Found this pretty tough today! I'm short of three. Please help.
29D Fake welcoming battle being this (6) -O-A--
39A Movement of platform restricted by barrier (7)
46A Silly to draw net tighter (5,2) C-O-E -N. If the answer to this is CLOSE IN, where does 'silly' come into it - or is that meant to be me!
Thank you very much.
