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).
