Bidding:       2NT by West shows both minors (at least 5/5)

                   3C by North = cue-bid of opponent's suit agreeing hearts with good support                            

                    3S by South = cue bid showing a control

                   4C by North = cue bid showing a control

Opening lead = 4S

West surely must have AD and KC for his 2NT bid.  After winning the opening lead & drawing trumps (West having 2, therefore 1-2-5-5 shape), the plan should be a strip squeeze & end-play.

Your next lead is a Morton's Fork play of the 2D from hand. If West wins this trick, the hand is over - cash the KD & the club loser in South's hand disappears on North's QD. Therefore West ducks & North's queen wins the trick. The next play is to cash all the spade & heart winners to reach this position as the last heart is about to be played:

N

 ♦   4 3

  ♣  A 4 

                                                                            W                                                                       E

                                                     ♦  A J                                                                Irrelevant

                                                                       ♣   K J                               S

                                                                                                             ♥   J

                                                                                                             ♦   K          

                                                                                                             ♣   Q 2

West has to surrender when the JH is played as he is unable to protect both his minor suits.
