Frenzee does perft 7 on the initial position in 28 seconds on my 2 GHz Athlon. However that is using hash and "the Uri trick" with no make/unmake at the last ply. >I want to compare with a new concept that isn't coded yet... Just realize that this is really comparing apples to oranges. I tried using the above fully legal generator in the program as opposed to the old incremental generator, but all I saw was a big slowdown. I don't recall the exact number but I believe it was around 10-15% slower than the incremental approach. My conclusion is that at least for the frontier nodes a fully legal move generation is not worth it, at least not for a bitboarder that can easily do a much faster incremental pseudo generation. -S. >/Peter
