How do you decide which letters to fill in...sometimes more than one letter will do...eg in 5d ..I have BA?T so lots of alternatives. Also 37a ?
I think the filled in letters make a shape (same as the phrase under the grid) ...but do the letters also spell something out?
26d One about to stop husband's excessive desires ?AN?A? looks like manias ?
44a God's taking educated guesses for the old fashioned (6) ?RE??S
29d Crippled foreign character (5) ?AME? lamed?
