Today’s Saturday Stumper

Today’s Newsday Saturday Stumper, by Brad Wilber, is rated G, as in Goldilocks: not too easy, not too difficult, just right, with some beautifully clever clues. The four I liked best: 22-Across, three letters, “Beat back.” 40-Across, five letters, “Inferior cut, to many.” 3-Down, eight letters, “Boxing venue.” And 12-Down, six letters, “Fahrenheit or Celsius.” I especially like the likes of 22-Across, with so much trickiness going toward a three-letter answer.
