So we are on critical situation. You need either to give yellow who seems good, or do something unconventionnal. It depend of the position of your chop too.
Playing #3 (=card in position 3 with 1 leftmost) is a possibility for make a play of y3 on some situation.
Or give an empty clue on a no double discard situation (depend what happen last turn) with someone who trust you for save 2 card.
Or an off discard.
Guess I would do yellow with random player, and perhaps an empty clue with someone I know.
edit: But even if there is a possibility of double discard of the same card, I would not do it with only 1 clue left, so it's still fine.
