(Problem 212) Yuri Antonov, Hlas Ludu, 1981 Mate in 2 moves. #2 (8+6) | |

Tries : {1.Rd6? cxd6!}, {1.Rxc7? / Sf7+? Ke6!}, {1.Re7+? Sxe7!}, {1.Sg4+? fxg4!}, {1.Rxe4+? fxe4!}, {1.Qa1+? Sc3!}, {1.Qxd5+? cxd5!}, {1.Qd4+? Kxd4!}.

Let us observe a little closer the play after the next try, in order to compare with the post-key play :

The problem contains the theme [Lacny 2x3] (two phases and three variations with cyclic permutation of mates).

Theme Lacny pxv. It is developed over various phases (the number of phases is p). In one phase there are some (a b c ... z) defences (the number of variations is v) which are answered with the mates (A B C ... Z). In another phase the same (a b c ... z) defences are answered with a cyclic permutation of the mates (B C ... Z A). The theme is named after the composer Ludovit Lacny, who has published in 1949 the first problem with relevant content. |
