This was certainly PM's experience. I let it search for 30 minutes, and
it got as far as depth 12. It seemed to think there was a draw until a
big fail-low. The score had dropped to -0.59 when time ran out, but it
still hadn't found anything better. This is one of those positions which
bears closer scrutiny, in my opinion.
