If he accepted your flag and THEN truced 1/2 with someone else, then no, you did nothing wrong.

yes it was like that. thank you

Did you make a pre-game alliance? Did you play more than one player on the board? Neither of these? Then use whatever advantage you can to increase your position. Whine complain back stab break your flag who cares. Its all not against any rules other than the lame unwritten verbal flag silly rules that are grey anyway. You did nothing wrong

What pink said. As long as its after you flagged, you can't be expected to honour your flag as he restricts you from going for 2nd by trucing.

Thats my 2 cents anyways, and there aren't any rules regardng this.

The only rules are:
General Rules

Do not use pornography avatars
Do not harrass people
Do not use hate language or avatars


Game Rules

Game-to-game favors or alliances are not allowed
Play only one account at a time

if a truce was made AFTER you flagged you have the right to counter and probably should, when player A truced, he's taking away a possible 2nd from you and therefor cancel the flag

If you're stupid enough to flag someone, you're his bitch.

false marius. PGA is cheating. Shared accounts are also cheating. Those are the rules that exist but aren't written. :)

Serious answer without any wishy-washy:

You did nothing wrong.

Do whatever you can to get the best position possible. Just make sure you weigh metagame consequences as well. If several of the players view this as a stab, and you play with them a lot, then it might not be worth it.
