D00 1.d4 d5: Unusual lines (1.d4 Nf6 2.Nf3 d5 3.Nc3 g6)

The game I am sharing today was played in a team match called Khamûl the Nazgûl at Chess.com. It was played on 17 boards between Lord Of The Rings and Cafe Jasmin - Open 24/7. I played on board 3 for Lord Of The Rings and I was able to win both of my games against my lower rated opponent. Lord Of The Rings was able to win the match with a score of 24.5 - 9.5. The first sign of trouble for nikdelhossein was when my opponent played 7.O-O. Unfortunately I did not find the move 7...Nxe5, which would have given me the initiative. The game might have continued 8.dxe5 Ng4 and now 9.f4 should not be played in view of very nasty move Qb6+. Therefore the move 9.e4 is much better.

I simply castled in the game, which should not have posed problems for my opponent, but nikdelhossein took another wrong turn with the move 8.a4. It was a better idea to just play 8.f4, so that if I were to take on e5, my opponent could take back with the f-pawn. I then took on e5 and when my opponent took back, I retreated with my knight to d7, which was not at all the correct idea. I needed to play 9...Ng4 in order to seize the advantage. My knight retreat equalized the position, but things started to go wrong again for nikdelhossein with the move 11.e6.

Moving the pawn to e6 loses the pawn by force, there is no way to protect the pawn sufficiently and therefore nikdelhossein should have gone for the counterattack with 12.e4 in reply to 11...Nc5. My opponent played 12.b4 instead and allowed me to take the pawn on e6 without any real resistance. I was not able to keep my advantage for a long time, since already with my 13th move d4, I threw most of my advantage away. Nikdelhossein should have played 14.Ne2 in order to take advantage of my mistake, but my opponent chose to play 14.exd4 instead and I replied by taking the pawn on d4 with my queen.

It forced the queen trade and everything seemed to go my way. For a few moves I was able to indeed play quite good moves, but then on move 20 I made a huge blunder cxb5. It would have allowed the knight to jump to d5 and my opponent would have had able counterplay for the lost material. Luckily for me, nikdelhossein played 21.Bxd6, which was much more easily dealt with than 21.Nd5 would have been. Up to the move 25.Kf1 I was on a clearly better side of the board, but then I played 25...a6 and the game was closer to a draw than one of the players winning the game again.

I played 25...a6, so that I could move my rook from a8, but alas it allowed the knight fork at c7, and my opponent could have won the pawn back from d5. For some reason nikdelhossein did not want to take back material, but moved the knight to e6 after Rac8. Both moves should be playable, but I would have gone for the material had I been the one controlling the white pieces. The game went downhill again for my opponent when nikdelhossein played 28.Nxg7.

A few moves later I messed up again and moved my king to f6 on move 31. I moved my king to f6 in order to protect my d-pawn. The problem with my move was that nikdelhossein could have replied with 32.Rb4 and the pressure against my b-pawn makes my progress in the position really difficult and my opponent does have enough compensation for the material at that point.

Nikdelhossein played 32.c4 in the game, which was the first of two consecutive blunders that my opponent made and caused my opponent's loss. For some reason the engine likes the move 32...Ke7 in reply and considers the position to be won for me. To me, it seemed more logical to go to e6 with the king and support the d-pawn. Then my opponent exchanged pawns, which was my opponent's final mistake, from which there was no coming back. My opponent continued the resistance up to the move 53...h3, after which nikdelhossein resigned.
