Here is a position from the DF7/Kramnik match posted earlier. I noticed I did not get the same output from CM9K as John did so I ran some test. Here are the results of running the same position on an AMD 1.4G machine using different hash table settings (4M-64M). I am wondering what causes this kind of behavior.
