E32 Nimzo-Indian: Classical (4.Qc2): 4...0-0 (1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 O-O 5.a3 Bxc3+ 6.Qxc3 b6 7.b4)

The game you see below was played in a tournament called AUTO-OPEN-3254 and that tournament is held at the Queen Alice Internet Chess Club. It has been maybe the only correspondence chess site where my rating has gone steadily upward and I have only suffered only momentary rating losses. The first round of this tournament is still going even though it would not be if the players who could claim a win on time, would actually claim their wins. Those four games that are still going needlessly do not even have any effect on who advances to the next round as that is already decided. The 20 players that are on the tournament are divided into five groups of four players. And I believe only the winner advances into the next round. As there can be only maximum of six simultaneous games, in the next round there will be one group of three people and one group where there are only two players. The winners of round two will face off in the final third round. No matter what happens in the two remaining games of my group, I will be able to advance to the next round as I have secured my win in the group already. Not sure if those games will ever finish though... With the win in this game I was able to increase my rating to 2169. I have added ten more puzzles today divided in mate in two, three and four pages.
