I am afraid that there will be a substantial minority of  
directors, who, like Paul Lamford and Alain Gottcheiner, reject  
arguments based on the balance of probability.
 
[lamford] Not so. For a bid to be demonstrably suggested, I offered the  
opinion that a split view as to whether it was suggested at all made it seem  
improbable that it was demonstrably suggested. There is nothing much wrong with  
the word *demonstrably*. Let us say that LHO opens 5C and partner passes after 
a  BIT, greater than that allowed. RHO passes. Partner must have been  
considering bidding or doubling. I would say that the bid that caters for the  hand 
partner is most likely to have for a BIT is the one that is  demonstrably 
suggested. Assuming of course that our bid is not automatic. So the  balance of 
probability comes into the equation very  strongly.
