I was reviewing a game tape last night, and the first thing I noticed is that my very first call of the game may have been bogus. I was at lead and called a shooting foul on the far side of the lane (inside the lane, but much more than halfway across). I began charting these and I counted three calls across the paint (one way, way, way across GRRRR

)
I should say this was a two person game, and in two person I have always considered the paint to be a dual coverage area. But after starting to work some three person games, I'm starting to wonder if I should be more conservative in "calling across the paint".
So how do you divide coverage in the paint in a two person game?
