[Eric Landau]
Your obligation is to tell them what you know.  It doesn't matter
whether "you can work out the meaning of a bid"; what matters is
whether you have in fact done so.  If you haven't, you are not
obligated to do so on the spot for your opponents' edification.

[Nigel]
I'm beginning to understand Eric's argument. Quite often you can deduce 
enough for *your own* purposes. Why should you continue your deductions 
to answer opponents? Well, let's just say that I think you should :)
