DR suggestions range from 1 to 5.  I agree with those experts who remarked that the hand really plays itself and it's the novel ending that makes it interesting.

Solution

North wins and leads a middle spade, South finessing.  South leads the §J so that three rounds of clubs can be taken ending in North, who leads the other middle spade for another spade finesse.  The last two club winners force diamond discards from West and North, hearts from East.  The ªK now exerts a seesaw squeeze on West.

A.      If West discards a heart, North overtakes and throws East in with a spade so that North takes the last three tricks in hearts.

B.      If West discards a diamond, the ªK wins and West is thrown in with a diamond (either immediately or after the ©Q).

The ending appears to be yet another new variation on the seesaw (entry-shifting) squeeze theme. Vincent Labbé and I would be most pleased to hear of any precedent for this ending.

See the solution to Competition Problem #4 for the recommended tabular format if you prefer not to write in English prose.
