20: Power of Deduction

09 Nov 2013, by abbiefeuer in Bridge Bites

This deal follows continues the month’s theme of counting the opponents’ HCP.

Good Declarers also routinely count the HCP that appear in the opponents’ hands … closely related to Remembering the Auction.

This is not the most swashbuckling auction ever to appear in Bridge Bites but the deal does provide a test for Declarer’s powers of deduction.  Cover up the E-W hands if you would like to test your own powers.

 Both Vulnerable 

20 Bridge Bite Hand

West leads the ♣J won by East’s Ace and it takes half a nano-second for East to find the ♥Q shift.  You could duck Hearts twice, hoping that West has the doubleton ♥A, but that would give East 5 Hearts and he would be unlikely to sell out to 1♠ in that case.  So, you hopefully play the ♥K, taken by West’s Ace.  Two more Hearts are won by East’s ♥JT, then a Club which you win.  The ♠A and ♠K are cashed, followed by the ♠J to East’s Queen (West following).

Back comes East’s last trump, and decision time has arrived!  You’ve already lost 5 tricks, and must avoid the loss of two Diamonds if you are to make your contract.  A Diamond to the Jack?  Or a Diamond to the King?  Do you have your guessing shoes on?

Guess?  What guess?  Let’s reflect upon East’s bidding.  Oh, that’s right, he didn’t bid – which is the whole point of this hand.  So far East has shown up with ♣A, ♥QJ, and ♠Q.  That’s 9 High Card Points (HCP).  Can East also have the ♦A?  Absolutely not!  He passed originally, that ♦A would give him 13 HCP and too much for said Pass.  So, you lead a Diamond towards the board, West smoothly plays low, and you rise majestically with the ♦K.  Making 7 tricks thanks to a little deduction.

Post Script: Upon winning the ♥A, West would have done better to shift fiendishly to a low Diamond, putting Declarer to the test in that suit before all the clues had been collected!
