The contract was 4S.
I played a ♣ to the K and returned a small ♣ taken by East with his ♣Q.
Now I had a brain misfunction and thought that ♣J was high and claimed all tricks.
East has to return a ♦ to AQ in dummy. Will EW get another trick or not?
(Maybe I even said in the claim that a ♦ goes on the ♣J, but if East has to play a ♦ it would be very illogical not to play ♦A iso ♣J?)
