I own Rebels 7, 8 & 9, but I can't >recall ever having read that. Have you tried it with a 'heavy' position? Not at all! It will not crash. Only he says openly that its number of moves is limited to 100. I remember that I tried on it few positions (don't know how many moves they had but they were heavy) and he responded in perfect way. Only since it indicate 100 moves limits I don't try on Rebel positions that goes beyond 100. >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 ...

So I never run out of >space, well, erm ... unless I search too many plies of course ... :) My program have its limit for now. It is 200. Will change this in the next version when I will go to the other system after DOS. Will put 300. Actual limit of 200 is for the number of legal moves that move generator creat. All moves, in my program find (few exceptions exist) before each ply, so your expression is completely unclear for me: "unless I search too many plies of course...". Or "moves of each ply being added to the end of the moves of the previous ply". Probably you do something completely different from me. I even don't know how to ask you in order of finding where is the difference. Salut, Leonid. >Salut, >Paul
