David,
Confession: I have not tested 19x19. As you have noted, and others before
you over the years, a 19x19 board does not fit in one but three 128-bit
registers and there would be a rather big penalty as a result, perhaps
(likely?) wiping out all of the benefits of bitmaps. Antoine voiced his

If an engine (or an engine's playout policy) needs to check the legality of
every move before making a selection, this could still be a benefit.

Lukasz,
I tested Libego version 0.125 on my labtop, compiled using Visual Studio
2008 under Windows XP with slight modifications:
#ifdef NDEBUG section commented out in "testing.h"
#include added to "fast_random.cpp"
>From the command-line with "engine -b" I observed 67-71 kpps on the same
labto
Oops,
Speed drops more that the (per move) estimate below due to the increase in
length of the game as well, of course.

Maven was fast enough, but it was clearly the slowest
of all major Scrabble programs. Some programs were 5x
faster than Maven. Maven was slow because it was a
lot more than a move generator: it played the full
game with competent positional scoring. Scoring
requires much more time than move ge

Getting similar speed to Libego is very impressive. It’s important to start
with a fast basic engine, since it will only get much slower as you add more
knowledge. Currently I only get about 19k playouts per second on a 2 core
Core2Duo 2.3 GHz, on 9 line empty board. I started at about 55k pl
