Award of 6th TT Chess Composition Microweb C 1.4.2001 - #2, #3 section

Judged by Thomas Maeder.

There were 8 problems to judge in directmate section. I have discarded nos. 07 and 08 because their construction has a lot of superfluous force in each phase. 05 has three unprovided flights in the set play.

I considered including 01, but I prefer to give the author a chance to correct a slight lack of thematical balance: after 1.Gc5!, the relation between 1....VAc2 and 1...VAc4 isn't a correction (as indicated in the solution), but a reciprocal dual avoidance: both Vao moves to the c file would allow both thematical pieces to go to c7, were it not for the pin effect of 1....Vac2 and the interception effect of 1....Vac4.

04 is well publishable in a magazine, but the contents isn't sufficient for an award.

There remain thus three problems:

Prize: 02 by Reto Aschwanden (Switzerland)
By far the most ambitious idea of the tourney. I am not absolutely convinced that the board has to be as large as this for this matrix, but how much cost is another row and column once you have exceeded 8x8? Kamikaze and the Chinese pieces are well integrated to produce this flawless cyclic play.

1st Comm: 06 by Georgij Jevsejev (Russia)
The small brother of 02. It's funny to discover the differences in the roles played by the hoppers and lions. Unfortunately, there is a lot of symmetry, the Leo isn't well integrated, and the Rookhoppers only play actively in one of the phases each.

2nd Comm: 03 by Georgij Jevsejev (Russia)
I have a hard time resisting to gems like this one. I tried to get rid of the VAa2, but haven't succeeded. The position of the black Pao makes one think about adding g8 as another flight; who manages to do this while preserving the excellent construction?
