1. Bf7!
…threatening both Qg7+ as well Qg8+ mate. There is no defense!
1. Bf7!, threatening 2. Qg8# and 2. Qg7#, looks like a winner.
Bf7 threatening mate at g7 and g8.
1. Bf7 threating mate in two places looks interesting.
Harder than the Gulko tactic from yesterday in some ways. Took me several minutes and a couple of sidelines to spot the mating net. White can win, I think, with the simple Be8- black takes at e6 and white takes at h5, and white has some initiative and four pawns for the piece, but the move that caught me first was Bf5:
1. Bf5 Bf8
Much like 1.Be8, white’s pawns are too numerous for black to bailout with Re6, so g7 must be guarded, but it can’t be by any piece from a safe square:
2. Nf8 Bf7
3. e6 and white will win easily due to the multiple threats.
However, 1.Bf5 has a cousin- 1.Bf7, and this move mates because it opens up twin mating threats on move two- 2.Qg7 and 2.Qg8, and black can’t parry both:
1. Bf7! and there are only delays like sacrificing material at g5, g6 and c5. White will mate in no more than four moves total.

Bf7 followed by mate on g7 or g8
1.Bf7 with threats of # on g7 and g8
1. Bf7 looks good to me setting up mates on g7 and g8. Black can’t cover both.
1. Bf7 and there are two mating threats and Black has no time to avoid both
Hi Susan Polgar,
Well,already others had given the best possible move – nothing to add further.
