Could bridge be called this complicated? (6)
I believe the answer is:
tricky
This clue is a double definition.
'could bridge be called this' is the first definition.
(the card game bridge involves 'tricks')
'complicated?' is the second definition.
(I've seen this before)
(Other definitions for tricky that I've seen before include "Complicated" , "Problematic - deceitful" , "Crafty, foxy, slippery" , "Crafty, cunning" , "Crafty or difficult" .)
