When you say similiar results - do you mean the exact same condition as in the CP condition or just other incorrectly reported results. I know there are some bugs with arena that do not like the "I claim a draw" annoucements that are now in Crafty and will misrport drawn games as losses for Crafty. I set up a special parameter in Crafty SE to address that issue and the command is "arena on" which fixes that nuance and the search time per move issue as well. It's too hard for me to keep with every GUI and the little differences bewteen them so I recommend using either Arena (be sure to have "arena on" in the crafty.rc file) or Winboard. I have totally given up on Chessbase with their GUI sending a "new" command every single move. That is simply too disruptive to Crafty SE using the wb2uci.exe adapter. Michael
