It’s Your Move: daily chess puzzle #320

White to play and win

Kuzmin v Sveshnikov, USSR 1973

Solution

I knew this puzzle, not sure where from, maybe some article or book showing the double bishop sacrifice.

1 Nb6! : first, divert the only defender, the Nd5; 1…Nb6

2 Bh7+! Kh7

3 Qh5+! Kg8[]

4 Bg7!

And if 4…Kg7, 5 Qg4+! and the rook-lift 6 Rf3 is 1-0; or if 4…f5 (say) 5 Qg6 mates.
