Kurze Beweispartien

von Mark Kirtley

Teil 2, Probleemblad 2000, Einleitung

Following the first article (PB 1999-3), here is another collection of proof games with solutions in no more than 7.0 moves. They are all shortest proof games this time.

№1 has a deceptively tranquil look in that no surviving piece is away from home.

In the next three examples no pawn is away either. This suggests a history of switchbacks, and one of the four compositions has a remarkable abundance of them, while another hasn't any at all.

Peter's №5 is perhaps the only proof game ever composed with three equal-length solutions without twinning. There were two shorty composing challenges given in the first article. One of them asked for an AUW, although I had real doubts that it was possible.

But in №7 Gianni presents it to us. The other challenge was for two tempo maneucers on the same side in one line of play.

№8 is an answer from the combined efforts of Joost, Gianni and Michel, which incredibly has a third tempo on the other side.

All the examples following №8 also have tempo play.

Gerd's №9 has now-you-see-them-now-you-don't cross-captures.

The quiet attractiveness of the five-move tempo trek in Pascal's №10 is combined with a second surprise.

№11 has a theme and an anti-theme.

Michel's №12 gives the seeker of beauty a lot to smile about. One of its themes has a name, but I think the other one is new. Many thanks to those composers who contributed their suggestions and originals!
