E01 Catalan: Early deviations (1.Nf3 f5 2.g3 Nf6 3.Bg2 c6 4.d4 d5 5.O-O e6 6.Nbd2 Bd6 7.c4 O-O 8.b3 Nbd7 9.Bb2 Ne4 10.Ne5)

E01 Catalan: Early deviations (1.Nf3 f5 2.g3 Nf6 3.Bg2 c6 4.d4 d5 5.O-O e6 6.Nbd2 Bd6 7.c4 O-O 8.b3 Nbd7 9.Bb2 Ne4 10.Ne5)

The first move by my opponent, 1...f5 (17832 games, score 55%), was the 5th most common reply to 1.Nf3. More common moves were 1...Nf6 (239780 games, score 55.7%), 1...d5 (143901 games, score 55.6%), 1...c5 (59809 games, score 53.6%) and 1...g6 (28633 games, score 53.2%). Then I played 2.g3 (5810 games, score 58.1%), which was the most popular move played in the position. Kojjootti's next move 2...Nf6 (5146 games, score 58.3%) was also the most often tried move. The game continued with another most often played move 3.Bg2 (4784 games, score 58.8%). The next move was the rather rarely seen 3...c6 (26 games, score 67.3%), it was the 6th most played move in the position. The moves 3...g6 (2857 games, score 57.5%), 3...e6 (1079 games, score 63.3%), 3...d6 (847 games, score 57.2%), 3...d5 (57 games, score 61.4%) and 3...Nc6 (47 games, 60.6%) were more often played than 3...c6. My 4th move, d4 (2 games, score 100%), was the rarest move that has been played in the position. 4.O-O (25 games, score 68%), 4.c4 (4 games, score 62.5%) and 4.d3 (4 games, score 75%) are the other moves seen in the position.

The next move that appeared on the board was 4...d5 (9 games, score 75%), which is the 4th most common move in the position. More common are the moves 4...d6 (45 games, score 68.9%), 4...g6 (37 games, score 55.4%) and 4...e6 (20 games, score 72.5%). With the move 5.O-O (47 games, score 62.8%) the game followed the most often played line once again. The reply 5...e6 (45 games, score 64.4.%) continued to be most popular move in the position. I then played 6.Nbd2 (51 games, score 56.9%), which was the 3rd most often played move. More popular moves were 6.c4 (366 games, score 62.2%) and 6.b3 (188 games, score 64.4%). The next move, 6...Bd6 (48 games, score 58.3%), is the most played move in the position, according to my reference database. Same was true with my 7th move, c4 (34 games, score 48.5%). The next move 7...O-O (498 games, score 57.9%) also followed the most often played line. Players such as Yi Wei (2734), Michal Krasenkow (2661), Pavel V Tregubov (2642) and Vladimir Burmakin (2627), for instance, have played the move 7...O-O in their games. The following move, 8.b3 (227 games, score 52.4%), is the most often occurred move and strong players like Alexander G Beliavsky (2649), Evgeny Postny (2642), Yuri Vovk (2628) and Alexander Graf (2613) have played the move.

8...Nbd7 (79 games, score 57%) is the most popular move as a reply to 8.b3. My next move 9.Bb2 (156 games, score 52.6%) is the most natural move in the position and therefore it is no surprise that it was the most often played move. It has been played by strong players such as Ruslan Ponomariov (2756), Alexander G Beliavsky (2649), Yuri Vovk (2628) and Zdenko Kozul (2619). The reply 9...Ne4 (130 games, score 53.1%) was the most popular move in the position. The same goes for the move 10.Ne5 (117 games, score 54.3%). And for the reply 10...Nxe5 (47 games, score 51.1%). Not a huge surprise that taking back the knight with 11.dxe5 (47 games, score 51.1%) is the only move played in the position. The next move, 11...Be7 (4 games, score 75%), is the second most played move, only behind the more active 11...Bc5 (35 games, score 50%). Once again it says in the notation prematurely that the move 12.Qc2 is a novelty, when it is not a novelty as it had been played once before this game. That game found in the reference database was a short draw in which Black's 12th move was b6. Therefore the real novelty was the move 12...g5 played by my opponent.
