If you don’t know what the offset position is then you really should just stop with any and all CTE discussion on your part.I don't see how that in itself is useful. You said this narrows the shot down to half the cb and half the ob. If you can't discern more than that just by looking at the balls you don't belong at a pool table. What does "offset position" really mean? Offset compared to what -- the shot line?
But if you’d like to actually try then start by standing behind the inside edge of the cb in relation to the cut as opposed to being a noser. And for clarification being a noser is not a bad thing if that’s the way you prefer to aim.
