Law of Total Tricks - Examples

Examples

For example, suppose that North-South have an eight-card heart fit and East-West have an eight-card spade fit. The total number of trumps is 16 so the "law" says the total number of tricks is also 16. That is, if North-South can take eight tricks playing in hearts, then East-West can take 16 - 8 (also eight) tricks playing in spades; if North-South can take nine tricks in hearts, LoTT says East-West can take only seven tricks in spades.

In the diagram, N-S have 9 spades and E-W 8 hearts combined. N-S can make 4 spades (conceding two clubs and heart ace) while E-W can make only 1 heart on a good defense (which takes a trump from QJ, two spades, diamond ace and two diamond ruffs)—the law holds, as the total tricks available is 10+7=17.

Note, however, how minor card rearrangements affect the law:

  1. If the N-S diamonds were divided 4-2 instead of 5-1, with clubs consequently divided 3-3, the available total tricks would be only 8 for N-S + 8 for E-W = 16
  2. If, on the other hand, the E-W spades were divided 3-1 instead of 2-2 (with appropriate minor-suit rearrangement), they could make 2♥, while N-S could still make 4♠, giving 18 total tricks.

    “It is hardly to be believed how spiritual reflections when mixed with a little physics can hold people’s attention and give them a livelier idea of God than do the often ill-applied examples of his wrath.”
