Again, this is not entirely new. The suggestion to enhance the race DB is based on the assumption that the bot misplays those positions. I would like to see the evidence for that. I think I will start an effort to measure the race net error just to make sure (similar to the crashed net). Also, I find it hard to belive the bearoff database is insuffcient. Can you pose this Q to Neil? i.e. can he provide a set of positions GNU mishandles?

I think there's a bit of a misunderstanding here. As far as I recall this discussion on GOL, Neil Kazaross was thinking of SNOWIE 3.2 here (Neil has only just started to use GNUBG seriously). SW seems to play races and bear-ins poorly, and perhaps even bear-offs (cube actions?).

However, my experience with GNUBG and its RACE net and databases is that together these are very accurate already (and fast), even at 0-ply!

I'm pretty sure there's very little room for improvement in this area with GNUBG. Seems to me it'd be much more efficient to try and improve GNUBG in other areas (like the training of the CRASHED net done right now).
