There is very little wiggle room in the shot. You have to play the hit on the red to move spot to the right place and if that is not the right fullness to bring red off the rail only as far as indicated, it is difficult to adjust. Can you take ball in hand and find the place you need to be? If you can play half-masses, there is a lot more wiggle room.
I've played it many times today
I had no success with the position in the second image
When I did have success was when I brought the cue ball down more level to the red, little to no angle and some reverse English,
Even then it's tough,
Need a super fine little hit one the red to just bounce it off the rail, to have a full enough hit on the white
And the few times that I did it successful,
I didn't have the perfect position to continue, always too far ahead of the white with my qball
ITS HARD!!!
Also I don't have a decent cue atm
It's like a 40 inch player's cue with about a 12.5mm pool type taper and a funky screwed up Elk master tip
So can't do much any fancy cueing right now
