Daniel Neill's excellent system page has been down (at least for me) for quite some time now.
But I do believe I have read that partnership bidding book. I got it from Daniel's site a few months ago and read it through. It was indeed an excellent read. I learned a lot about the theory of competitive bidding and I believe it to have helped my bidding judgement quite a lot.
One little thing I remember was the reasoning behind why it's a misnomer to think that describing your hand accurately helps your opponent as much as your partner. And perhaps I've bought into that concept (and it's corollaries) over-zealously, but I have yet to be convinced why it's invalid.
So, regarding pre-empting, I guess I feel that even if the opponents rate to have the majority of points, your partner still has calls to make regarding doubling a doomed game, sacraficing, or just keeping quiet. Also, your partner knowing your defensive values or lack thereof can be helpful to him every bit as much as declarer, particularly as partner will (initially) be more informed as to which values, and not just how many.
I do know of some of the advantages of being more liberal. When opps have the majority of the points (and therefore "own" the hand), they should be bidding slowly and we should be bidding as high as possible, as quickly as possible.
So yes, I acknowledge that you should be more liberal in such situations, such as when your in third seat, or when the bidding and your holding suggests partner is broke, etc.
However, I think that people jump on the whole "3rd seat" concept way too much. I think people over do it because:
- People love bidding
- People love punting
- People think it's fun to annoy the opponents and generally get the balance wrong between fooling your opponents at the expense of fooling your partner.
The difference between theory and practice is that in theory, there is no difference between theory and practice, but in practice, there is.
