If my opponent is a great banker then choosing to pocket the 14 is a harder option, for they will bank the 11 and your right back in the same scenario with either the 11 in the pocket or pocketed.
But, if they are not known for strong banking then the option to pocket the 14 is very viable, and by leaving the cb frozen on the end rail close to their pocket they now have to back bank the 11 which has a built in cross corner cb scratch. So a little reverse or inside english is needed to protect against the scratch, and there is also a consideration of not leaving a return shot on the 1. All this makes it harder for a not so strong banker!
I agree with Billy that taking the 1 over the 11 is the better option for burying the ball in the pocket, but I also recognize that the end game favors taking the 11 for it is harder to get shape on the 1 or to bank it, as Billy points out. But, also if the 1 is moved it opens up the 10 for a double out of the corner bank for the opponent. This is the key shot for it is the game winning bank for the opponent, and has to be protected against.
So the bottom line I am taking the 11 if I am playing a great banker, but if they are not a strong banker I am pocketing the 14.
But if I am shooting the 11 it is with "no" english, jacking up can throw off the shot! Whitey
