Bill: I have gotten a couple of people interested in this game. 9x9 seems like a good size for serious play. Some of us were wondering about a snappier name, like Gone. (?)
Anyway, here is a 5x5 problem that I find difficult, but neat, too. Enjoy!
Impu1se: Very nice problem. There are two solutions, one of which looks like something you might do in normal go and the other like something you would never even consider. I won't post the solutions since I have yet to fully understand what's going on and only found them with computer assistance.
Bill: Ah, I missed the second solution, and I had computer assistance, too. (My intuition about this game is almost nil.)
Black has many plausible plays. Here is one that doesn't quite work.
