South leads the J.
East to make 7 against any distribution and defense.
East wins the K and plays off the A-K and the A-K. If either suit splits 3-2, school is out. If both minors break badly, then:
If the minors are in the same hand, declarer arranges to play off the major-suit winners, and that defender will be squeezed in the minors. Declarer could humor himself by discarding a club from east and a diamond from west, effecting a criss-cross squeeze.
If the minors are in opposite hands, the Qand Q are played off. Then the A and two rounds of spades, discarding minors, squeeze whoever holds the long hearts. (If a heart was led originally, then the club queen is played before the diamond queen, leaving the lead in the west hand.)
