Money Play. How should Red play 52?

This is all about tempo. White cannot be allowed his whole roll next turn. Red must hit 3/1* with the 2. After that the only logical 5 is 9/4.

Making the full prime with 9/4, 5/3 comes a close second as there is nearly always value in a full prime but 9/4, 3/1* is best.
