I can't say for the large troops advantage green (captain bonehad) might have had earlier as I wasn't there and I don't have access to snaps.
But you are saying he had quite a large stack on Bogota and did nothing with it.
You complained on round 27, as the log said, he broke green bonus 3 times before that.
Also, since he was the smaller player, it seems smart play to stack and let both of you fight, hence the stack on Bogota he might have had.
If he was trying to hand the game to green/captain bonehad,he wouldn't have been stacking Bogota, he should have been stacking asia, or Sao Paulo.
Also he shouldn't have break 2 times Captain Bonhead bonus earlier in the game.
Actually you are round 30, and ok seems right now captain bonhead has an advantage, but your total number of troops aren't that far off, and if both red and you work together you should be able to keep Captain Bonhead in check. To reach round 30, to me, it means red was successful in preventing any of you to take the lead.
You dont find it strange they play a ton of 3 player games together without sharing that info?
Do you mean they should have disclosed beginning of the game that they often play together ? If that's what you mean, no I don't think they should disclose it.
Also they played 40 games together, over 1365 for jwo and 1701 for Captain Bonehad.
I'd assume they noticed each other, especially since those are 3 players games. But seems they like the same settings mainly. It's not that many games played together either.
I think jwo might have done what you think is a poor move, and maybe a move that could give the game to Captain Bonehead, thus it made you a bit angry, and then suspicious.
But I think it's only one bad move over 30 turns. That's all.
