It was a second round in the Monday’s club and I got my nemesis – the guy I lost to quite a few times. Is it psychological or his style of play or openings that I didn’t master yet – probably all of it. Unexpectedly I got Black again, so Queen’s Indian.
What I am still missing playing this opening is a clear understanding of the ideas for Black. 5… d5 was not a good move, instead 5… Bb4 6. Nf3 Ne4 7. Qc2 O-O 8. Bd3 f5 9. O-O Bxc3 10. bxc3 d6 was a way to go. Another positional misstep was 8… exd5 instead of 8… Nxd5 9. Nxd5 Bxd5. You should not close the diagonal for the bishop. Then 10… cxd4 gave him ~0.8 advantage, I had to play 10… Nc6.
Then I missed an opportunity with 12… Nxd4. Of course, I saw 13. Bxh7+ and decided that it was not worth to take the pawn, that it would weaken my kingside. But the position was equal. 12… Rc8 was just bad because of Bf5. He pressured and won the “d” pawn.
Eventually we exchanged most of the pieces and went into a rook endgame. Suddenly he started to play not that well as before, maybe rook endgame is his weakness. It happened once in the past when I missed a chance to win a rook endgame with one strike. He played 33. a4, I saw the answer before and played Rd4. If he instead of that would play 33. b3 then my idea wouldn’t work.
I put my rook behind his pawn according to Tarrasch and everything was fine until move 45, when his king’s movement towards the “b” pawn got me worried and I made that horrible move Kd7 losing the game. The rest is self-explanatory, he just demonstrated some technique.
When I was driving home, I thought what could I do differently and suddenly realized that I did not have to move the king. If his king would approach the “b” pawn, the rook would give checks and the king had nowhere to hide. This all is because the pawn was advanced to b7. The funny thing is he did not realize that either.
The right way was to advance the pawn only to b6 and then move the king, still it’s a draw in this case.
