Which clues are available to Alice?
Which clue is the best to give?
Alice has the following clues available:
She can 5 Save the blue 5. This is safe, but does not get any cards to play.
She can give a Play Clue to Bob's red 1 (with either red or 1). This would be a 1-for-1.
She can give a Play Clue to Cathy's red 2 (with either red or 1). This would cause a Finesse and would be a 2-for-1.
She can give a Play Clue to Donald's red 2 (with either red or 1). This would cause a Finesse and would be a 2-for-1.
However, since both red 2's are on Finesse Position, if Alice initiates a Finesse with a red clue, both Cathy and Donald will mark their red card as possibly the red 3, leading to an Ambiguous Finesse.
Thus, the correct way to initiate the Finesse is with a number 2 clue, which does not cause any ambiguity.
Is it better to use Cathy's red 2 or Donald's red 2? Since Cathy already has a green 1 to play and Donald has an important card on chop, the best clue for Alice is to clue number 2 to Donald to trigger a Finesse.
