sprt @ 15+0.05 th 1 One idea of VoyageOne's commited patch is to give at a fail low node a countermove history bonus to the last opponent move. This move almost causes a fail high at the parent node. In this case this gives already a bonus. So try to replace the the new bonus by simply double up the standard bonus for best moves.
