C54 Giuoco Piano: 4.c3 Nf6, main lines with 5.d4 and 5.d3 (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.O-O d6 5.h3 Nf6 6.Re1 O-O 7.c3 Be6 8.Bxe6 fxe6 9.d4)

This one was played in a tournament called 2014 September Grand Seven Fourteen III at Red Hot Pawn. I was 4th in the final standings and I managed to gather 99 points in 40 games. A player called kopsov (1858) won the tournament. Kopsov gathered 114 points. The first position to look at came after my move 22...Rxd5. I had just won a pawn, but maybe my opponent had some compensation for the pawn, mainly the better placed bishop. It was not that easy to get that extra pawn matter that much because my pieces were not well placed to support the advancement of the pawns.

23.a5 was a better choice than 23.f3, the move that Thaba played in the game.

Thaba played 23.f3, which I guess was played in order to improve the control over the square e4, but it does weaken the pawn cover in front of the king a bit. It was not the best move, but neither was the move that I played in reply, 23...Bc5. I played it so that I can get rid of my bishop and so that I can get my rook to the c-file, which I thought was the right idea. The bishop trade did indeed happen and my rook did get to c5, but since my rook on f5 was still out of play, Thaba did have quite good compensation for the pawn. I did manage to eventually improve my position and get my extra pawn become dangerous asset, but the result of the game was not clear before my opponent made the final blunder 36.Rxd7.

It was necessary to keep both rooks in play and generate some threats with 36.Ra6.

Trading the rooks was a huge mistake because it made winning the game much more simpler for me. Removing the more active of Thaba's rooks meant that there really was no counterplay possibilities left for my opponent. It would have been rather easy to convert the advantage into a win, but my opponent made it even easier by moving the king to f2 on move 37. I was given the choice of winning either the pawn on a4 or the one at h4. I decided that the more important pawn to take was the a-pawn, because then my queenside pawns can easily decide the game. Losing the second pawn was enough for Thaba to resign.
