Subject: draw by repetition and hash tables

Author: Inmann Werner

Hello all!

can anybody help???

I have some problem to implement draw by repetition in my program.
If a position is reached the third time, its a draw by repetition. Ok.
But the position has an evaluation. But because of the draw I return zero
(draw). Now all positions before in alpha beta get a Score of zero. OK.
But this values also may come into the hashtables, and thats really bad and
not correct!
Does anybody have the same problem, and maybe solved it?
