24th TT Chess Composition Microweb C 10.10.2008

The choice of theme for this TT was not very difficult. It came out quite naturally...

If I today asked someone not knowing much about chess composition "What is twinning in chess problems?", chances are that he would turn for answer to Wikipedia. And it is easily possible that he would stumble upon this entry. It shows as an example of twinning memorable Forsberg's twin helpmate. By the way, I have used it in one of chess composition blog entries.

Well, there was recently also a theme tourney of Problem-Echo dedicated to h#2 where in twin equihopper(s) replaced grasshopper(s). The tourney was very fruitful. Therefore I have asked the second-prize-winner from Problem-Echo TT to judge our tourney.

Announcement

Chess Composition Microweb announces formal thematical tourney for any type of chess problems (both orthodox and fairies are accepted). The problem should use twinning by replacing a piece by any other piece on the same square and there should be at least three positions (twins may be made by replacing pieces on the same square or different squares). See examples for more clarification (please return for more examples later).

Judge: Michael Barth (Germany)

Any stipulations and any fairy elements are allowed. The tourney might be divided to multiple sections if enough problems are received depending on the opinion of the judge (e.g. orthodox - fairy, direct - help, or whatever any division judge deems suitable).
