Is there room between the 7 and 8 to actually take the shot and make the 7?
Looks like it.
If you try to draw into the 7/8 and fail, you can leave yourself hooked on the 7.
If you try and draw into them and you hit it too good, you can bump the 8 and have the cue ball TOO close to the 7 and off angle somehow.
Personally, i'd just play position for where the cue ball is right now.
Then take an inside english shot on the 7 and come around for the 8 and you're home.
If you go too far with position on the 7 and don't have the angle to cut it in, you can always 3 rail the 7 so that it misses the 9 and hits before the side pocket and lock them up on the 8 and sending the 7 uptable, so that they can't jump it.
Just seems like a better % play with room for error then crashing into balls or trying to do trick shots.
If you play position for the bank on the 7, that means you are crashing into the 8 for position, and anything can happen at that point, both good and bad, and you basically have to get lucky to end up with a shot on the 8.
If you bank the 7 and hit the 8 full, you have good chances, but to do that, you have to draw off the 7 on the bank.
If you Roll the cue off the 7 bank, it might hit the rail, and graze the 8 as it comes off the rail, and unless you hit it hard enough to get it near the side pocket, the cue will hit the rail, come off the 8 and you will be perpendicular to the shot and have to shoot another bank or play safe anyway.
Plus, that 7 is just too damn close to the rail to bank it normally without having to stiff it with draw/inside english, HARD, and at that point, you are losing whitey anyway and hoping to get lucky if you manage to avoid the double kiss.
