Yes, that's a good measurement for the volatility. Of course it should be 2-ply variance, since the that's what can happen until it's your turn again. I believe the doubling algorithm in Jellyfish worked with at volatility based on the 1-ply variance, and that algorithm wasn't bad. Implementing such feature in GNU Backgammon should not be difficult, however... hmmmm... where would we integrate this in the GUI? and how do we set the evalcontext etc. Small problems... can be solved.... -Øystein
