Test your chess: Reitstein problem 57

Black to play and win

A Bock v CAL Bull 1899

Solution

CJS Purdy recommends that his readers look for jump checks and one of these is 1…Q(jump)f3+: if the queen can get to f3, the check may well be ruinous. So 1…Rg4+! and 2 hg (2 Kh2 Nf3mate) Qf3+ and 3 …Qe2 wins.

In fact, black has even stronger: 2…h3+! and if 3 Kh3 Qf3+ 4 Ng3 Rh8 mate.
