This problem originally had a bB on h7 to thwart the try 1.e3? but was later removed and now has two solutions. We have wonderful play in both solutions including Schiffman defenses, pin mates, battery play, and a true Salazar theme (reversal of key move and variation). 1.Sc1! (>2.e4) 1...Kd5 2.Bc3 1...Qxd4 2.e3 1.e3! (>2.Sf4) 1...Kd5 2.Sxb4 1...Qxd4 2.Sc1 |

This is probably my favorite double solution problem. I love line doubling and this is a wonderful example with two flight giving keys and perfectly match play in each solution. 1.Qxc5 (-) 1...Kxe6 2.Qc6 1...c3 2.Qf2 1.Qxc4 (-) 1...Kxe5 2.Qd4 1...cxb4 2.Qf1 |

In this problem Black does not have any moves so White must give the bK some room to move. A different piece plays to the f7 square to release the stalemate. 1.Sf7! (>2.Sxh6/Sxe5) 1...Kxh5 2.Sxe5 1...Kf5 2.Sxh6 1.Kf7 (-) 1...Kxh5 2.Qh3 1...Kf5 2.g4 1.Bf7 (-) 1...Kf5 2.Bxe6 1.Rf7 (-) 1...Kxh6 2.Rf4 |

Problems with multiple solutions make for a nice platform for cyclic play and here we have a beauty. In this problem the wRs and wQ take turns pinning for each other and mating. Set wQ=A, wRd3=B, and wRb5=C 1.Bg3! (-) 1...Kd5 2.Qf7 (A mates, B pins) 1...Sd~ 2.Rbb3 1...Sxb5 2.Qxe4 1...Se~ 2.Rc3 1.Bf6! (-) 1...Kd5 2.Rxd4 (B mates, C pins) 1.Be7 (-) 1...Kd5 2.Rxc5 (C mates, A pins) |

Here is something exotic from the British grandmaster. Notice that the bK has many flights, five to be exact: e4,e5,e6,c4,c6. Here the three solutions all have checking keys but there is beautiful mate transference on the e-file flights and changed mates on the c-file flights. A wonderful problem which goes beyond the usual problem conventions. 1.Sf4+! 1...Ke5 2.Re1 1...Ke4 2.Re8 1...Kc6 2.Rf6 1...Kc4 2.cxd3 1.Sf6+ 1...Ke5 2.Re8 1...Ke6 2.Re1 1...Kc6 2.Bb7 1...Kc4 2.Rf4 1.c4+ 1...Ke4/Ke5 2.Re1 1...Ke6 2.Re8 1...Kc6 2.axb5 1...Kc4 2.Qxd4 |

Finally here is one of my own. You may recognize it as a modification of one of my old problems. It is nothing special but it does have some interesting features. First, it is a complete block - every move by Black has a set reply. For complete blocks, there are 3 three types of non-threat caring solutions: a pure waiting solution, a solution with added mates, and a mutate. Each of the solutions accomplishes one of these. Set: 1...Qd4+/Qd3/Qd2 2.RxQ 1...Qxd1 1.Rxd1 1...f5 2.Bxe5 1.Bh2 (-) pure waiting move 1.Bf4 (-) added mate after 1...exf4 1.Rh1 (-) change after 1...f5 2.Rh6 |
