White to move
After 23...Rxb2 Draw agreed |
I began with a move that looked good to me while playing through the game on Fabror's blog, and that was discussed there.
24.h6 Rb8
I expected 24...g6
25.hxg7 Kxg7 26.Bd3
Rybka expected 26.Rh4. Running Hiarcs 12 as I annotate this exercise, I find that it prefers my move.
Black to move
26...Rg8 27.g4 Kf8 28.Bf5
Now that the pony on a2 is undefended, I'm looking around for a lasso.
28...Bxf5 29.gxf5 Rg2+ 30.Kd3 Rg3+
White to move
31.Kc4
Rybka expected 31.Kd4. Hiracs concurs that this move is best until it thinks longer, then it chooses my move. I used a mere three seconds to play my move. Several moves later, there was a moment where I perceived a checkmate threat that I needed to avoid.
31...h6 32.Rxh6 Kg8
White to move
33.Ne8!
I love it when the computer gives an evaluation of the position that then takes a jump up several pawns after I make an unexpected move. Rybka had +4.49 before 33.Ne8, but +9.66 afterwards. Hiarcs found this move after several minutes, and its evaluation jumped from ~+5.00 to ~+7.50 and continued to climb while I typed this comment. I spent twenty seconds finding the move. Of course, I do most of my thinking while the engine thinks, and 32...Kg8 was easy to predict.
33... Kf8 34.Nf6
I spent 2:12 on 34.Nf6 because the second best move was tempting. Here I saw the nasty disappointment that could have occurred. 34.Rh8+ Ke7 35.f6+ Ke6 36.Ng8+ Kxe4 37.Ra8?? Rc3#.
34...Rc3+ 35.Kd4 c5+ 36.Kd5 1–0
Black to move
Black gave up |
Rybka 4 resigned. I foresee hiding my king behind Black's c-pawn where he helps stitch together a mating net for the enemy king. It's always nice to humble the silicon beast, even from a set-position that is theoretically winning.
Very interesting!
ReplyDeleteGlad you like it Patrik. Interesting exercises come from interesting positions, and I had some good raw material to work with in this case.
