I believe the answer is:

jerk

I'm a little stuck... Click here to teach me more about this clue!

'suddenly throw' is the definition.
'jerk' can be an answer for 'throw' (thesaurus). I am not certain of the 'suddenly' bit.

'jack queen and king' is the wordplay.
'jack' becomes 'J' (playing card abbreviation).
'queen' becomes 'ER' (short for Elizabeth Regina ie Queen Elizabeth).
'and' means one lot of letters go next to another.
'king' becomes 'K' (chess abbreviation).
'j'+'er'+'k'='JERK'

Can you help me to learn more?

(Other definitions for jerk that I've seen before include "preserved beef" , "Yank, idiot" , "Jolt; tug" , "Tug suddenly" , "Twitch" .)

I've seen this clue in The Times.
