Solution

North wins and leads the 10, covered by East (if not, see the final paragraph) and South.  South leads the 8, North overtaking even when West plays low.  The 9 is covered by East and South, who leads the 5, North winning as cheaply as possible.  North's 6 is allowed to hold (best), West discarding a diamond.  South comes to hand on the last club, forcing West to discard another diamond, coming down to three of each major suit:

 ♠ A ♥ 543 ♦ AJ or A6 or J6 ♣ none ♠ KJ10 ♥ J109 ♦ none ♣ none ♠ 8765 ♥ 87 ♦ none ♣ none ♠ Q32 ♥ A ♦ Q7 ♣ none

South's diamond lead now subjects West to a seesaw squeeze.  Which diamond South leads depends on which one West played on the second round:

A.      If it was the 4, South leads the 8 and North wins with the J or A depending on which major suit West now unguards.

B.      If it was the 9, South leads the 8 and North overtakes or ducks.

C.      If it was the K, South leads the Q and North plays the 6 or J.

The ace of the unguarded suit is followed by the last diamond to put the lead in the hand that now establishes a winner in that suit with the other ace as entry to it.

A fourth variation arises if East ducks the first two rounds of clubs.  In that case South comes to hand on a club, forcing West to discard a diamond.  This time South leads the Q, which holds, followed by a diamond to North's J.  The last club forces West to discard the K, allowing the seesaw squeeze to follow as before.
