Note: The game is biased slightly in favor of Dartmouth. The average probability of a Dartmouth shot being good is 62.95% compared to a probability of 61.85% for their opponent. (This makes the sample run slightly remarkable in that Cornell won by a score of 45 to 42 Hooray for the Big Red!)

(please note any difficulties or challenges in porting here)
##### Original bugs
###### Initial defense selection
If a number <6 is entered for the starting defense then the original code prompts again until a value >=6 is entered,
but then skips the opponent selection center jump.
The C# port does not reproduce this behavior. It does prompt for a correct value, but will then go to opponent selection
followed by the center jump.
###### Unvalidated defense selection
The original code does not validate the value entered for the defense beyond checking that it is >=6. A large enough
defense value will guarantee that all shots are good, and the game gets rather predictable.
This bug is preserved in the C# port.

This is Dartmouth College basketball. You will be Dartmouth
captain and playmaker. Call shots as follows: 1. Long
(30 ft.) jump shot; 2. Short (15 ft.) jump shot; 3. Lay
up; 4. Set shot.
Both teams will use the same defense. Call defense as
follows: 6. Press; 6.5 Man-to-man; 7. Zone; 7.5 None.
To change defense, just type 0 as your next shot.
