Numbers in brackets give the number of cells in the entry. In some answers which are one letter longer than the available space, two letters must be entered in one cell. Some other clues contain misprints of one letter in the definition.
18 A. Score hard boards extremely softly (4)
???p
35 A. Visually rich, retiring guards glare (7)
??s?ur?
(Not 100% sure of the 's').
Thanks for any help.
