The play and win is a joke, of course. O has a big, dead,

Well, it's a trade-off of course, but a?mercy rule threshold of 20?might
be?pushing it a bit. For 9x9, I typically use 30. If you only invoke the rule
for external nodes at least N plys away from any internal nodes, then the tree
will catch some of these problems.

Not using the mercy-rule.
I believe you can gain 10%-20% performance on 9x9 using a mercy-rule.
But in its most simple form I don't see how it can be used reliably. I
don't know if the
My mercy threshold is 27 stones, and this position is not a problem. It
gets the same win rate (10.6%) with or without mercy. The mercy rule makes
about 1.25% faster.
