David Przepiórka was one of Poland's top players in the early decades of
the twentieth century, as well as being a very talented composer whose
problems usually guaranteed a challenge for the solver.
1.Qb6 threatens immediate mate at b2. 1...e4 can be met by a check at f6, so the only defence is 1...Bb5. 2.Qg1 threatens 3.Kc2+ or 3.Qe1. 2...Ba5 can be met by 3.Kd2+ Kb2 4.Qc1+ (3...Bd1 4.Ba3) or 3.Ba3 e4 4.Kd2+, so the best defence is 2...Bd3, after which White exploits the blocking of d3 by decoying the e5 pawn to close the g7 bishop’s diagonal. 3.Qd4+ exd4 4.Ba3 and 5.Bb2.
Dafydd Johnston: The queen manoeuvre has the sole purpose of keeping the long diagonal closed by decoy of first the bishop then the pawn, and the black forces are curiously helpless against white's last remaining piece. Thank you for introducing me to another fine composer.
Jacob Hoover: This was a challenge, but the Roman decoy apparent in the 2 ... Bd3 line made it a rewarding solve.
