C64 Spanish Game: Classical Defence (3...Bc5) except 4.O-O Nf6 (1.e4 e5 2.Nf3 Nc6 3.Bb5 Bc5 4.O-O Nge7 5.Nc3)

The game below was played in the 2014 August Grand Seven Fourteen II tournament that was held at Red Hot Pawn. This is still the most successful tournament I have played at the site and I think my next tournament win there if there ever will be a second one, will be far in the future. With the way I play these days, I am not that confident of my abilities to win a game or even a tournament. That being said, my results have been a bit better lately in correspondence chess, though it may be only due to the fact that my opponents have been lower rated on average compared to the time not so long ago when I lost almost every game.

While some inaccurate moves were played before the move 11.c4, it is the 11th move by my opponent that made a real weakness in Diapason's position. Moving the pawn to c4 allowed me to control the square d4 dominantly. The move hardly lost the game, but it made playing the game more difficult for my opponent.

The c-pawn's advance was a good idea, unfortunately for my opponent, Diapason went one square too far with it.

The game went further down the drain for Diapason, when my opponent played 15.d3. After that move the engine thinks that White is quite lost or at least very close to being lost. The strongest reply seems to be 15...Bh5, though I would prefer 15...Qf7 with the idea of increasing the pressure towards White's pinned knight and perhaps winning some material as well.

The only move that would have kept my opponent's hope of a draw alive was 15.c5.

Diaposon's position quickly fell apart completely, the clearest losing blunder being 17.g3, after which it was crystal clear that I was on my way to win the game, which I was able to do by checkmating my opponent on move 20.
