How to play positioms with rare material distribution
I think on 36, King takes Bishop instead of Knight takes rook forces draw by infinite check of promoted pawn to Q
Doesn't 31...dxc2 give black the win? White has to push the f-pawn in order to slay the promoted piece and in the process blows up his entire position. Violence ensues. I think a reflex aversion to doubled-pawns might have caused black to overlook the possibilities (perfectly understandable given the time constraints).
I actually think ...C2 might be more decisive, as it forces the white queen to take up a defencive position, although the pawn should promote in a few more moves regardless.
In this game I sacrificed my Queen for a piece, a rook with a pawn ahaed. In theese type of positions a single mistake can be decisive.
