Hi,

The only subtlety here, is that bayeselo is tuned for chess, and assumes 
that draws are possible, and White has a small advantage over Black. In 
order to make it work maybe a little better with Go results, you could 
do this (assuming games.pgn contains game results):

readpgn games.pgn
elo
advantage 0 ;no advantage for playing White
drawelo 0.01 ;draws are extremely unlikely
mm
exactdist
ratings

No draw at all would be "drawelo 0", but it generates some numerical 
problems in the algorithm for computing confidence intervals.

I don't expect changing these parameters would change the final ranking 
much, anyway. Maybe they would be a little more compressed, because a 
win in chess means more in terms of strength difference than a win in Go.

I would be very interested if you could lower your threshold to 197 
games, and include december results, which would include Crazy Stone in 
the list ;-)

Rémi
