Computer simulation problem

[microbet]

You have 5000 players and they come in two flavors. Whenever a FlavorA player plays a FlavorB player the FlavorA player is 60% likely to win a small amount of chips and 40% likely to lose a small amount of chips. When a FlavorA player plays a FlavorA player they are 50/50 to win/lose a small amount of chips. When a FlavorB player plays another FlavorB player they are 50/50 to win/lose a large amount of chips.

Construct a tournament where there are only HU confrontations, obviously, and play with the ratio of FlavorAs and FlavorBs and also what a small number and what a large number of chips means and see what happens, perhaps over a large number of tournaments.

Program the simulation and give us the results or just comment on what you think will happen.
