crafty hash bug(2) ?

Post by Cardoso »

Hi,
It seems crafty now adjusts mate scores on bounds both on HashProbe() and HashStore().
Shouldn't it only adjust on EXACT?
Or am I just seeing things?

Best regards,
Alvaro

You have to adjust the bound as well, since a mate bound was a mate score at some point in time.
