Today I hit another milestone in the history of this blog, I posted the 1300th analysed chess game!! The game below is actually game number 1301 to be featured here. Even though every week that amount increases faster than I finish games, I should not run out of games to post for a long time because I am intending to go through all the games I have notation for sooner or later and that means maybe 2000 - 3000 games I have not yet posted. The current amount of 1301 games feature 758 (58.26%) wins, 128 (9.84%) draws and 415 (31.9%) losses. There has also been 474 different opening variations seen in those games. The most featured opening is A20 English Opening: King's English Variation. General with 47 games. The reason for that is of course that I played the English Opening mainly for several years and did not really know more theoretical variations. The most successful opening that I have played in these 1301 more than at least 10 times is C41 Philidor Defense with 10 games and winning percentage of 100. My worst opening that I have played at least on 10 occasions in these 1301 games is B92 Sicilian Defense: Najdorf Variation. Opocensky Variation if I look at my losing percentages and for that opening it is 47.06. My lowest winning percentage in the openings that I have played at least 10 times in games that have been published in this blog is C34 King's Gambit: Accepted. Fischer Defense with a winning percentage of 35. Because C34 King's Gambit: Accepted. Fischer Defense also has a very high losing percentage 45, it is the worst opening for me to play. It is good to see from time to time what openings I have done well at and what are the more problematic ones for me, so that I know what to play in my future games.

The game below was played on the fourth round of a weekend tournament that was held at Salo between November 3rd and November 4th, 2007. On the first two rounds I was able to win my games, but then on the third round I suffered my first loss. Unfortunately this fourth round game added to the losses I have suffered, making my performance in the tournament more like meh than good. On the fifth round I was able to win again, so this tournament did end up going slightly positive for me. With three points I finished third in group E and due to this result my rating increased by 37 points. It was nice to get finally a positive score in a chess tournament, since it did not happen even once in 2006.

The game below went in a reasonably evenish manner until my opponent made a huge blunder 13...Rac8. It could have been the losing move, but I was not able to take full advantage of the situation. Or rather I was able to play accurately first, but then on move 19 I make a very bad decision which takes away my advantage. However, Keijo blunders with 20...Ng4 and I am on the better side of the board again. The game went well for me until I played 26.Nf3 and the position was quite even again. The bigger problem for me, actually the game losing one, is created by the move 27.Qf4. After that it did not take long until I had to resign.
