D00 1.d4 d5: Unusual lines (1.Nf3 d5 2.d4 Nf6 3.Nc3 e6 4.a3 c5 5.e3 Nc6)

The game below was played in the 2014 September Octet I 1700-1800 tournament that was held at Red Hot Pawn. I was 2nd in the final standings of this eight player tournament. I was 9 points behind, AttilaTheHorn (1684), the player who won the tournament. The first clear turning point of the game was seen when I played 10...Bd7. It was a silly move that lost a pawn because when my opponent played 11.dxc5, I could not take back with my bishop due to the reply 12.b4 and I would have been a piece down.

It was probably just best to push my pawn to c4 and control the squares d3 and b3, so that rabarber can't go either of the squares safely.

I did not have any compensation for the pawn at first and things looked a bit grim for me until rabarber played 14.g4 and gave back the pawn. After that it was mostly downhill for my opponent.

14.b4 would have protected the pawn on c5 and kept the position firmly under my opponent's control.

That being said, it was not winning for me until rabarber chose to play the awful 21.h5. It would have allowed me to win a pawn, had I played 21...Bxf4. Capturing the bishop would be inadvisable in view of the continuation 22.exf4 Qg1+ 23.Kd2 or 23.Ke2 and 23...Qg2+ winning the rook on h3. Unfortunately I missed my golden opportunity and played the far more uneventful 21...f5. It still kept my on the better side of the board, but I would need to work harder to win the game.

It was a good idea to guard the square g1 with the king by playing 21.Kf1.

Rabarber then played 22.gxf5, which opened the g-file for a possible attack towards my king. I should have replied with either 22...Bxf4 or even 22...Rxf5, but for some reason I preferred to play 22...exf5 and open the e-file. It does make some sense to open the file in front of the enemy king, but according to Stockfish 8 64 POPCNT at depth 29, it was not as strong as the aforementioned moves and actually gave a chance for my opponent to save the game. Fight for the draw could have started with the move 23.c4. Alas, rabarber moved his or hers queen to g2 my opponent's position went down the drain. It was mistake from which rabarber could not recover from and I ended up winning the game due to my opponent's resignation after 39...Rxb4 in a position where I was up three pawns.
