Rule book and Case book correlation?

[jTheUmp]

They go together.

The rule book is just that, a book containing the official rules of the game.
The casebook is a supplemental that is intended to help you navigate through most of the "really weird" situations that you'll potentially encounter in a game (and that have almost certainly been encountered by someone, somewhere, long before you got here).

Oftentimes, the casebook plays will reference several rules which must be combined to bring you to the approved ruling.


Using your example, rule 1-3-2 says this:

Pretty simple, right? All this rule does is specify the division line.

Here's the casebook play:

RULING: The area within these lines need not be of one color, but the continuous line must be clearly visible.

In other words: "The division line has several different sections to it that are different colors... is that legal?"
Answer: "yes, that's legal, as long as the line is clearly visible"
