D12 Slav Defence, 3.Nf3 Nf6 4.e3 Bf5 (1.d4 Nf6 2.e3 d5 3.c4 c6 4.Nf3 Bf5 5.Nc3 Nbd7 6.Be2 e6 7.O-O Bd6 8.a3)

This was played at GameKnot in the "atadros's mini-tournament V". 11 players took part in this mini-tournament and I was 9th in the final standings with 5.5 points. My opponent in this game, rayfisher, was able to get 1 point and he was on 11th place in the final standings. This mini-tournament started on December 10th, 2015 and ended on October 3rd, 2016.

The first position of interest can be seen below. In that position rayfisher played 11.cxd5, which is a mistake. It was better to play the bishop to d3. The problem with the move played in the game is that when I take back with my e-pawn, I have the square e4 under my control. Had rayfisher played 11.Bd3, then I might have played 11...dxc4 in reply and that position would be more comfortable for White than the game continuation.

Rayfisher should have played 11.Bd3.

This was only the start of the problems that rayfisher faced. After 11...exd5 rayfisher made his position even worse by playing 12.Bd3. While maybe not huge blunders by themselves, these two mistakes might be considered as one blunder in the sense that they both contributed for rayfisher's position getting clearly worse. The game continued with the moves 12...Ne4 13.Qc2. With my 13th move, Qe7, I lost some of my advantage. The move 13...Re8 was the correct reply to Qc2. The game went on rather evenly until rayfisher chose to play 19.fxe4 in the position below.

19.Nxe4 seems to be the best way to capture the pawn on e4.

It was the starting point for the final downhill for my opponent in this game. It was a much better idea to play 19.Nxe4. I replied with the best move 19...Rad8 and then rayfisher played 20.e5? After that horrible move it was clear who was going to win the game. The pawn might have forked the bishop and the knight, but it was not a dangerous fork because I was able to play 20...Bxe5! Had the pawn taken back, then the rook takes the undefended queen on d3. In the game rayfisher took on e5 with the rook, but it did not matter, I could just take the rook with my queen! If pawn takes queen, then rook takes queen and I end up a pawn and an exchange up. The game ended shortly after this, when it came time for rayfisher to play his 24th move, he resigned instead of making a move.
