Now that there are massive data bases available, it should be possible to evaluate competing styles of bidding.
What percentage of boards are opened by dealer? Separate the data into four subgroups: both, none, favorable, and unfavorable. Is there a significant difference in opening frequency?
Is there a massive database on team play? On boards where one dealer opened and the other dealer passed, which side was the net winner of imps?

TIA,

hi jogs,

I believe you are right inasmuch it could give a general overview, but there are so many other factors involved such as strength of opponents, action by opponents, system and conventions used by both sides, etc., etc., etc. that it will give an indication but will not be conclusive. Just too many variables to explore.

In chess, it would be far, far easier as every player is rated, and there's only the chessboard and the clock. Alas, for bridge it is not as simple as that, I personally feel

We must start slowly. Every journey begins with a first step.

Yep. And if you really do have a huge database, all of the other factors should get balanced out.

[jogs]

Those factors never balanced out. They do play a smaller role.

It's been over ten years since Mike Lawrence introduced short suit totals. Yet most experts seem to have ignored his contribution to the theory. Granted it is very difficult to exchange this info during the auction.

Some interesting data on opening bid frequencies.
