Subject: NULL MOVE

Author: Sylvain Lacombe

I just finished implementing the null move. At first, i thought it wasn't saving
much time. Then, i reallize that it does save alot, but only at deeper plys. On
the first few plys, i think, it evens slow me down. Is that normal? Am i doing
something wrong?

I don't use the null move at the first ply, only at the second. It save about
40% reaching deep 6. But it takes about 10% more for reaching deep 3 and 4.

Hope, you can help.
