Keep in mind this is for the WIN...Would you risk the cash on a 3 rail bank? I doubt it
Actually i set up your shot, 1st time i tried to bank 3 rail i made in opposite corner to try to keep cb on the rail, 2nd time it went in the side 3 rails, but cb went up table not safe had i missed it, tried it again i made it 2nd time, the 3rd i missed and left it by the side pocket cb next to it.
I made it two rails in corner pocket once, i tried the cut 3 times made it on 2nd, and 3rd attempt, the 1st attempt it hit the teddy of pocket and went to other corner pocket.
I tried several safe attempts, the most effective was to role cb very soft straight at the 8 and park cb on it.
After trying all above, i felt the above safe is most effective play, "you would live another day" as Grady Mathews used to say..God bless him.
