I like a shot here that may seem some what haphazard but it's actually a well planned out option. However, the cue ball needs to be 1-1/2" or more off the top rail for me to feel comfortable with the execution of the shot, allow me to explain. I like shooting the 1ball into the rail to clip the 12ball on the outside of the ball and draw the cue ball back toward the top rail. Lets examine the many different results with this option.
#1. You can hit the shot perfectly and send the balls to your side of the table and the cue ball near the top rail. Excellent result.
#2. You can narrowly miss the 12ball with the 1ball and then the 1ball will possibly bank off the side rail then off the bottom rail back up table off the top rail then toward your pocket, leaving the cue ball near the top rail straight in on the 12ball for your opponent. Good result.
#3. You can shoot the 1ball into the 12ball hitting the 12ball thickly, and still get positive movement from both balls, drawing the cue ball near the top rail. more good things can happen for you then against you with this type of hit. Good result
#4. You can miss the 12ball and hit the bottom rail with the 1ball sending it into the back or side of the 10ball. I see some good things happening with this hit and some not so good things happening, however, as long as you draw the cue ball back toward the top rail your opponent will have to earn what he gets. Not terribly bad results.
The key to the shot is drawing the cue ball back to the top rail. You're close enough to the 1ball to hit it reasonably well, I like the gamble here.
I like this option a lot from this position, try it, I believe you'll like it as well.
