I'm surprised by this extensive discussion of 38A - I got it early on, and in Chambers it clearly refers to Broom.
Instead, my problem is the NE corner - apart from 8D, this is barren. Any tips eg 5A?
I also have several solutions that I don't understand eg 11A, 21A, 39A, 4D...
As for playing Battleships, that still seems a long way off!
