Norm Wiggins wrote a book called, "Boards, Blots, and Double Shots," in
which he coined the term "boardage" to mean having at least two more
home-board points made than your opponent has. When you have boardage,
it's time to look for bold, pure plays. Here, there is no urgent need
for X to anchor; he should stay back on the 24pt for more contact.
