Best to have tricky situation reversed (4)
I believe the answer is:
tops
'best' is the definition.
(I've seen this in another clue)
'tricky situation reversed' is the wordplay.
'tricky situation' becomes 'spot' (I've seen this in another clue).
'reversed' says the letters should be written backwards.
'spot' reversed gives 'TOPS'.
'to have' acts as a link.
(Other definitions for tops that I've seen before include "Betters" , "spinners" , "Caps; outdoes" , "Surpasses; toys" , "Big tents" .)
