Finally cracked the endgame puzzle I kept failing

I kept losing this one endgame position all week — two tiles left, opponent has an E, and I had a Q stuck with no board play. Finally realized the right move was to dump the Q for 4 points and give up the 10-point swing, because the alternative was spotting them a free bingo lane. It's not the fun answer, but the math doesn't lie. Won the game by 2 after all.
