Bridge is a game where experts opinions play very special role, which I appreciate! But for this special hand there are 2 possibilities. 1. More probable S's hand similar to the one described by Stefan Ralescu below. Yes, W must play low! Majority of non-experts is going to play high giving the top for declarer. 2. Declarer has third (or even second) ♣K. Then in turn professional low club gives declarer's top.

This is the point, taking into account statistics. More cards, which are going to be finessed by pd's (playing , say 3♥) are in hands of E. And in the dummy there will be no jack, ten or even 9.

1. There exists a carding system (basic in Poland, but known outside our country), in which one leads 9 from 109xx. We could ask about the carding. 2. You accept “horror” with clubs. But only half of horror. Assume E ducked first round of clubs but you still have doubts if he really has the ace. Now is a matter of calculations what is more probable: either W has the ace or W has the second ♠Q?

This looks like a horror, but we must face horrors. If someone has doubts where is ♣A, there is a method to check it: Play clubs! And if they duck, play the second time!

Richard, this problem is very far from easy. Craig's motif is quite deep. In fact he has 75% Chance to win the contract, which is absolutely comaparble with other lines. Yes, Craig can assume that if W will not enter ace he does not hold it!!
