Editing Losing-Trick Count (section)

==Refinements==
Thinking that the method tended to overvalue unsupported queens and undervalue supported jacks, [[Eric Crowhurst]] and [[Andrew Kambites]] refined the scale, as have others:
* AQ [[doubleton]] = ½ loser according to [[Ron Klinger]].
* KQ [[doubleton]] = 1 loser (obvious).
* Kx [[doubleton]] = 1½ losers according to others.
* AJ10 = 1 loser according to [[Harrison-Gray]].
* KJ10 = 1½ losers according to [[Bernard Magee]].
* Qxx = 3 losers (or possibly 2.5) unless trumps.
* Subtract a loser if there is a known 9-card trump fit.

In his book ''The Modern Losing Trick Count'', [[Ron Klinger]] advocates adjusting the number of losers based on the [[Hand evaluation#Control count|control count]] of the hand believing that the basic method undervalues an ace but overvalues a queen and undervalues short honor combinations such as Qx or a singleton king. Also it places no value on cards jack or lower.
