It’s Your Move: daily chess puzzle # 77

Black to play and win

Portisch v Smyslov, Amsterdam 1964

Solution

A nice, but fairly standard motif: sac to open the h file, a few checks, and then advance the f pawn to create threats on the black squares.

1…Ng4! 2 hg[] Qh4+ 3 Kg1[] Qg3+! 4 Kh1

4…f2! threatens Qg1mate, so the Bishop must move, and if 5 Bg2 Qh4 mate; or 5 Be2 Qh3 mate.
