Bidding went:  

2 - 2

2 NT -3 *

3 - 4

6 - All Pass

2 was strong and artificial. 2 was a waiting bid for opener to clarify what type of strong hand he held. 2 No Trump showed 22-24 balanced. 3 was a transfer bid showing five or more , and 4 was a 2nd suit and a slam try. With all 4 aces and a fit in both responders suits, opener went straight to 6

Small was led...

Declarer won the lead with the J (an error, should have won the ace keeping better communication with the weaker hand, but not fatal) After playing the A and K of trump with right hand opponent showing out on 2nd round, declarer cashed the A of and led a 3rd left hand opponent won and led a D picking up  the Q, but declarer still had to lose a club to the King. Can you see how the hand could be made after the A and K of trump were played? NO Peeking!  OK here are all four hands.

Declarer must also eliminate the Diamonds by leading the J and finessing then cashing the Ace King before throwing left hand opponent in with the trump Q! Then left hand opponent will have to lead a black suit, if a club, declarer has no more losers and if a spade declarer will pitch dummy's small club and ruff in hand!! If you made it you would win the match, go down and, oh well maybe next time. :-}
