Computer generated hands are the Marmite of the Bridge world. People hold strong opinions about them, and myths abound. The most popular being that the hands are not random but rigged in some way.More
MoreHere is a quick test. Throw the dealing machine into a tub of water. If it sinks, the hands produced are random, if it floats it is witchcraft. A solution that dates from a time when prejudice ruled! So, can logical, intelligent, open minded Bridge players be subject to prejudice? After all we have years of experience to draw on
" I’m a mathematician, they aren’t random" " They are fixed so that they have strange distributions" We use the BigDeal algorithm in use since Olympiad 2000 . This algorithm is the one used by Jannersten’s Duplimate and Bridgesorter; and Dealer4 software. But what does random mean? Let’s start with a definition of “chosen by chance rather than a plan”. Applied to possible hands of 13 cards dealt to 4 players there are 635,013,559,600 possible deals one of which is chosen at random or by chance. It follows that they are not ‘fixed’. There are no predetermined criteria at work to control distribution, they are chosen by chance. This also explains why hands may be generated that are passed out. As there are no predetermined criteria it cannot be possible to stipulate that the deal must be a “biddable” Bridge deal. In fact, that passed out hands are generated demonstrates that the hands are indeed random.More
"With computer generated hands, when you try to finesse, the card is ALWAYS the wrong side! The trump suite ALWAYS breaks unevenly" There can be no predetermined positioning of a card in a possible finesse. I know people are convinced that this is not so. Where do your beliefs and opinions come from? As a Bridge player I am sure that you honestly believe that your convictions are rational, logical, and impartial, based on the result of years of experience and objective analysis of the information you have available. However, we are all susceptible to a tricky problem known as a confirmation bias—our beliefs are often based on paying attention to the information that upholds them while at the same time tending to ignore the information that challenges them.More
