Other way is to use crafty via Xboard, and put it on 'analysis >>>mode'.

That will save the analysis in a log file >(this is what I do). This is what I don't want to do, I generally want the log off. That's why "log off" is in my crafty.rc, and I typed log on when I ran it manually. >>>> But it seems like >>>>this ponder search should be sufficient. >>>> >>> >>>Most times the ponder search will not be sufficient. >> >>Sufficient for what?

The ponder search _was_ sufficient, then, because assuming that the guessed move was actually played and searching below that position is adequate to demonstrate that Crafty was incorrectly thinking that perpetual check would be the end result. Indeed, if you go far enough into the variation, it then figures out that indeed, no perpetual check is present. >>I have read it before.
