Has anyone else come across this?
Does RHP have something as good hidden away? The power of it is the way that the next move options are displayed which makes it very easy to navigate.
If RHP doesn't have anything like this, then we could make one, using rhp's game database perhaps?
One problem with the one above site is that if a position can be reached by more than one sequence of moves, the win/loss percentages suddenly jump when the common position is reached, it would be interesting to try to correct that in our one.
