Critter 0.42 available

[rvida]

Hi,

Critter 0.42 is available from https://sourceforge.net/projects/critterchess/files/

My testing showed a nice improvement of at least 60 elo.

This is probably the last Pascal version of Critter. Next version will be rewritten in C and using bitboards. I think it can gain another 50 elo from NPS increase alone.

Thanks, Richard.

Observation: Performance in every single theme is improved over the previous version.

Code: Select all

Undermining                   +10
Square Vacancy                +9
Open Files and Diagonals      +8
Bishop vs Knight              +4

I expect this to be vastly stronger... perhaps by 100 elo.
