Opponent’s options: Bingos in columns a, n, or o
Candidate plays: INFORM 2j (33), FIORD a6 (27), FUN n2 (29), UMBO 1a (27), JO 2f (14), NO 14k (2)
Potential plays on next turn: Same plays, plus whatever opponent gives you

Subgoal: Minimize the number of bingos that your opponent plays that will score enough to win the game.

Resolution: In Puzzle 45, you are ahead, but there are two places to bingo: column a and columns n/o. There is no way to block both bingo spots on this board. However, you can make a sort of delay play by playing NO 14k (2), setting up your F. After this play, nearly any bingo will afford you a high scoring play, frequently outrunning your opponent.
