You should play 4S.  On any lead you have six spade, two heart and one club tricks.  The best lead for the defence is a club.  Win this in dummy and play a Spade to the Jack and a diamond towards table.  West wins but you will then either get a club ruff, or a third heart trick or be able to play the Diamond Queen off dummy throwing one loser and discard another on the Diamond Jack.
