Consider the following hand, which is an improved version of a problem composed by Paul Barden which appeared in an early Newsletter:
The defence finds the annoying line of A followed by 9 to the 10 and K, and a low trump from East, on which West throws 7. Declarer is now a trick short, but finds the brilliant shot of a low club from dummy, won by East. A club is returned to dummy (J squeezes West!) a club is ruffed in hand and a diamond in dummy, leaving the position on the front cover:
North leads a club and East is subjected to what Paul Barden
reliably informs us is a `new squeeze', which has not been seen
before in Bridge literature. Another world exclusive for the CH
(a) Clearly trumping is hopeless as we make 3 trumps, A and the long club.
(b) If East throws 5, we ruff and duck a heart to the bare ace. A trump is returned, but we cash dummy's winners and exit with a heart. West must lead to our A.
(c) So East throws a diamond. We ruff, play A and ruff a diamond. North leads a winning club in this 3 card ending:
East must ruff, we overruff and West, caught in a vice, must throw a heart. A heart lead now establishes dummy's 6.
If you managed to analyse that out from the diagram on the cover, you have my (JM) sincere congratulations! There are many subtleties in the play of the full hand. In particular, note that playing A too early fails, as East throws a heart at the end and then forces dummy.
