Recent Developments in Bridge Hand Valuations
The Milton Work Point Count (A=4  K=3  Q=2  J=1) has been around for
about a century. Originally introduce by Milton
Work for the games of Whist and Auction bridge he later also introduced it
as the valuation method for balanced hands in contract bridge when this game
became popular.
In due course the Milton Point Count was used by Charles
Goren for the evaluation of all bridge hands by adding to it the
concept of shortage points valuation.
This valuation system has been hugely successful for decades but, as bidding
systems became more sophisticated and competition became evermore fiercer
deficiencies have started to emerge, especially from the late 1980s onwards.
From my main stream (local club level) perspective four issues have arisen during the past 25
years or so :
 The Shortage point valuation does not adequately reflect the
strength of unbalanced hands.
 Statistical analysis has revealed that on average 55% of hand
combinations of 25 points are of sufficient strength to fulfill a Game
contract. In the fierce modern competition environment this has become acceptable.
 Tens are not included in the traditional Milton Point
Count. Statistical analysis has shown that they should.
 Statistical analysis has also shown that Aces and Kings in
balanced hands are substantially overvalued by the traditional
Milton Point Count.
1. Shortage
The concept of The Losing Trick Count was
originally published by Courtenay and Walsh in 1935 and later again by
HarrisonGray in 1961. But it was not until after Ron Klinger's publication of
The Modern Losing Trick Count in 1987, that this (not so) "new"
concept started to become adopted wide spread as a better method (than using shortage points) to assess hand
shapes, especially shortages.
2. The 25 point Game contract
As a result of this finding the Standard (American) Bidding system has by
many players been modified, featuring a 1517 point 1NT opening (instead of 1618), an indiscriminate 12 point minimum opening (in 1st or 2nd position,
instead of 13) and a new suit response at the 2 level with 10+ points (rather
than 11+).
3. Valuation of the 10s
Statistical analysis first published by Richard Cowan ("Applied
Statistics", Journal of the Royal Statistical Society, 1987) and recently
extended by David Jackson & Ron Klinger (Better
Balanced Bidding  The Banzai Method, 2010) clearly show that 10s should
be included in a proper hand valuation system.
The latter authors recommend the Extended Milton Point Count :
A=4 K=3 Q=2
J=1 10=½
4. Overvaluation of A and K in balanced
hands
Statistical analyses (by the authors quoted under '3' above) clearly reveal
that Aces and Kings in balanced hands are overvalued by
10% combined (resp. 6.7% + 3.3%) by the original Milton Point Count.
Queens are about right and Jacks and 10s are undervalued by 10% combined.
Jackson and Klinger propose for Intermediate to Advanced players the new "Banzai Point Count" which accurately reflects the statistical findings :
A=5 K=4 Q=3
J=2 10=1
(Statistics : A=5 K=3.97 Q=3.06 J=1.93 10=0.95)

The Jazclass  Bridge Course
approach
The Jazclass Bridge Course now uses the Extended Milton Point Count approach throughout. This
increases the total points in a pack from 40 to 42 High Card Points, and as a
consequence statistically restores the minimum Game contract requirement
from 25* back to 26 points. This has the following advantages :
 It restores the Standard (American) Bidding System to its
(approximate) original values.
 It reflects the Hand value with greater accuracy than the original
Milton Point Count system.
 It reduces the overvaluation of Aces and Kings in balanced hands by a third : to 6.7%.
 It incorporates the more aggressive Game contract approach
of recent years.
^{25}/_{40}= 62.5% of total trick taking power (ttp) ^{26}/_{42}= 61.9% of total ttp
Obviously the Banzai Point Count is superior to Extended Milton. However it
will probably take years before this system is fully in mainstream use. For
the time being Extended Milton appears therefore the better option, especially
for Beginners and most Intermediate players.
However I recommend that
Intermediate players have at least a working knowledge of the Banzai Point Count, so that in borderline decisions
of balanced hands it can be used as an additional valuation check. Generally it is also useful to be aware that balanced hands containing mainly Aces and Kings are overvalued in point counts and those including several Jacks and/or 10s are undervalued.
With hand Combinations containing at least one unbalanced hand it is best to use a combination of
Extended Milton (HCP) and the Losing Trick
Count (LTC) or the valuation index (vi) I recently developed myself.
Note *
As there are four 10s in a pack any hand should on average include one 10. Many 25 point hand combination (as valued by the old system) will therefore on average include two 10s and as a consequence have 26 points when valued using the Extended Milton Point Count. (It is tempting to speculate that the 45% of old 25 point hands which statistically don't make a Game contract are in most cases perhaps deficient in 10s.)
