I've been faced with this dilemma before and have always just not bothered to pursue the alliance but I'm just curious what you think.
It is obvious that any unannounced alliance is strictly forbidden. However, what is the opinion of initiating an alliance in confidence and then announcing it to the board when it is official?
My point is, the mere suggestion of an alliance can cause an non-included person to retaliate even if the alliance is never agreed upon. It would be nice to test the waters privately before continuing in the board chat.
It really doesn't need to be an alliance as much as a one turn agreement or some such.
Thoughts?
