Some of the rules are awkward and confusing to someone who doesn't understand them.
For example, you can convey information to your partner, based on how long you take to bid. Technically, you aren't allowed to have that information.
Me - Left Opponent - Partner - Right Opponent
1NT - x - xx - pass
pass - 2C (after long pause) - x - pass (after long pause)
pass - 2D
Explaining:
I played a weak 12-14 HCP NoTrump opening
opponent on my left doubled, showing a good hand
my partner redoubled, saying he also has a good hand (i.e., we got them now)
Rather than letting us make 1NT redoubled, the opponent on the left ran out to 2 Clubs.
My partner doubled, because he had good clubs (i.e., we got them).
The opponent on the right passed, but he waited a long time before passing, illegally conveying to his partner that he was not sure if they should stay in 2 Clubs or run.
Taking advantage of that (illegally obtained) information, the opponent on the left decided to run to 2 Diamonds.
So, someone who does not understand the concept of unauthorized information would not understand why I would be disadvantaged.
At a local club game, I would let it slide. At a regional tournament, I'd expect the director to get it right.
