I tried to run Chispa on my Athlon and it lost every game (out of 40), even against engines of Elo 1500.
Something is broken it seems.

If you add the letters PR9 to chispa it seems to play better and it even can beat movei(inspite of losing the match 3-1)

Seems that the problem is only in UCI mode because don't uses the configuration file chispa.ini. The problem is caused by the default piece values. I fixed the problem and I released Chispa 4.0.1. Thanks for the bug report.
