Chuck seems a bit pushy (3)
I believe the answer is:
shy
'chuck' is the definition.
(both can mean to throw)
'a bit pushy' is the wordplay.
'SHY' is hidden within the letters.
But, I'm not sure how this is indicated.
'seems' is the link.
Can you help me to learn more?
(Other definitions for shy that I've seen before include "Retiring; fling" , "cast" , "Timid and self-conscious" , "Bashful or timid" , "Quick throw" .)
