Quiz 24 - Lesson 24 - Links page

1. For which type of contracts can the Losing Trick Count (LTC) valuation be used ?
For all trump contracts

2. Can the LTC valuation be used for No Trump Contracts ?

3. How are short suits being valuated in the LTC method ?
Void = no loser   Singleton = 1 loser   Doubleton = 2 losers

4. How many losers are counted in the following 2 card and 3 card suit holdings ?
 A K = 0 A Q = 0 A J = 1 A 10 = 1 K Q = 1 K Q 6 = 1 K J 5 = 2 Q J = 2 Q J 8 = 2 Q 10 7 = 2 Q 9 5 = half J 10 4 = 3

5. Calculate the Losing Trick Counts for all trump contract lesson deals in this course, Lessons 5 to 24.

6. What would be the percentage of missed Game or Slam contracts if you had only relied on the LTCs in the answers to the previous question ?
