I've shot this one like this several times
A simple pattern
won my last 3c match with it recently
and you can play it 4 rails like i drew, or 3rails with more angle and hit the red from the front
But with 4 rails like shown you have the chance to push the white close to the corner and the red away from the rail a bit making position for a 5-7 railers around the table for the next shot, possibly
Larry; if, i needed 1 point, I may play this shot, but, not as exactly diagrammed. The 2nd ball (white) can not be positioned as diagrammed. The Ob has to be contacted 1/2 or more full to get the CB to side rail, and go 5 cushions. The 2nd ball will travel much further than you diagrammed.
