The Courier-Mail - - SPORT - with Richard Ward

GOOGLE tells me that com­puter tech­nol­ogy is nowhere close to be­ing able to repli­cate top bridge play­ers. One of the rea­sons is that hu­mans are able to de­velop an in­nate in­tu­ition re­gard­ing what in­for­ma­tion is im­por­tant – se­lect­ing from what hap­pened and what did not. So far com­put­ers are not so good at mak­ing th­ese neg­a­tive in­fer­ences. When it comes to bridge tech­nique how­ever, the lat­est pro­grams make very few mis­takes.

This hand fea­tures a com­puter pro­gram, “Bridge Baron”, ac­cu­rately de­fend­ing a hand against “Mi­cro Bridge”. THE spot­light was on West’s cir­cuits to do ev­ery­thing right – which it did! – start­ing with a trump lead, the only one to give the de­fence a chance. De­clarer won, and with the di­a­mond ruff pos­si­bil­ity now gone, drew trumps and led his sin­gle­ton spade which West took im­me­di­ately with his ace. The di­a­mond exit went D3-6-Q-A. On the run of the trump suit, West dis­carded a club and (very slowly – a lot of com­put­ing power went into this de­ci­sion) then the DK and DJ thus avoid­ing the di­a­mond throw-in and the fa­tal club lead away from the CK, which would have al­lowed the con­tract to make. East’s D10 saved the day for the de­fence. Purists will note that, had West ex­ited early on with the DJ, the end-po­si­tion would have been eas­ier to di­ag­nose.
