Detailed Description

Efficient implementation of a SgMiaiStrategy.

The miai strategy must be achievable (not broken). Uses two boards, one for each color. Board entries either point to the miai point, or are set to SG_NULLPOINT if the point is not part of a miai. Can only be used going forward through a game - does not support undo.
