A36 Symmetrical English vs ...g6: 4.Bg2 Bg7 (1.c4 c5 2.g3 g6 3.Bg2 Bg7 4.Nc3 Nc6 5.d3 a6 6.a4 Nf6 7.e4 O-O 8.Nge2 Ne8 9.O-O)

With the game I shared yesterday, there did not seem to be that much difference in my move accuracy between my blitz and correspondence games, but then again correspondence games have been for some time blitz games for me that take weeks, months or sometimes years for me to complete... This is an over the board game that I played nearly a decade ago and it has been in the blog before under a different post. The move 1.c4 (128079 games, result 56%, Elo-average 2440) is the 4th most common first move in the LiveBook. More often seen moves are the usual 1.e4 (809460 games, result 54%, Elo-average 2422), 1.d4 (663001 games, result 55%, Elo-average 2438) and 1.Nf3 (192202 games, result 55%, Elo-average 2438). My reply 1...c5 (15744 games, result 56%, Elo-average 2426) was the 4th most often occurred move. More played moves were 1...Nf6 (36108 games, result 57%, Elo-average 2415), 1...e5 (27486 games, result 53%, Elo-average 2432) and 1...e6 (19078 games, result 56%, Elo-average 2429).

Then my opponent played 2.g3 (3598 games, result 54%, Elo-average 2424), which is the third most played move in the LiveBook. More popular moves have been 2.Nf3 (22365 games, result 56%, Elo-average 2454) and 2.Nc3 (4534 games, result 52%, Elo-average 2410). My reply 2...g6 (1686 games, result 53%, Elo-average 2434) was the first move in this game that was the most popular alternative. The next move by my opponent, 3.Bg2 (1768 games, result 53%, Elo-average 2436), was the natural continuation to 2.g3. I continued to copy my opponent's moves as I made my move 3...Bg7 (2693 games, result 51%, Elo-average 2434) and it was, not surprisingly, the most often occurred move in the position. The game then continued with the most played moves 4.Nc3 (4074 games, result 50%, Elo-average 2422) and 4...Nc6 (6679 games, result 51%, Elo-average 2427). My opponent then chose the move 5.d3 (768 games, result 53%, Elo-average 2415), which is the 5th most popular move. More popular moves have been 5.Nf3 (5193 games, result 49%, Elo-average 2409), 5.a3 (1589 games, result 53%, Elo-average 2435), 5.e3 (1355 games, result 49%, Elo-average 2411) and 5.e4 (862 games, result 44%, Elo-average 2354). I then went for the rather rarely seen move 5...a6 (31 games, result 53%, Elo-average 2416), which is the 5th most played move. 5...d6 (290 games, result 55%, Elo-average 2407), 5...e6 (274 games, result 52%, Elo-average 2424), 5...Nf6 (125 games, result 54%, Elo-average 2427) and 5...e5 (74 games, result 53%, Elo-average 2374) are more often played moves than what I played in the game.

Next my opponent decided to play 6.a4 (2 games, result 75%, Elo-average 2467) with the idea of preventing me from playing b5. Slightly less rare moves were 6.e4 (15 games, result 40%, Elo-average 2350), 6.Nf3 (14 games, result 32%, Elo-average 2377) and 6.h4 (5 games, result 90%, Elo-average 2460). In both of those games Black replied with 6...Nf6 and I chose to play it in this game as well. Then in both games White played 7.e4, the same move that was also played in my game. With the move 7.e4, the amount of reference games went up to 4. In two games Black played 7...O-O (result 75%, Elo-average 2420), like in this game. In the other two games the moves 7...Rb8 (result 0%, Elo-average 2420) and 7...d6 (result 0%, Elo-average 2489) were played. The game continued with the natural developing move 8.Nge2 (11 games, result 55%, Elo-average 2432), which also prepared 9.O-O. I then played the move 8...Ne8 (3 games, result 50%, Elo-average 2541) with idea of relocating the knight to c7 so that the knight can support the advance b5. It was the second most played move, only behind the move 8...d6 (8 games, result 44%, Elo-average 2476). The last move that is included in this opening line according to Fritz 16's Classify Opening feature, 9.O-O, was played in 3 games in the LiveBook. I continued the game with 9...Nc7 (3 games, result 0%, Elo-average 2370), which was the rarest move that had been played in the position. The other two moves that had been seen in the position were 9...d6 (10 games, result 60%, Elo-average 2408) and 9...Rb8 (4 games, result 25%, Elo-average 2455). With the move 10.Nd5 we went out of played lines, at least according to the LiveBook. The moves that had been played in that position are 10.Be3 (2 games, result 0%, Elo-average 2328) and 10.d4 (1 game, result 50%, Elo-average 2247). This game was only example of the times where I have accepted a draw in a winning position because I have not seen the win during the game...

This time there is only one game that I was able to find where both players were reasonably high rated.
