It is about two games – one was hard, another was easy. There were kind of opposite one to another, from the opening to the endgame, so it is interesting to compare.
Game 1 – I played on Monday, top section, expert. I lost to him once before, missed a crazy computer sacrifice with a win. I had Black, decided to play something different from Semi-Slav and chose to return to Queen’s Indian Accelerated.
In the opening I felt rather good, my isolated pawn was compensated by a good play in the center. Computer criticizes his 16. Nb3, giving the line 16…Rxc1 17. Rxc1 Ng4 18. Rf1 with ~-0.5 advantage. Then it got complicated after me deciding to get hanging pawns. I was distracted by his threat Bh3 after Ng5 and reacted to it, not seeing 20…c4! forcing his queen to b1 and then 21… Rc5 22. Bh3 Qc7 with initiative and 0.5 advantage. 24… c4 was already not a good move. I knew that I should advance one of the pawns only if it gives something to me, but I was just feeling pressure. The same was with g5, not a good move too. 35… Bb7 was a losing mistake, then I didn’t see 39. Qe5 and the rest is self-explanatory.
Game 2 – it was played in three days, in another club. I had this opponent recently, a man rated 1825 and won with a piece sacrifice. I got Black again and we played the same line of Queen’s Pawn, except I didn’t make the blunder 5… e6, like in the previous game and he was keeping balance. It was developing very peacefully until move 36, too peacefully for me. Then I saw that if we exchange rooks, I can play 38… Kc5 and 39… a5 and I am stopping his queenside pawns, at the same time having majority on the kingside, clear win. Funny that Fritz thinks it is only 1.5 advantage, but after a few moves confirms it’s a win for Black.
So I played 36… Rd1 and he went for the rooks exchange, his desire to draw this game can explain it. Computer doesn’t like my 40… e5, saying that he could play 41. g4. But White is winning anyway not only after 41… h5, which I found at home, but also after 41… e4, which I would probably play there. In the game I just created a passed pawn, which deflected his king. Interesting that I had an optical illusion at one point thinking that after 48. Kc3 Ka3 he can keep my king along “a” vertical, forgetting that I can get to b4 square. He played c5 which was losing faster and resigned soon.
