Aging_Arbiter's post in 2 man system positioning on a small diamond was marked as the answer
On a small diamond, you are outside. If on a bigger diamond and on the inside, I have found that taking a half step or so in either direction (left/right) or even up towards the working area from b/c, often clears their line and doesn't put me out of position. I'm sure we will hear a lot more suggestions from a lot more qualified people on here in the very near future.

Yes, I just plagiarized @Rich Ives because it wouldn't allow me to "quote" from another thread.........
