I would rather have 4th place. I see no merit in taking revenge. Also, especially with this game, I would blame myself for not seeing the betrayal, and not the opponent who betrayed me. At least, assuming it was a rational betrayal, they must’ve gotten to a better position by betraying me than by not betraying me; moreover this has to be significantly better, since my opponent does not know if I would retaliate.
For example, in round 17 I was betrayed by le_4TC, who had agreed to capture Haze. But It was really my fault for being naive enough to believe le_4TC would grant me such a nice position with barely getting anything in return.
That even extends to daily life: only harm comes from revenge. Of course it’s bad strategy to announce that you don’t retaliate or never take revenge, since that makes you exploitable. Therefore this might all be a very elaborate ploy to trick people into mistakes in my future games. Or at least, that’s what I want you to believe ( or is it? )
