Daily Chess Puzzle

I found today’s problem whilst searching, without success for the previous game won by Bruce Hayden on Megabase and chessgames.com. Looking at his games on the latter, I found this sparkling attack. The full game is in the FEN section below.

Since the start of 2018, I have decided to adopt the style of only saying which side is to play: and not giving an idea if the move wins or otherwise, unless on occasion I think signposting would be helpful. Instead, the problems are posed with the instruction to decide what you would play, as in a game.

White to play: Black has just played Qe7-c7, keeping an eye on the Pe5. Evaluate

Hayden v Winser, Hastings 1947/8

Solution

1 Nf5!! is the sparking solution.

1…gf is trite: 2 Bf5  and 3 Bh7+ next. So 1…Bf8

2 Be5!! and if 2…Bh6 3 Nh6+ and 4 Qc7 and White emerges a lot of material up. Black played 2…Qd7 met with by 3 Bf6 Bh6 4 Nh6+ Kf8[] 5 Nh7 mate.
