I just checked to be sure; Steenvreter correctly passes in both examples. I'm speculating, but I think your problem is that you only adjust for the difference between Japanese and Chinese counting in the playouts. However, once consecutive passing gets into the tree you have to correct earlier. The way I think of it Japanese rules have two phases: (1) the game phase and (2) the confirmation phase. In the game phase passing first can gain a point. In the confirmation phase it can not. The confirmation phase normally starts after 2 consecutive passes. If the confirmation phase has not started yet in the tree then the entire playout can be considered a confirmation phase.
