I was wondering if anyone has played Three-handed Chess before and what they thought about it. It seems like it can get extremely complex after just a few moves.

Better yet... does anyone know a place to play it online? If so, want to play with me?

I haven't played three-handed chess, but I have played other three person chess games. They tend to suffer from the king-maker problem. That is, one player often ends up with no chance of winning, but the ability to decide who does win.
