Plugging in a Winning Strategy: Exercise 6.18, p. 160

• Name your winning strategy procedure intelligent-strategy-2-pile and test it on some game states.

• When you're satisfied it works correctly, plug it into your program by changing nim so that intelligent-strategy-2-pile replaces simple-strategy.

• Now, if the computer wins the coin flip and plays first, it should force a win. If it does not go first but the human does not know the winning strategy, it should also force a win.
