I'm reading Clyde Love's Bridge Squeezes Complete, but I can't understand a few exercises, eg exercise 2 at page 181, a repeating squeeze.
Love says: "On the last trump [♠9], dummy discards the ♣Q (or a diamond). Now if East parts with a heart or a club, the result is straightforward. If he discards a diamond, however, a Vienna Coup will be essential for the heart-club squeeze: that is, declarer must cash the ♣A at Trick 9."
Let's discard the ♣Q, cash the ♣A, and try.
Clearly, you can't lead the ♥A, but if you cash the ♦K there is no heart-club squeeze because dummy wins the next trick and East can discard the ♣K.
As far as I can understand, dummy must discard a diamond on the last trump (dummy could discard the ♣Q if the diamonds were J6/K9.) What am I missing?
Plus... it's free!
