White to play and win

CH Van der Meyden v R Rubin 1962

Consider all biffs requires that 1 Nf6+! is looked at, and there really is only one line: 1…gf (though 1…Kf8 is best met not by 2 Nd7 but by 2 Qe8+ proceeding as in the main line) 2 Qe8+! Re8 3 Re8+ Qe8 4 Bd6 and black can’t prevent the pawn from promoting. (I should add that when as is my way of writing these blogs, then entering the positon into Stockfish, it prefers 4 Bf7+ first, and of course the machine is right- a pawn is a pawn).

White emerge a piece up.
