Preempts [Watson]

So much has changed in bridge bidding theory since the last comprehensive description of preemptive bidding has appeared in print. These days players open the bidding on lighter values, and preempts, formerly based in at least a semblance of sanity, are now made on the flimsiest of excuses.

This book is a thorough treatment of modern preemptive bidding; not only when to open and with what, but the issues surrounding constructive and obstructive bidding in the subsequent auction.
