Plan A will not work, ruffing clubs in dummy, go to Plan B. Plan B is always blame the victim (partner) but let's try something else this time

and make the hand.
Plan B=We need to see Plan B which is, hearts are 2-2, D are 3-2. LHO has the Ace of trumps. Hope that LHO will not tap dummy, if LHO does then go to Plan C. So at trick one we win A of S and pitch Club not a D. Trick 2=small trump to K of H.
Plan C= if lHO leads small club we pitch and win K of clubs in hand, If LHO leads A of clubs we go to Plan D.
Plan D=Ace of clubs then pitch spade in dummy and follow low in hand. Next trick is another club, again we pitch in dummy and win K of clubs in hand, this requires RHO to have 2 clubs...they Do!.
With plan D we win 2 spades, 2 D, K of clubs, 5 heart tricks in our hand and ruff one club in dummy for 11 tricks.
