Hey Gerd, yes, still bitboarding :-) I've had to catch up on all of the magic bitboard developments. Interesting stuff. It seems like that has become the popular approach now.

Yes, without bitboard bit-twiddling chess programming would be so boring ;-)
I still rely on SSE2 kogge-stone fill-stuff with vectors of four bitboards (quad-bitboards). Actually I even flip the color each make/unmake to have always white to move. I'll hope earlier or later it pays off with 128-bit SSE2 alus. Hopefully amd will overcome the current K10 (barcelona) quarrels. The announced SSE5 looks promising thought.
