Tricky one this week with some hard to fathom clues.
33a My college's principal, unrestrained after Oxford honours course (5, 5) G - A - T - C - T - Only thing I can think of is GREAT SCOTT.
20d Green and Liberal coming in to challenge me from below (7) L - E - A - D Again, only thing I can think of is LEEWARD.
32d Point's tougher, extremely hampered by poor pool style (12) - R - A - T - T - O - E BREASTSTROKE is pool style, but why?
Thanks for any explanations, or maybe I've got something wrong.
