Not seeing it. His kingdom isn't competing for #1 land as he isn't #1 land. He'd only be in breach if, upon the age finishing, provinces from 8:9 were the only ones larger than the biggest province in 8:13.Bart agreed to not compete with ASF for the #1 land province. Bart is currently competing against ASF. Thus, he is in breach.
But that is the kicker: Nobody in the top believes that such an action constitutes a DB. If ASF can coordinate a GB on a kingdom he has a CF with in order to assist him in beating that KD later or avoiding a fight at all, I think that SHOULD count as a DB. Just as policing a KD you have a CF with is still a DB (so Bart did DB CR last age).Whether or not someone is or isn't a scumbag has no bearing on whether or not an agreement between two bodies is being violated. If Bart wants to dealbreak ASF for the stuff he pulled earlier, then say you're dealbreaking him for the stuff he pulled earlier.
As it stands, Bart is honouring the letter of his agreement with ASF and nobody but me as ever voiced the opinion that the actions Bart is currently alleged to be participating in constitute a DB. Since this particular case involves ASF, who undertook what are in my view identical actions to those of Bart not even 2 weeks prior, I see absolutely no ground you or your homoerotic friends can stand on to claim Bart is in violation.
