I don't think you are going to want to take a foul lagging up to the 2 or 13 balls.. soft kicking the 4 ball is ok I guess.Bill,
To answer your question, It doesn't. If the cue ball were further from the side rail I would be more in favor of it, but I see this shot as in need of excellent control of both speed and direction, and unless some right english is used, which I don't advocate, some power must be applied because of the fairly full hit.
Hit this shot too hard or too soft, and a sell out of a good bank on the four will result. With so many loose balls around my opponent's pocket, don't want to encourage him to take even an off angle bank at that four ball.
My choice would then be to either kick at the four ball or take a foul lagging the cue toward the thirteen and two balls. From there I should be in a better position to help my cause because the foot rail will become a safe haven for me until I can do something to equalize the table somewhat.
have a nice day
