It’s Your Move: daily chess puzzle # 21

June 15, 2015

White to play and win

 

Schuster v Schurr, Stuggart 1962

 

Solution

 

A fairly standard problem, one of overload, or the black queen being tied to the defence of the Rb8. So 1 Qd4! (not 1 Qf4? Qa1+) and after 1…Qd4 the zwischenschach 2 Rb8+ wins. Note that as well as Purdy's concept of tie being a motif, the combination also works because the black queen is a LPDO. If the Qe5 had been defended, e.g. by a Pf6, the combination wouldn't have worked.
