Award of 20th TT Chess Composition Microweb C 8.8.2006


Although the theme - triple avoidance or more - seems to be still largely unexplored especially in the fairy field, there were only 2 fairies and one orthodox helpmate competing. Fortunately, all of them were good enough to be included in the award.

Familiar triple-avoidance play by the black knight, but here occurring (less usually) on the second move, after differentiation by unpins which are also unguards, one anticipatory and two direct. A pleasing piece of logic without too many plugging black pawns, but the white ones, necessary to control the queen's movements, are certainly regrettable. I can declare without fear of contradiction that this is the best problem in the tourney, but although it is attractive, it is not quite good enough for a prize. (Chris Feather)

Quadruple avoidance in the most unexpected problem of the tourney. Black knight has to free d1, Circe square of white queen. He has to choose his arrival square wisely to avoid either guarding of mating square, guarding of mating line, closing the mating line or, in the emphasized most Anticirce cases, guarding of Circe square of white mating unit. I liked the fact that quadruple avoidance is not shown in 4 blocking moves. But the unused Gg5 in the (first) "rook" solution prevented me from awarding the prize to this problem.

More conventional four-fold blocking already in the first move by 4 units that also unblock - form and antiform of motif in the same move. In the rest of solutions both sides strive to allow mate by nonstop equihopper over the same white knight. The geometry of the board is extremely well employed, even if the (second) nonstop equihopper solution is different from others as it does not use unpin of white knight, it is still similar enough not to disturb unity too much. Of course, economy of white force is flawless here. (Juraj Lörinc)
