### Solution

 NORTH ♠ K J 10 ♥ J 9 ♦ A K Q J 5 ♣ 7 4 2 WEST ♠ 5 ♥ A 7 6 5 4 ♦ 8 7 4 3 2 ♣ 8 6 EAST ♠ 7 6 4 3 ♥ K 10 8 2 ♦ 10 6 ♣ K Q J SOUTH ♠ A Q 9 8 2 ♥ Q 3 ♦ 9 ♣ A 10 9 5 3

X-RAY VISION. To avoid allowing declarer to get early heart discards on dummy's diamonds, East should signal encouragment in hearts (with the ten, if high cards are used as encouraging). After winning the second trick with the heart king, East should visualize declarer with 5=2=1=5 or 5=2=0=6 distribution and all the missing high cards (for the opening bid). Any defense will suffice against 5=2=0=6, but if South is 5=2=1=5, East must shift to a diamond (preferably the ten, in case declarer's singleton is the nine) to prevent South from using the bulk of dummy's diamonds. If East instead leads a club or a spade, declarer has ten tricks: five spades, four diamonds and one club.
