I don't do anything special. I hash the presence of a simple ko in the 
current position, so that the positions with and without the simple ko 
are considered different. I don't do anything special for superko. I 
know there is the GHI problem, but in practice, I have never seen a bad 
move played by my program that could be explained by that.
