5 O-O 6.e3 Nbd7 7.Bd3 dxc4 8.Bxc4 b6 9.O-O Bb7)

This was played in the first round of Rilton Cup Open in 2003. My first tournament abroad and I managed to start with a win, so all looked good at this time. This was played in a time when I had increased my rating over 300 points in a year and almost every time I played in a team match or in a tournament I was able to get my rating higher. Only in one team match during that year, I lost and therefore stained my otherwise positive score. This ended up being slightly positive tournament for me as ratings are concerned, but as I did not play on all the rounds, it was a bit of a shame to go all the way to Stockholm to play a tournament and not to play on all the rounds.

D00 1.d4 d5: Unusual lines (1.d4 Nf6 2.e3 d5 3.f4)

This one was played on the first round of the 2014 October Glacial Super Casual Banded I 1650+ tournament. The tournament started on November 3rd 2014 and it was held at Red Hot Pawn. All the 22 games that I needed to play in group 1 started on that day. I was not able to get that many points in group 1 and I was on 4th place in the final standings. Veca was 6th in the final standings of the group.

Despite the rating difference and the material advantage I was able to get in the game, this game was far from easy for me and at times it seemed that my sometimes sloppy play would throw away my winning chances. I started to be worried a bit after my opponent played 34.Qg2, which threatened to invade my position with the queen. My winning chances seemed to evaporate especially after 39.Bf7 because I started to lose some pawns. I think that the losing move was 43.Nf7 because after my reply 43...Qb7 I can finally relax and push my a-pawn, after the trade of queens that is.

Game number two. This game was played on the seventh round of the Easter tournament that was played at Helsinki in 2008. By winning this game, my gathered points increased to 3. That result was a slightly positive one and my selo rating increased by 5 points. I was 27th in the final standings in a group that had 40 players.

Already on move 2, my opponent makes a questionable decision by playing f4. It is at least a minor inaccuracy if not a clear mistake. 2.c4 or 2.Nf3 are clearly better alternatives. My opponent keeps playing with only pawns and after 4.g3, I should have a small advantage on my side. The odd moves continue from my opponent and only some inaccuracies by me make the game even a bit. After 9.Qb6 position should be roughly equal. My opponent decided to reply with 10.Bxc6+, which I was happy about because now the better one of White's bishops is traded to my knight. Also the fact that I now have the bishop pair, should give me a small advantage. My opponent went further down the drain with the move 12.Qb3, but because I was not able to find a good reply and instead played 12.c4, I was only slightly better. After 14...O-O-O the game is balanced once again. However, my opponent blundered with his next move and played 15.h4. That move could have been the losing move, but again I was not able to take full advantage of my opponent's mistakes. My move 15...h6 was good enough for a clear advantage though. A few moves later I played a sloppy move 19...Bxh4, after which some of my advantage disappears. On his 25th move, my opponent goes from slight disadvantage to a clear disadvantage and any hope for a draw was gone.

D00 1.d4 d5: Unusual lines (1.d4 Nf6 2.e3 d5 3.f4 c5 4.c3 e6 5.Nf3 Nc6)

This somewhat disappointing draw, as far as the ratings are concerned that is, was played at Red Hot Pawn in a tournament called 2014 September Grand Seven Fourteen III. This was a hard fought game and draw is the right outcome of the game. At some points I even thought that I was on the worse side, so I can't maybe feel that bad that the game ended like it did. I was fourth in the final standings of the tournament and gathered 99 points in 40 games. The winner, a player called kopsov (1877), gathered 114 points. The second place went to Reverb (1782), who gathered 104 points. A player called Luft (2006) finished the tournament on third place with 102 points. Below is some of the move statistics from LiveBook.

