Did I read ScoreR in eval.c right?
White must put rooks behind advanced passed pawns after phase 6.
Black must put rooks behind advanced passed pawns.
Seems an unlikely distinction between white and black to me.
Mine has both checking phase now.
The test for Rank58 seems a tad harsh... I've seen it miss wins in
endgames because of this. But I need some more games to know if it
should maybe get a half bonus or something.
Anyone tuned HOPEN for mixed human/computer opponents - as it seems to
affect play adversely? I wacked it down to 40 for 300.
Anyone know why the two bishop bonus in eval was commented out? I hacked
it back in, but only when there are less that 5 pawns in the extended
center - seems to play like it understands the two bishops - but it does
occaisionally push pawns in and out of the extended center in a rather
perculiar fashion.... Especially when there are 4 or 5 8-)
By fixing these up a bit - I have a version currently running 4-0 up
against the original - but I think it may be all HOPEN - making it play
itself better.
Best way to randomise play/openings for self test matches?
Simon
PS: Where do I (Can I?) get the WAC test suite?
PSS: Is there a ready archive of games with the released code
base (as is - exactly) ?
PSS: What happened to bug-gnu.chess@gnu.org??
