There are 2 cards left in the deck, and 2 clues available. No one has any clued cards.
What action should Alice perform?
Alice sees the red 3 in Cathy's hand and the red 5 in Bob's hand.
If Alice has the red 4 in her hand, then the situation is simple: the team will clue the red cards and then play them.
On the other hand, it is possible that both red 4s are still in the deck. In this case, there would be no time to play the 5 after playing the 4.
Thus, Alice should discard. She is guaranteed to either have had a red 4 in her hand, or to draw one of the copies.
(For the purposes of this example, we assume that it is extremely unlikely for Alice to be discarding the red 4, since the team would have likely Chop Moved it earlier on.)
After Alice discards, Bob can Finesse the red 3 by cluing Alice's red 4, and then the red 5 can play in the subsequent round.
