I played this Game on FICS today.
As you can see, I have nothing to lose in this game being at my 1900 floor. Okay, so that is a dry joke. I accidentally played this game, meaning to play a blitz game instead, and my first thought actually was “Wait, this guy could draw me.”
I made some poor technical moves in this game, but this is how technique improves, by playing long games.
No computer analysis, BTW.
17…b6 is clumsy. Instead 17…Nf5 holds the steady win.
After the game, I could see that my silly 30…b5 ..c4 pawn advance could have been taken down by a4.
Instead, 30…Rd7, threatening to double on the d-file, was the correct idea. So that after 31.RxR BxR, the bishop will be able to post up at e6, where he belongs.
I noticed 29…Rxd3 combo as I was making my move, but that would have given me a tougher endgame than the one I got, so it was one more chance for my opponent to go wrong.
He could have tested me with 53.Bb8, but then …f6! followed by ..Bd1 and ..Ka3 or ..Kb3 is easily winning.
Your technique will generally improve more by playing, followed by post-game analysis (without a computer).
