Dormer on Deduction by Al Dormer.
This builds on the foundation Mike Lawrence built in How to Read Your Opponents Cards (HTRYOC). It goes beyond the fundamentals like counting HCP and seeing where the unseen honors are. It covers more advanced topics such as:
- empathize with pard - why did pard make such and such a play? Is it becaus ehe didn't have enough information? Can you help him out? There is an example hand against an enemy contract where you get in. You have a stiff, and the Ax of trumps. If you lead the stiff, pard may duck, thinking its a doubleton and taht you have a trump entry. What can you do to clarify the situation?
Cash the Ace of trumps, then lead the stiff. This shows pard that there is no point in not winning the ace and continueing the suit. Of course both partners must be on the same wave length! Thus both should read the book!
- look at the enemy discards. usually you want to keep parity with dummy, especially if dummy has a suit like AQJ7. If a defender discards in that suit, the chances are that its safe for them to do so, meaning they had more than 4 cards.
- just like HTRYOC there are chapters on clues form the bidding and opening lead
- clues from how a suit is played. Why is declarer not playing on Spades with KQJ96 in dummy in a 3NT contract? Because he has the ace, and needs to establish one more outside trick.
- beware of gifts - why did the opponent give you an optio? Such as allowing you to reach dummy to take an otherwise impossible to take finesse? OR not force you to ruff with Dummy when Dummy holds Ax in trumps
The negatives - some of the bidding is obsolete. He has one glaring error on one hand, where his suggested play is wrong. Some of the signals he uses are not used in the USA (which is the center of the universe, hence the book is wrong
Some of the inferences are a bit thin, and I would hesitate to draw conclusions, especially against non-experts who might not card correctly anyway.
I consider this an intermediate+ level book.
All in all , a great book, I rate it an A.
