We can have flag for "future"
That mean.
Lots of time we have one dominant player and 2 other players who fight for 2nd position.
Sometimes dominant player are fair and let other two to fight for 2nd position but sometimes he dont.
With my idea player can flag in "future" so dominant player cant attack him but also that player cant be first.
That will help also against PGA and truce because dominant player cant help his "truce friend"