Game number two. This was played on the first round of the 2014 October Long Haul Split I tournament that was held at Red Hot Pawn. My game against veca was the last game I had in progress and the result of this game determined the winner of group 2. By winning, I secured my place on the second and what could have been the last round, where I faced caissad4 and because we both won with the black pieces, the winner of the tournament was determined on round 3. Both caissad4 and me won our groups with 59 points that we were able to gather in 22 games. Caissad4 won group 1 with a 8 point difference, while I was only barely able to win my group, because beatlemania (1715), the player who finished second in the group gathered 58 points. On the third round I drew with caissad4 when I was playing with the white pieces and lost with Black, so caissad4 ended up winning the tournament. As you may see in the statistics, the move order used in the first game is better for Black than the move order used in this game.

C62 Spanish Game: Steinitz Defence (1.e4 e5 2.Nf3 d6 3.d4 exd4 4.Qxd4 Nc6 5.Bb5 Bd7 6.Bxc6 Bxc6 7.Nc3 Nf6 8.Bg5 Be7 9.O-O-O O-O 10.Rhe1 Nd7)

This is the 32nd game in the 100 15 minute games match between two friends. With this win I was able to increase my lead in the match, but the match was not even close to be decided one way or the other. The score was 17 - 15 in my favor after this game. This may be one of the most tactically precise games that I have ever played, at least based on the precision percentage 87, determined by the analysis! If only I could get that in every game... Then my rating would be much higher than it is now.

A03 Bird's Opening with 1...d5 (1.f4 d5 2.Nf3 c5 3.d3 Nc6 4.g3 Nf6 5.Bg2 g6 6.O-O Bg7)

The game I am sharing today is the 28th blitz game that I played in 2016 at Chess.com in a series of 106 games that I played against Kojjootti. After this game the score was 18.5 - 9.5 in my favor. The move 7.Re1 was the first one that had not been played in the games that appear in the LiveBook. The moves that had seen some play are 7.Nc3 (103 games, result 52%, Elo-average 2392), 7.c3 (91 games, result 46%, Elo-average 2375), 7.Qe1 (67 games, result 54%, Elo-average 2413), 7.e3 (4 games, result 50%, Elo-average 2396), 7.h3 (3 games, result 33%, Elo-average 2386), 7.Kh1 (1 game, result 100%, Elo-average 2300), 7.d4 (1 game, result 50%, Elo-average 2495), 7.a3 (1 game, result 0%, Elo-average 2104), 7.Nbd2 (1 game, result 0%, Elo-average 2302) and 7.Na3 (1 game, result 0%, Elo-average 2351). According to my reference database, the move 7.Re1 had been played two times before this game. The next move 7...O-O was also played in both games. The 8th move e4 is a novelty. Previously the moves 8.Nbd2, 8.c3 and 8.a4 had been played.

A38 Symmetrical English vs ...g6: 4.Bg2 Bg7 5.Nf3 Nf6 (1.c4 c5 2.Nc3 g6 3.g3 Bg7 4.Bg2 Nc6 5.Nf3 Nf6 6.O-O O-O 7.d3 d5 8.cxd5 Nxd5 9.Nxd5 Qxd5 10.Ng5 Qd6 11.Ne4)

The full opening line could not be found in the LiveBook. I think this was the second time it has happened in the analysis of my games. This is the 26th game in my series of 106 games that I played in 2016 at Chess.com. This quick loss meant that the score was 17 - 9 in my favor after the game. After my huge blunder 11...Qd5 and seeing the reply 12.Nf6+, there was no point of continuing the game, so I resigned.

B18 Classical Caro-Kann: 4...Bf5 sidelines (1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Bf5 5.Ng3 Bg6 6.f4)

This is the 25th game in the series of 106 blitz games I played against Kojjootti at Chess.com. With this win I increased my lead so that the score was at this point 17 - 8. This is one of the rare games where the precision of the players is not shown, it is likely due to the fact that the game was pretty much decided on move 6 when my opponent played 6...f6.

D10 Slav Defence: 3.cxd5 (without early Nf3) and 3.Nc3 (1.d4 Nf6 2.e3 d5 3.c4 c6)

This game was played at Red Hot Pawn and is the last one from 2008. Well, the last game I played in that site that year anyway. This game featured many mistakes but luckily for me, my opponent made worse mistakes than I did. I have shared this game before, but not with the tactical analysis. To be honest, the most interesting thing I personally look after the analysis is done, is the precision percentages. It varies quite a lot in my games and it may be a good way to know whether or not the game was well played. According to the percentages in this game, both players had a lot of room to improve their game.

