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.
On how many deals was 4-of-a-major the final contract?
Answer: 248,980 -- or 24.9 % of all deals.
3NT, last month's question, was the final contract on 18.1% of deals. That was the singular most popular contract.
4 alone was 11.7%
4 alone was 13.2%
All three of these pieces of information are not surprising. You'd expect 3NT (the lowest-trick game) to be most frequent. You'd also expect 4 to be more common than 4 (you can bid 4 over 4, but not vice versa). So, 3NT, 4 and 4 combined account for 43% of all deals played.
FYI: 5 Was played on 2.3% of all deals and 5 on 2.9% (So, a game contract in a minor occurred was bid on 5.2% of 1,000,000 deals). That means that GAME was bid on just less than half of all deals played.
Next month's question: On how many of the 1,000,000 deals was a slam (6 or 7) the final contract?
