The bidding was straight forward, S opened 1, and N replied 1 , and then S rebid 1NT, which N raised to 3NT

W led the 4 , 4th highest in the suit. Make 9 tricks in 3NT

There is a trap . If you put the Q up on the first trick you cannot get back to dummy when you need to,, so win the first trrick with A. Tackle the suit, and E will hold up  the ace until the 3rd round, Then lead s to return to dummy for the established suit . On any return lead by E you always make 9 tricks
