Daily chess puzzle: Check Mate #190

Another puzzle from Dragoslav Andric’s 1981 book “Matni Udar”.

Black to play and win

Castaldi v Romano, S Benedetto dal Tronto, 1953

(Megabase has the game as being played in 1990: either might be correct: it could well be a veterans’ game, since Castaldi was active in the 1950s.

Solution

1..Nd3+! has to be played, and the N has to be captured, since it is a fork on the Q. So 2 cd Qd3+ and mates.

The game, in Megabase, seems wild: swinging both ways.
