Smart trick for duck (5)
This could be a double definition.
'smart trick' is the first definition.
'dodge' can be an answer for 'trick' (I've seen this before). I am not certain of the 'smart' bit.
'duck' is the second definition.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for dodge that I've seen before include "Avoid cunningly", "Avoid by sudden move", "Avoid by sudden movement", "Avoid or attempt to", "Elude, sidestep".)
