A10 English Opening: Unusual Replies for Black (1.c4 f5 2.Nc3 Nf6 3.d3 c6 4.g3 e6 5.Bg2 d5 6.cxd5 exd5 7.Nf3 Bd6 8.O-O O-O)

A10 English Opening: Unusual Replies for Black (1.c4 f5 2.Nc3 Nf6 3.d3 c6 4.g3 e6 5.Bg2 d5 6.cxd5 exd5 7.Nf3 Bd6 8.O-O O-O)

My opponent's reply to 1.c4, 1...f5 (16401 games, score 54.2%), is the 7th most often played move in the position, according to my reference database. More common moves against 1.c4 were 1...Nf6 (142556 games, score 54.5%), 1...e5 (106650 games, score 54.1%), 1...c5 (54778 games, score 55.1%), 1...e6 (53919 games, score 54.5%), 1...g6 (32975 games, score 52.5%) and 1...c6 (30736 games, score 55.1%). The second move by me, 2.Nc3 (5760 games, score 51.2%) is the most played move, but it does not score as well as 2.g3 (4303 games, score 55.6%) and 2.Nf3 (2850 games, score 55.7%), for instance. The reply 2...Nf6 (5366 games, score 51.1%) was the most popular choice among players. I then played 3.d3 (259 games, score 52.5%), which is the 4th most often played move, only behind the moves 3.g3 (3254 games, score 52.5%), 3.d4 (913 games, score 50.1%) and 3.Nf3 (773 games, 46.7%). The reply was the rarely seen move 3...c6, only two games in the database with a 50% score. The moves 3...g6 (99 games, score 51.5%), 3...e5 (75 games, score 52%), 3...e6 (56 games, score 54.5%), 3...d6 (33 games, 53%) and 3...b6 (5 games, score 40%) have been preferred more than what my opponent played in the game. Players rated 2055 and 2061 had played the move 3...c6. Due to the rare move order, this game went to previously unseen path when I played 4.g3. The only two moves seen in that position are 4.Bg5 and 4.e3 and both moves have been played once, according to my reference database. In the game where 4.Bg5 was played, White won and in the game where 4.e3 was played, Black won the game. However, in the latter game, the player who controlled the black pieces was over 500 points higher rated than the player who controlled the white pieces.

With my 5th move, Bg2 (4 games, score 50%) the game was brought back to previously played lines. 5.Bg2 is the most played move in the position. The next move 5...d5 (26 games, score 71.2%), gave even more reference games and it was also the most often played move. The game continued with the most popular moves in the position when I replied with the move 6.cxd5 (21 games, score 61.9%). The same pattern continued with the response 6...exd5 (18 games, score 63.9%). My 7th move, Nf3 (19 games, score 68.4%), has seen play by some strong players, the highest rated of them being Normunds Miezis, who was rated 2509 at the time of the game where the move 7.Nf3 was played by the Grand Master. The next move, 7...Bd6 (27 games, score 55.6%), was also most often played move. We kept following the game Normunds Miezis (2509) - Sascha Aulich (1908), played on October 4th, 2007, up to the move 8...O-O. Both moves 8.O-O (25 games, score 58%) and 8...O-O (80 games, score 63.3%) were most often played moves in the position. Once again there is a bit of a conflict in the notation of the novelty with my reference database, since the move 9.Bg5 has been played in 11 games with a score of 59.1%. It was the 2nd most played move, only behind the move 9.e4 (77 games, score 84.4%). Then Kojjootti played 9...Qe8 (2 games, score 100%), which was the 3rd most often played move. More often the moves 9...h6 (9 games, 38.9%) and 9...Nbd7 (3 games, score 66.7%) can be seen in the database. The next move 10.Qb3 had been seen only once before and in that game the player controlling the white pieces won the game. The move 10...Kh8 is actually the real novelty that was played in this game. Previously the move 10...Nbd7 was played in that position.
