The Losing Trick Count (LTC) is a way of measuring the trick-taking potential of a trump contract without the need to count points. It enables you to calculate the playing strength and the tricks in your own hand, and to accurately estimate the useful tricks in a partner's hand. Put these two figures together and you have the trick-taking capacity of the two hands. Used correctly, the LTC is a vastly superior valuation technique for accurate bidding.
The beginning and end of the book make some useful points about the losing trick count but the middle chapters just seem to me to be padding so that the content becomes the size of a book.
Gerald lent me his book because I expressed a strong interest in it. So I'm studying it. Some of it is just repetitious or doesn't neccessarily apply, but the core hast merit.
