Daily chess puzzle: Check Mate #200

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

Black to play and mate White

Solution

The first few moves are obvious, and Black also has the crutch of a perpetual check to rely on, if he wants to.

So, 1…Qe3 2fe Ng3+ 3 Kh2[] Nf1++ 4 Kh1[]

That’s as far as Black needs to visualise, since he can now Ng3+ Nf1+ Ng3+ to his heart’s content; but it isn’t too hard to see that moving the N to e4 also threatens Nf2 mate, so forcing g2-g3:

4…Ng3+ 5 Kh2[] Ne4+ 6 g3

and now Rf2+ and Ng3 mate.