A03 Bird's Opening with 1...d5 (1.d4 Nf6 2.e3 d5 3.f4 Bf5 4.Nf3 c5)

This was played in the 2014 September Octet I 1700-1800 tournament at Red Hot Pawn. This game and my other game against veca were the longest lasting games of the tournament. Only thing that was at stake on those games was the second place in the tournament, which I got by winning both of my games against veca. But as only the winners of these tournaments are remembered, it did not matter all that much. The main thing I care about usually is that my rating keeps increasing, winning the tournaments would be just an added bonus, which I have been able to do in one tournament at Red Hot Pawn so far. The game below is one of the better games I have played at Red Hot Pawn, even though this was not played all that accurately by me. Then again I did not do any huge blunders.

A36 Symmetrical English vs ...g6: 4.Bg2 Bg7 (1.c4 c5 2.Nc3 g6 3.g3 Bg7 4.Bg2 Nc6 5.e3 d6 6.Nge2 Bg4)

This was played in the first round of an over the board tournament that was held at Turku between December 7th 2001 and December 9th 2001. My rating back then was really low and I did not know all that much about chess. I am not sure how many times I faced this opponent, but he has always been a difficult adversary for me over the board. We both have improved our play over the years and if we were to play 100 game match or something like that I would not be so sure of the result. I think I would have good chances against him, based on mostly of the fact that I think I have spend a lot more time studying the game lately than he is, but he may still have the upper hand. Back in 2001, I did continue the games much longer than I would continue these days. I mean I would have resigned this game much sooner if this were a more recent game.

A34 Symmetrical English: 2.Nc3, lines with ...d5 (1.c4 c5 2.Nc3 g6 3.e4 Bg7 4.f4 Nc6 5.Nf3 d6 6.d3 Nf6)

Still continuing with my blitz games, this is the 24th game in the series of 106 games and after this game the score was in my favor 16 - 8. One notable feature in these games is that the same opening variation is not easily repeated. I am not actually sure if all the 24 games have featured a different opening, but I would not be surprised if they did. In situations where I know that I will be playing multiple games against the same opponent, I am knowingly changing my approach to the games. I have played a few 100 game matches against a couple of my friends and I have had good success with my approach. Also it would be really boring to play the same opening all the time, though it would help the player to understand the positions that come out of it. That being said, even if I try to go for the same opening all the time, I am rarely successful in my attempt to do so. This may be due to the fact that I rarely play against the same opponent multiple times, unless I am playing a match against that player. Well, it is true with my online games, but not with over the board games, at least when it comes to the games I have played at my local chess club where I have played several hundred blitz games against the people who usually go there.

A01 Nimzowitsch-Larsen Opening (1.b3 d5 2.Bb2 Nf6 3.g3)

This is the 23rd game of the 106 blitz games that I played between July 15th, 2016 and August 2nd, 2016. They were the only blitz games I played at Chess.com that year and I have not played blitz there since. I might play blitz there again at some point, but I have not been that interested of doing it for a long time. All of those 106 games were played against the same opponent and at this point the score was 15 - 8 in my favor. First of those 106 games was my first one after an almost two year break from blitz at Chess.com. The below statistics are taken from the LiveBook.

E38 Nimzo-Indian: Classical, 4...c5 (1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 c5 5.a3 cxd4)

I think this was the first time when not all of the opening moves were found in the LiveBook. The move 5...cxd4 had not been played at all. In my reference database the move 5...cxd4 had been played in 44 games and it had a score of 51.1%. The moves 5...Bxc3+ and 5...Qa5 were more often played and they were also more successful for the player controlling the black pieces. We followed previously played moves up to the move 7...O-O. Three games had reached that position and in two of them the move 8.e4 was played. One player had chosen to play 8.Bg5.
