- Abacus.

- Actually, brute force programming. It took about 10 minutes of CPU time
- for each pair of hands, which is why I only did a few cases. Since each
- player can have 169 different starting hands, there are about 29000 cases
- that can come up in a two player game. That is a lot of cases to handle
- at 10 min. a pop. A complete analysis will require a much more
- sophisticated program (yes, I'm working on it, but I don't expect results
- for many months).
