Opponent’s options: Row 12 and row 15 plays
Candidate plays: LAVAGES 15h (36), JAGG 11k (26), JAR 13l (20), JAIL 12l (24), AG 2j (3)

Subgoal: Outscore your opponent in the endgame given a good draw (and a really bad opponent’s rack)

Resolution: In Puzzle 32 the game seems lost, as you are well behind on a board with limited scoring opportunities. You need to hope to draw well, such as drawing the U (leaving your opponent vowelless), the S, and/or the H.

The AG setup lets your opponent block without giving yourself a good chance at having your opponent draw badly, while LAVAGES gets rid of your valuable vowels and JAGG leaves your opponent an open A which they can use to score well and get rid of high scoring consonants.

JAIL and JAR are both reasonable.  JAR leaves yourself an A hook, but it seems unlikely that you will leave yourself a good play using that hook, however, it leaves one in the bag, leaving your opponent a much harder road in the endgame and making it likely you will get to play an out-in-two.  Because of endgame timing, JAR is a slightly superior play.
