I would put $0 in the pot and if my opponent put in more than me, I would pay him until we were even. This beats the game because it sets a cooperative standard while being fair immediately and also protects me. However, if my opponent put in more and could punish me before I could even it out, I imagine I would find it hard to "turn the other cheek." I also don't think that putting in the full amount would create the culture I would want to exist because such an action would be indiatinguishable from naïveté, and other than asking for my money back and getting it I would have no power to do good once the game ended
