Computer simulation problem

[Slim Pickens]

So here's what I did in one hour:

2 Type A's and 8 Type B's

A's vs. A's: The amount wagered is 1/4 of the smaller stack, unless the difference between the two is greater than a factor of ten, in which case the wager is the entire amount of the smallest stack.

A's vs. B's: Same as above, except A's win 60% of the time.

B's vs. B's: The wager is the smaller of the two stacks.

They start with 20 chips each and go until someone has all 200.
Player Type A wins 256/1000
Player Type B wins 744/1000
