Time to sacrifice a Knight. The skipper of the boat.
Iran's move. Will they take the Knight or will they move to further strengthen their attack?
A chess game indeed.
Either you don't win much at chess, or you just aren't very good at analogies. I sure in the heck wouldn't sacrifice a knight just to be sacrificing, unless capturing another knight or a rook. I don't see how this sacrifice is up to the potential gain unless Iran has incredibly good board position. Iran has sucky board position.
