This. The original chain targetting the lesser threat and trying to force the player already getting set back taking another setback to take care of the main threat almost feels like – totally valid according to game rules and the competetive mindse, no doubt, but still – angle shooting. I totally see a “screw you” reaction to that as a valid answer, too, because players are humans.
If I am the target of said chain and the land I have to throw in to “not throw the game” would leave me completely outside a winning situation, You’d bet I will think long and hard who is the actual problem. One of the guys sitting at the table is only trying to win the game as we all are trying. One other is trying to play me while doing so. 🙂
