You must to be able to hit the the shot every way known to mankind and back again.
Draw light or extreme power, any amount of English, lay it up, 1 rail, 2 rails, 3 rails, less or more english. etc.
The King of strokes for this shot is digging under the cueball and dropping in on the opposite side
of the short rail, that's your true tester, if you can stroke that you can draw stroke all other options blindfolded.
This is a stroke drill worked in 4 increments and distance from short to 3/4 length table.
Whatever is easy, how I, or anyone would play it, is irrelevant.
You must have the ability to send your cueball anywhere when called upon.
You must have complete Stroke Control and technique.
When you own the strokes there are no questions, only choices, because you are capable
of doing anything you want with the cue ball.
You only get one chance at a shot.
I've never heard an opponent say,,,, Hey buddy you dogged that stroke
set it up and try it again.
