[Jacob Bendicksen]

Ignoring whether it's graciously professional for a moment, I do think it's a fascinating version of the iterated prisoner's dilemma. There's a lot of trust and potential gain involved, and once a team defects, they won't be trusted again. I agree with the previous posters who say that a tit-for-tat approach will be the best: watch the human player across the field, and when they put one in, you put one in. It minimizes losses, and increases trust.
