Great solve. Lucky 2 for me: AROSE, STEAM. As a competitive Scrabble player, I know all Q words up to 9 letters long. Have you seen the U2 mock-up "I can play with or without U"? Fabulous.
I once won a game by playing out with QIVIUT (the fine under-wool of a muskox). My opponent knew exactly what I had on my rack (tile tracking) but he forgot to block this word.
