On board 2 a good 6 spade contract was reached at both tables.  Without a heart lead the hand is easy. 

An elimination play almost found by Shark Bridge.  After a heart lead, declarer has to ruff two hearts in dummy and get back to his hand to pull trumps.  Heart to the Ace, heart ruff, club Ace (cashing only one club), diamond Ace, diamond ruff, spade K, spade Q to West's Ace, and a club return puts declarer in dummy and promotes West's trump 8.  On this hand, declarer had to cash two clubs earlier, 'eliminating' clubs as an exit from West.  However, if the hand with the Ace of trump has three clubs, he could give partner a club ruff.  Also, declarer's play wins if the hand with the trump Ace has a singleton club, while the winning line would fail off the top if either opponent has a singleton club.  At least it was a plan.

Against Q-Plus Bridge, Shark Bridge overcalled 2♥ and doubled the final contract.  This gave declarer a chance (?) to steal a trick.

Placing the ♥K with East, and long trumps with West, a simulation gave declarer little chance after the heart lead. Even so, the attempt to steal a trick seems extreme...but robots will try anything that a simulation says might work.  Declarer led the ♦Q at trick two and let it ride. When it lost Q-Plus Bridge was down two.  Shark Bridge's aggressive bidding gained 9 IMPs.

Q-Plus Bridge outbid Shark Bridge on board 10.

Shark Bridge South opened 2♣, and North tried for slam rather than bidding 3NT at it's second turn.  After three rounds of diamonds, there was no place for for an eleventh trick. 

Q-Plus Bridge easily found 3NT and make 11 tricks when the opening lead was ducked to declarer's queen.

On board 16, both sides reached a laydown slam.
