Tough Play Problem

Watching another Cayne match on BBO and saw this really interesting play problem come up. You are in 4S, all Vul, after you opened 1D (Precision) and JEC on your left overcalled 1H.

KQ74 KJ A87 J984

J985 A864 KT K52

The opening lead is the 2 of Spades, which RHO will duck whatever you play. The obvious problem is how to avoid 3 Club losers to go with the Spade loser. But you have real interesting spot cards in the suit to offer a few ways to play it. You also have a lot of entries to each hand to do almost anything you desire in terms of leading them. You also know that the opps are never going to break that suit for you, and you have no real way of throwing them in for it other than a Spade, and with the first round being ducked, you are almost sure any Spade played by you will go A and out a Spade.

Will let you decide on line of play, then say what the declarer here did and what I kind of think is right.

At the table, declarer led a second Spade, that went A on your left and another Spade. The Heart hook to the J worked, and he now led a Club to the K, loosing to the A and going down 1 when QT were in the other hand.

I think the spot cards in Clubs are the key. If RHO has either of the T or Q, are you not guaranteed a Club trick if you run the 8 off of dummy, covering whatever RHO plays? This only loses when the hands are reversed, and RHO ducks the A twice. But it is at least a 2-1 favourite to win on this hand.

Any comments?
