Daily chess puzzle: Check Mate #377
Another puzzle from Dragoslav Andric’s 1981 book “Matni Udar”.
White to play and mate Black
Hug v Huguet, Las Palmas 1974
Solution
A nice solution, but not too hard, given the back rank mate threat: Black’s king is in a net.
(UPDATE see the comment from my reader James Clark; he correctly points out the even stronger solution than I wrote up)
1 Qd8! and e.g. 1…Rd8 2 Rd8+ Nd8 3 Nf6+ forks the King and Queen, so 3…Bf6[] 4 Re8 mate.
FEN
3rr1k1/1p2bp1p/p1n3pB/3Q4/4N1q1/2P5/PP3PPP/3RR1K1 w – – 0 1

There is a forced mate in 5 here, but it’s NOT with 1.Qd8. That actually gives away much of the advantage White has. Like you say, Black can avoid the mate by just letting White recapture the Queen instead of taking the Knight with the Bishop and he continues the struggle.
However, 1.Nf6+!! starts the forced checkmate in 5!
Thank you, James, for this correction.
