Hi Leonid,

Do you mean to say that if a position has more than 100 possible legal moves,
Rebel won't accept it or maybe even crash? I own Rebels 7, 8 & 9, but I can't
recall ever having read that. Have you tried it with a 'heavy' position?

I also don't know about Genius (I have 1,2,3&5) unfortunately, as that's not
something that is usually in a user manual.

My program doesn't have a limit per position ... I generate pseudo legal moves,
and the moves are all added to a big 1-dimensional array; moves of each new ply
being added at the end of the moves of the previous ply. So I never run out of
space, well, erm ... unless I search too many plies of course ... :)

Salut,
Paul
