1....Ng5+ 2.Kh4 Qe4+! 3.Kxg5 Qg4+ 4.Qh6 Qh5#, and all white's move are forced here.
this one is from a tournament game i played in chess.com, i also found a forced mate here for white, my oppoment immediatly resigned.

started with a non-check move 1.Ng5!!, threats Rxh7# if fxg5 2.Qd4+ and follow by mate; so after the Ng5, no pieces can protect h7 square, then and now black can only delay mate but cannot stop the mate.
