To give you an example:
Playing pairs you open 2♥, which in your methods shows a weak two-suiter (five hearts and 4+ in any other suit). Although your opponents have a combined 24 HCP's, they have chosen not to bid.
The a priori odds of a 3-3 break are about 36%. Given that both opponents passed, do you now expect the odds of a 3-3 break to be greater or less than 36%? (Yes, I know that there are other clues from the lead and early play - but I am interested in the inferences that can be drawn from both opponents staying silent).
