Hi,
I downloaded crafty 19.1 a few days ago, compiled two versions of it, and tried
to matchplay the engines against eachother in winboard.
My problem is that the openings are always the same.
If I input the moves manually from the console, both engines will vary the
openings.
I've tried different books for the engines, I even created my own book, but the
result is the same. The opening will be different depending on the book used,
but that opening is repeated over and over.
My winboard mycrafty_vs_crafty.bat file looks like:
winboard -fd craftyMy -fcp mc191.exe -sd craftyOrg -scp wcrafty191.exe -tc 10
-inc 2 -matchGames 20
The crafty.rc files which look alike for both engines currently looks like:
learn off
ponder off
book on
book width 5
bookw CAP 0
bookw freq 0.1
show book
resign 5
hash 64M
hashp 2M
I've tried a multitude of winboard command lines and various .rc files, but the
result is the same. "book random 1" has no effect.
Always the same opening :-(
My logs show that the P% (playing percentage?) in the opening is always 0...
Could that be the problem?
