I played C3 Sicilian, then realized that he’s probably gonna play …e5 because he just switched to Sicilian and has probably never seen this line before.
Once again, it got positional, nearly equal, and I should have started to play for small, dare I say tiny goals. But instead, I “went for it” (when don’t I?). He calculated better than me (he’s almost a Class B player, but he beat an Expert last week, and is doing well in both tournaments this month). I got the dumb luck reward out of this deal, and soon was playing for a win.
Then he got his pawns going on kingside, vs mine on the queenside, it was a race. I bungled in time-pressure, and finally got plumb tired as he “dropped a piece”. So, I just took the piece, decided to not even bother calculating, then looked down to notice he could push a pawn. He didn’t push it. I suppose he was trying to save this pawn-push as a threat for “later”. He spent a solid minute before not playing …f3; my quick play had probably had an effect on his decision. This game made me realize what fatigue can do, combined with time-pressure, late in games.
