Thanks to Matilda. Unusual Prize: felt challenging, but solving time wound up far shorter than the norm. Most of the thematics were write-ins, which helped a great deal [for instance, (10,24,26) was second one in]. Agreed on iffy clues, but there were several witty highlights.
FOI 2, LOI the one word rogissimo didn't know at all (I assume); neither did I and Google was required.
COD 21 over 8, 4, (15,23) and 28.
