In this series, we are analyzing 1,000,000 deals which were played on-line. These deals cover a wide range of level of play and were provided by Stephen Pickett with Bridge Browser.
75% -- a number that might have been guessed. The non-opening side plays 25% of the hands.
Some more trivia (or is it minutia?):
The non-opening side played in a grand slam (keep in mind, it could have been a sacrifice) on only 471 of 1,000,000 deal (note that 10,000 would be 1%, so this is a really low percentage, as expected). Of those grand slams, 26 were a contract of 7NT for the non-openers side. Contrast that to 1,350 contract of 7NT reached by the opener's side.
On the other end of the spectrum, the Opener's Side played it in 1 (that would be 1-Pass-Pass-Pass, in case you are having a bad-brain day) on only 1,997 of 1,000,000 deals -- a fifth of a percent. In case you are really having a bad-brain day, I will tell you that the non-opener's side played in 1 zero times--of course. They did play in 1 (That would be a 1 opening and then the other side buys it in 1) on only 237 out of a million -- a rare occurrence indeed.
What was the most popular contract by each side?
For opener's side, 3NT (as we've already seen in this series), on 165,240 -- or 16.5% of all deals
For non-opener's side, 4 on 31,910 -- or 3.2 % of all deals.
