These words of Akiba Rubinstein should have been my motto last week, on Monday. I played with the guy that having ~1400 rating managed to get 3.5/4 and beat 3 guys in the 1500+ – 1700+ range. So he looked like a “dark horse” and it got me nervous.

I got White and we played Sicilian, Moscow variation. After he played 15… f5, he started an attack on the kingside. I immediately started a counter-play on the queenside. The first crucial moment came when he played 23… Qh5, it was a mistake. I saw Qc8 of course, but didn’t quite like his bishop jumping to h4 with a tempo and also probably didn’t want to leave my kingside without my queen’s protection. Computer says that after Bh4 I could take on b7 and then advance my “b” pawn to b5, then b6, with rooks protecting at the same time my king.

Then I had an advantage after playing 28. Rc7 and again didn’t use his 28… Rf7 and moved back to c2. After 29. Rxf7+   Kxf7 30. Qc2 my queen was terrorizing his queenside. So I missed it and then mistakenly took on g3. From that point he intercepted the initiative and my position started to deteriorate. It didn’t help that I had less than 10 minutes left. The game losing move was 43. Rc1.

I was very disappointed, even more when I came home and saw that I could win.
