Jude i would have to disagree
Things to consider. How good you play, and is the shot one that you have in your arsenal and how good do you play safe.
If you lock them up behind the great wall of china, most experienced players are not going to try and get lucky by trying to hit the 1 and hope to get a roll.
Unless you freeze them to a ball, or they are extremely wet behind the ears, most people, seeing as the 3 is no prize, are going to knock the 9 out of the way if they can, or if they can't, the 2. They would still have a reasonable chance to return to the table because the runout isn't naturally there.
I am assuming that the 1 ball would be uptable and that being the case, should you knock the 9 away, someone cannot fire in the 1 and break up the 3-4 and still guarantee their shape on the 2. and i highly doubt they are gonna try and break up the 3-4 from the 2's position unless they are high or unless it is do or die.
If the 2 is moved, the runout is still a coin toss unless they happen to move it right by the tied up balls.
Seeing how the 9 is making the pocket huge, and it's not a super severe angle, plus knowing that i can make the shot a high % of the time, i would opt for cutting the 9 down the rail and getting 4 rail shape on the 2.
If i hit it good, the win is automatic.
If i hit it poorly, the pocket is still huge enough that i will still make the ball with sideboards, and have a shot on the 2 and then i can rethink my options at that time.
The difference being, If you play a safe from your position, and play it poorly, or leave them a window, you run the risk of selling out a shot with the 2-9 still hanging there for the easy win.
After a shot on the 1 that hits the 9 away, you will be playing a safety on either the 2 or 3
without an easy combo there to haunt you should you hit it so bad as to sell out a shot
For people that play very well, but don't play high end pool, they should STILL go for the shot.
The margin for error is huge, and if they happen to hit it so bad that it hits the outside of the 9, it still knocks it away, and whoever is at the table still has to deal with the 3-4 unless they are extremely unlucky and the 1 double kisses the 9, and the 9 stays exactly where it is, with the 1 hanging in front of a hole with easy shape on the 2.
If they can't even hit the outside of the 1, they might even still hit the 2 for all we know, and still have some outs unless the 1 replaces the 2 and makes it easier, but they would be extremely unfortunate if that were to happen. Odds are totally against it.
For people that play high end pool, I see a lot of good things happening from going for it.
Sure i see the bad as i mentioned, but i feel that the good/lucky FAR outweigh the bad/unlucky possibilities of this scenario when shooting it down the rail.
Plus, if you happen to connect on this shot, and make it clean, your opponent is going to want to hang themselves.
It would do a lot psychologically for yourself, and against your opponent if you rifled it in.
I am a firm believe in something i heard on an accustats tape a long time ago. That in the game of 9 ball, while you might be able to safe your way to some wins every now and then, your gonna have better success if you shoot your way to them.
