The hand makes by taking all the finesses. Watch entries. Play the Aces before taking the finesses. On a Spade lead play the 6  from dummy. On a Diamond lead play the J  from Dummy. 

2. Bidding: South opens 1 ; North bids 2 ; South rebids 2 NT; and North 4 . 
Opening Lead: Q 
Count: 6 losers: 1, 3 , 1 .
Plan: Do not let East win a trick and play Diamonds.
Take the Club and Heart finesses by playing the Jacks from Dummy. Pull trump then dump Diamonds on Clubs. Save the K  as an entry for the winning Clubs. Even if the finesses lose there are only 3 losers: 1 , 1  and 1 .
