mark_gap

Flag a node as an open knowledge gap that the other player should fill, keeping its kind. Costs one of your 6 moves and ends your turn. During your opening (gamePhase "opening") it is free instead, and the opening ends after 3 such moves or when you pass. You cannot mark the root, a node that is already a gap, or a node that already has a resource or skill directly under it. Every gap still open when the game ends costs 5 points, so mark gaps you expect to be filled and give a reason.
