Thanks Patrice, the previous version of Cheese was already at the 2400 level and division 5 something I think.

Hi Patrice,

Are there any plans for a 64bit compile? Also, if you or someone else here does not mind. What are the differences between "Bitboard" and "Magic Bitboard"? I noticed a while back that Loop also uses "Magic Bitboards".

Thanks in Advance.
And Thanks for the Release 8-)

I would like to make a 64 bit compile, but now I have no 64 bit system.

This change the way to generate the moves for sliding pieces,
there is no big differences in the speed, but this helps me to optimize other parts of the engine, and the result looks faster than the previous version.
