20th TT Chess Composition Microweb C 8.8.2006
Our previous 19th TT Chess Composition Microweb was dedicated to fairy helpmates. More than two dozens of problems have formed very diversified group that is still under consideration by the judge. Nevertheless I have decided not to wait any more and to announce a new tourney, already twentieth. The theme is one of those that I have been thinking of for a long time. Finally I dare to present it publicly...
Chess Composition Microweb announces formal thematical tourney for orthodox and fairy helpmates (h#) of any length showing triple avoidance (or more) in the multisolution form. Two sections are announced:
A: orthodox helpmates - judged by Chris J. Feather (Great Britain)
A: fairy helpmates - judged by Juraj Lörinc (Slovakia) - any fairy elements are allowed
Entries should be sent by email to email@example.com
before August 8th 2006. The award will be published at Chess Composition Microweb.
Please, let know your friends about our competition!
Slovensky preklad temy: turnaj je vypisany pre pomocne maty (ortodoxne alebo exo), v ktorych je v podobe aspon 3 rieseni spracovany antitrial alebo viac, v exo oddeleni su povolene akekolvek exoprvky.
Definition of triple avoidance is far from clear. Let's take as working definition the following: There are 3 moves with the same or similar positive motifs that would normally allow 3 continuations from the other side. However there are also negative effects in these 3 moves that avoid 2 out of 3 continuations.
The most usual positive motifs are unpinning, blocking and opening of line. The most usual negative motif is guarding of mating square/line.
So far we have published on CCM probably only the following thematical examples:
Special example files:
- h#2 by Chris J. Feather - triple avoidance doubled, the unpin of wS guards 2 of 3 potential mating squares so wS must choose remaining path, then bB opening line must land safely to square not guarding the chosen mating square
- h#2 by Chris J. Feather - bSb4 have to open wRa4 line, for that bBd6 have to disappear from the short diagonal, his first move determines mating square and that avoids two of three bS second moves as these would guard mating square
- h#2 by Chris J. Feather - again bSe7 moves guard always 2 of 3 possible mating squares and thus motivates choice of the first wQ move
We had only 1 orthodox and 2 fairy helpmates competing in the tourney. It was quite disappointing number. But as quality of all 3 problems was good enough for their inclusion in the award, it was prepared anyway. Thanks to mr. Chris Feather for considering the orthodox problem.
