I put a bunch of positions in a file, and run the "evtest" command. I then look at the positions, one by one, noting Crafty's static evaluation. If I disagree, I flag it to look at. If not, I keep going. It is good to catch oddball cases that trigger unexpectedly large scores for the wrong reasons.
