Gerd has worked hard over a long period of time, so any success would indeed be well deserved.
Thanks for your kind words, Graham. I have to admit that the current HansDamf, which played in Wortel and Leiden is still more 32-bit IsiChess MMX than the initial devoted 64-bit SSE2 HansDamf, which is a color-flipper (flips the board after each move, so the computer is always white to move) and will blow everything away
(With a decent eval and parallel algorithm still in progress).
Cheers,
Gerd
Wish you all the best Gerd with your work over the beast

Interesting idea!
Does it also only evaluate white pieces (e.g. by maintaining both color orientations)?
I may steal your idea...

Actually it seems an old idea, already used by Peter Jennings with MicroChess.
One has only to generate white moves. Evaluation however considers both sides so far, also based on attack sets for white and black pieces. It safes some indexing by side to move and I guess there are some EGTB implications as well. Color-Flipping the board during make/unmake is quite cheap with quad-bitboards.
