Basically, if my team picks red, no matter what they pick, they'll always get 0. They can only choose between forcing a 0 for both of us or giving the 1000. Splitting 300 300 is a loss of 400, so I'd want to avoid that.
It's a strategy copied from someone else, but I'd state that I'll go red no matter what and that I'll split. From that point on, if they want to get any money at all, they'll have to trust and take the risk of being scammed, they'll get zero either way, so they're only picking between a chance of money and being scammed and making sure that neither one get's something. Any rational person will realize that ensuring a 0 / 0 is an equivalent to taking a 0% chance at victory and that the real opponent is the game and not the other player, whereas the other option is a 50% chance at personal victory and a 100% to beat the game, so I'd bet on the other team to not be idiots and hope that my social skills can get them to trust me, to raise the odds of them not picking the spite option.
SQ, cause I'm curious if anyone has a different or better strategy.
