Zapata vs Chambers after 14…h5 with white to play

After a quick run through of the game the decision was made to input the moves into 365Chess while simultaneously inputting the moves into the analysis program at The thought was that I would just blow right on by the opening moves, but after inputting the first two moves this former player was ASTOUNDED to see the SF program does NOT play 3 d4!!! I kid you not. Stockfish shows the best third move for white being 3 c3, a move with 6246 games in the database. There are 115884 games in which 3 d4 has been played. Amazin’… SF plays 4…Nf6 in lieu of the 4…e5 move in the game. 6…Be7 has been played in 2194 games, but SF will play 6…a6, which has been played in only 278 games. The move 7 N1c3 has been played in 1370 games, but SF will retreat the knight with 7 N5c3, as have only 52 intrepid souls… SF would not play 7…a6, as has been seen in 1362 games, but instead play 7…Nf6, as have only four other enlightened players. SF will play the most often played move, 9 exf5, rather than the seldom played 9 Bd3, which, according to SF, loses the advantage. 10 g3 is rather confrontational, and it has been the most often played move, but SF will bring the knight back to c2, as have 15 other players. Now we come to a point where 20 other players have played the move played in the game, 10…Nf6. Five players have opted for 10…fxg3. The Stockfish program at will play 10…Nh6, which will be a Theoretical Novelty as soon as some human makes the move. Now taking the pawn with gxf4 is the correct way to play, which is exactly how the Discman played. Zapata took the pawn with 11…exf4, but, and you knew it was coming, SF would have played 11..Bg4, attacking the Queen. This is something I’ve seen much of when replaying, and annotating, games. The SF program will attack a more valuable piece just about any time it gets a chance to do so. At this point in the game the Discman played his knight to g4 with his 13th move, as did 7 other players. Two players chose other moves, and one of them was Seth Homa:

After 14 f4 in the Zapata v Chambers game Stockfish prefers 14…Bh4. Chris played the much inferior 14…h5, after which SF shows the Zapper with an advantage of +1.6, which means a Grandmaster should win from here. Instead, Zapata played 15 h4, after which SF shows the game even at 0.0.
