In Response To: Clocks and Penalties (Gregg Cattanach)

The linked lesson is excellent. One can learn to quickly recognize easily countable clusters and learn to count them quickly. And memorize the count some clusters -- Reference position #2, for example; I'd never add or multiply looking at a 6544321 or 65432 board.

But nearly all the reference positions include some simple multiplication, e.g. #1: "Multiply the midpoint of any 5-Prime by 10 and you have just counted a cluster of ten checkers" -- multiplying X times 10 being somewhat faster than adding X+X+X+X+X+X+X+X+X+X.
