xGo implementation

xGo is more like Go than like Hex, but I am arguing that the best way to settle a Go game is by playing Hex at the end, instead of counting stones and arguing about komi. This could be of interest to Hex players? You can try xGo (playing locally) here.

Basically, you play Go (with the pie rule) until both players pass, and then switch to Hex. There is a bit more information on wikipedia.
