furbster: can't really comment on a running game. (I nearly did...) Looking at the ratings though, and knowing tenuki, I'd say he should know what he is doing, and he is not known for dragging games out.
Aganju: I remember an strong arbitrator, when told by a player the game was a draw, that he could beat either player with either colour from that position. Probably true as well.
