This is an interesting wwyd to me due to the options.
13 ball.
Offense ....banking to make, I am going into the 3 because I don't think I can get the 13 to the hole and hold the CB for a shot on the 3. The 3 should end up somewhere between the side pocket and the 1st diamond below. If you come off the left side of the 3 you should have a nice bank on the 1.
The downside is two fold imo. First is you could leave a cross bank on the 3 that will most likely lose the game. Second, the upside is limited to a couple balls.
Defense...2 rail the 13 to near the side pocket trying not to tie up your banking lane. Use stun follow to leave no bank on 11 or 3. Opponent response will most likely cross the 13 and put you in upper left, possibly behind the 13. From there it looks like it will turn to a up table game.
12 ball/straight back. Banking this ball straight back, not to make but to leave close, with inside holding the CB behind the 9 or 5 is great shot if you are confident that you can execute. The dangers here are obvious. That said, if you can execute your opponent will be in a very difficult position.
3 ball. Moving the 3 ball to your side around the 2nd diamond and leaving Cb behind the 11. The danger here is coming up short on the 11 and letting your opponent see the 3 ball or of course going too long and selling out the 11.
If executed correctly, the opponent will bank the 13 up his side and put the CB under the 3...balls start going up table.
My shot selection depends on how I am feeling and score in the set.
