The attached example shows that a *good rule* might break the balance of playouts and produce a worse evaluation.
Suppose in the playout we add a new rule to forbid B's D1 self-atari. This rule makes sense since D1 is a completely meaningless suicide in terms of Go knowledge. But, in fact, this rule might break the balance of the playouts in the sense that B now has a higher probability to live by seki (if W doesn't capture at D1). And B's *live by seki* is a *wrong* result here. The correct result of the playouts should be W kills B with 100% probability. So, along with the rule prohibiting B's self-atari at D1, there should be a new rule to make W capture at D1. Then, the playouts can be balanced toward the correct evaluation. Rules for semeai are usually much more complicated and might break the balance in this way. Aja
