Ouch! That is brutal! Did you really have to make it roll jokers for both sides?
I actually found it quite instructive with regard to making the most of great 
rolls, and for making aggressive early doubles.

A couple of curiosities...

Here, the game ends up as a stalemate. The program repeatedly rolls 66 for both 
sides.

Cheat mode prefers you to enter 1 chequer from the bar in these situations, 
just leaving 1 up. I'm not sure why. Perhaps it's the opportunity for X to 
crunch further, but then you'd have thought a 21 would be better.
