2-D perspective can be pretty wild sometimes. Bob, your layouts are helpful additions; thank you.If you send the cue ball off the 6 as far as the 3-10 I think there is no way to keep the 6 by your pocket unless you hit the jaw or pocket it. You are trying to follow forward a diamond and a half from the 6 to get to the 3-10. I think the 6 will bounce out at least a diamond. You also have to worry about leaving a cut on the 13.
Good thought, Bob, on the travel on the 6 if playing the CB forward to the 3/10. It appears that if trying to play the 6 into the left inside of the pocket, the CB would not track properly for the safety sitting at the 3&10 - so - Final decisions would have to be made when able to be at the table.
I suspect it would be let the 6 play a touch right of the pocket and back up near the 2, in order to ensure the CB plays soft on the 3 and sits inside the 10 leaving no look at the 13.
