He's playing the shot at a gentle pace without allowing for the throw of the cue ball. As he explains with the blacks he played into the corner pockets, the cue ball throws off line, comes back onto the line in an arc before striking the object ball.
I totally understand what he is trying to do, and i understand that the cue ball will swerve and arc and eventuall come back on the line of aim.
what i have trouble with i think he is explaining it opposite to what is happening. even if you look at his hand gestures when he explains how the white will arc, with right hand side he says it will arc from right to left. i thought its the other way, from left to right.
surely when you put right hand side the cueball squirts to the left first then will arc back, providing there is space to do so.
look at the shots from the blue spot as i explained in my earlier post, he was aiming right but the OB goes left, it should be the other way because the cueball will go left and hit the OB on the left from his position.
