The Law of Total Tricks 



JeanRené Vernes first 'invented' the Law of Total Tricks in 1968. The Law states "The Total Number of tricks available on any deal is approximately equal to the Total Number of trumps" 
Where 'Total Number of tricks' is the addition of the tricks that can be made by NS and those that can be made by EW when both are playing in their best trump suit. The 'Total Number of trumps' is the sum of the trumps held by NS in their suit and the number held by EW in their suit. 
Although known about for more that twenty years, The Law of Total Tricks was not widely recognized until it was much publicized by Marty Bergen and Larry Cohen in the early 1990's. 
A popular, but not quite so accurate, version of the LAW is that in a competitive situation, where the points are roughly equal between the two sides, it is correct to compete to the level of the combined number of trumps held by your side. 
Let's have a look at a typical ‘LAW' deal with everybody vulnerable:  

East A 
West 
North 
East 
South 
You hold this East hand A, should
you compete with 3♥ or not? 






♠ 
852 
1♥ 
1♠ 
2♥ 
2♠ 
The answer is (probably) no.

You appear to have only 8 combined trumps and 3♥ will probably go down, likely doubled.

South 
Now let's change the hand slightly so that you have an extra trump. This time you know that your side has 9 combined trumps and you should compete to 3♥.

If you exchange South's ♥4 with East's ♦2 East then has hand E and EW can make 3♥ but NS can still only make 2♠.
