Bridge: Count the shape for play

Bridge 9-30

Henry David Thoreau, an author and poet who died in 1862, said, “It is not worth the while to go round the world to count the cats in Zanzibar.”

I always thought that the key stat about Zanzibar is that the whole population of the world could stand on it. However, for a bridge player, this should become: It is worth the while to count as much as you can on every deal.
