Bank the 2 into the 4. Use the 4 as somewhat of a blocker for it to leave it on the long rail, somewhere close to where to 4 is already. Shoot the CB with as much right hand side as you can, and use the spin to create the cue balls speed. Go short, long, opposite long rail with the white. The key would be to get the white on the long rail and the 9 block the 2. If it pays off it is hard to get safe for the opponent if they're kicking at it.
My other option would be to go short rail first with a touch of right side to flick the 2 maybe a diamond further away from the corner pocket and the white up to the other short rail. Need to make sure you contact the short rail with the white, even if the white bounces out a diamond there is still a lot of distance and gets your opponent thinking. They have full view of the 2 in this shot, so depending on the creativity and execution skills of the guy your playing you might end up in a worse situation. Also, I'm not sure if the point is in the way of this shot so it may not be on.
Option 1 is an attacking safety option, and therefore has more risk. Option 2 is easy to execute but is more of a passive defensive safety. Depends on the player but I'm fairly attacking minded....not enough so to warrant kicking at the 2, but enough so to choose this shot.
I would also contemplate really tying up the 4 and give up ball in hand. Roll it upto the 9. Can't get to the 9/4 from where the 3 is easily...thats a tough break out. Forces them to go into the cluster from the 2 which could make the player snooker them selves on the 3. They would have to hit the shot really well to develop the 4 and get on the 3. Against a pro I wouldn't contemplate this, but in a league match it becomes a contender for my.choice of shot.
