Daily chess puzzle: Check Mate #15
Another puzzle from Dragoslav Andric’s 1981 book “Matni Udar”.
Black to play and win

Nepoznati v Derrickson, Philadelphia 1862
Solution
Straightforward today: check, check and mate: 1…Ne3+ 2 Kd1[] Ne3+ 3 Kc1[] Ne2 mate.

You need to correct the stipulation to “Black to play and win”. I endured almost a minute of intense puzzlement while I tried to find a checkmate for White.
