South plays in 6♠, East having doubled the bid of 5♣. West leads the ♣10. Despite the potential defensive ruff, the declarer must duck the lead to East's queen in order to rectify the count. East returns a trump (a red card would reduce the situation to other sorts of squeeze ending). The declarer has 7 spade tricks, a heart, a club, and two diamonds. The twelfth trick can be obtained by compound squeeze: assuming only East guards clubs, he will have to ultimately unguard one of red suits on the first squeeze card; that suit will serve as the "common suit" for the latter double squeeze. The declarer draws trumps, cashing the ♣A in the process for a Vienna coup. When declarer leads the sixth trump (♠5), the position as on the right diagram is reached.
West discards a heart, dummy a club, but East now has a problem, as he must discard one of red suits:
- If he discards a diamond, declarer can now cash ♦K and ♦A. On the last spade, a classic double-squeeze position occurs, where both players cannot guard hearts.
- If he discards a heart, declarer can now cash ♥A and ♦A. Again, a double-squeeze is executed, as both players cannot guard diamonds.
The motive is similar to the one in guard squeeze – East is squeezed in three suits and forced to abandon the help to his partner in one of them.

Famous quotes containing the word example:
“Our intellect is not the most subtle, the most powerful, the most appropriate, instrument for revealing the truth. It is life that, little by little, example by example, permits us to see that what is most important to our heart, or to our mind, is learned not by reasoning but through other agencies. Then it is that the intellect, observing their superiority, abdicates its control to them upon reasoned grounds and agrees to become their collaborator and lackey.”
—Marcel Proust (18711922)
