Rocket Science


13th May–Board 14. Love All. Dealer East.
It was disappointing that so many pairs failed to bid the laydown grand on the hand featured below where there were in fact fifteen tricks ‘on top’. And yet it was hardly rocket science.

S 7 6
H J 10 6 4

There are a many ways you might approach this hand but the one shown above has the merit of simplicity. 4D is a slam try in diamonds and East shows his approval by cue-bidding the ace of spades. 4NT is RKCB and 5C owns up to all the missing key players and it is hard to imagine a hand where all thirteen tricks cannot be taken at this point. However to make assurance doubly sure 5NT asks for extra kings and 6H shows 2 on a step response principle. So West knows his partner has the ace and king of spades, the king of hearts, the king of diamonds and the ace of clubs – and that comes to thirteen tricks!
