His infraction is not as clear as you make it out to be. You ascribe motive, seeing mines were allowed and using them despite agreeing not too, where simple neglect, forgetting that no mines were agreed to, could sufficently explain it.

On the other hand you saw that the game settings were misconfigured and made a concious decsision not to bring it up. Your motive was completely innocent, not wanting to give up strategy information, but you cannot claim that you simply forgot the setting as he can.

Your race analogy is flawed. It's not reasonable to think someone would simply forget that the race is a foot race. The person could split hairs and say "We never specifically agreed to NOT ride bikes.", but it wouldn't pass a common sense "BS" test.

Clearly there is no perfect solution. If I were the game owner, I would suggest a restart. Obviously though that will damage you in that the element of suprise of your fighters will be lost. You can come up with a new strategy for your next game though. He cannot get his research points back in this game if you were to continue though.
