 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

    Answers

  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 ?
    Of the 66 trump contract deals analysed only 5 had a LTC which matched the actual performance of the deal.   41 deals , or 62% are undervalued and only 5 deals are overvalued compared to the actual play results. 29 of the undervalued deals (or 44%) would have missed a valid Game or Slam contract if you had only relied on the LTC method.

  7. On what assumptions are the Trick value shortage points (TSP) based ?
    Void = 3 winners   Singleton = 2 winners   Doubletone = 1 winner

    Singleton = 6 TSP   Void = 8 TSP
