interesting game

[jdart]

This was played on playchess.com com. Komodo seemed clueless that it was heading into a lost position. At this point:

[d]1k6/3b4/1b1q4/8/8/pPQp1PP1/P5KP/4R3 b - - 0 31

White has what looks like a material advantage (Rook + 3 pawns vs. 2 bishops) but in fact White is probably lost at this point. Best is probably Bb5 as played in the game, but other moves apparently win, too.

Thanks for the game. I really liked the move 15... d3
Throwing a wrench on an already messy position. Looks like that move is only for NN-type engines.
Showing 0.00 for 15...d3 according to AB engines and inferior for them compared to 15...Nf4, at least on my hardware.

edit: sorry, i loaded critter engine. SF finds this d3 move in just seconds.

I love these material imbalances that Leela seems to find all the time. Nice Game.
