My understanding:

A hole can have a diameter of up to 1/3 the height of the board so long as
it is not located in the center 1/3 of the board, in horizontal members. I
don't remember how big it's allowed to be in the center. You may also notch
a board, I believe up to its thickness. (A 2" notch in a 2x10. I think.)  In
vertical members, the hole can be located anywhere, but if it is closer than
1/3 of the board height to the edge, you must use a nailing plate. I use
them everywhere anyway.
