There's been a lot of talk about bridge bidding in these parts lately. A lot of people like to play "straight down the line", to the point where they're mortally offended when you suggest something "risky" but actually fairly commonplace, like a weak no trump, falsecarding, or even (apparently!) pre-emptive bidding.
My question is, is it wise to cleave very closely to a standard systems of bidding, that have been refined through the ages and proven themselves time and again? Or is it well worth it to introduce a bit of craziness into the mix, in the hopes of bamboozling opponents who may be too set in their ways? It seems obvious to me that putting opponents in situations they haven't encountered millions of times before in the course of playing against standard systems might be a good way of gaining an advantage over them.
If odd bidding systems are a good idea, then what examples of them can you give, and how did they confer an advantage? I have a couple of anecdotes of my own, but I'll provide them as an answer...
