thx for your input, it's already solved though
In any case I was A and I was going by B's follow up to adding the clause
B: but let's discuss it further or because the game can be in a position that is much more advantageous to one in the end so making taking the last one delicate
This to me signaled that the whole deal is being overhauled and we expect to stay till we are the very last in the game, then after B denied ever agreeing to the clause in the first place just cemented my position that he understood it the same way I did and is now just wiggling out of it
Someone pointed out that in my answer
A: sure, but then if one side refuses to finish off the opponent the other side can just end the truce normally with 2 turn notice
the part "but then ... normally" could be interpreted as though we can still do the normal 2 turn notice at any time whilst I only meant it as another amendment
also yes it's an FFA and yes technically any deals are not enforceable, but since we both maintain that we are not breaking the deal and have no intention to do so, then arguing about it is meaningful (unless one of us is dishonest but in that case why would they bother to defend it?)
