Ok, this situation is obvious. Now, you can see the 1-ball so why push? A simple and effective safety is to cut the 1-ball toward the rail. Not only will you likely leave it safe behind the 5-ball but even if he can see it, where can he make it?
Sorry, I goofed on my WEI table. I was trying to illustrate a typical push situation and forgot to put a blocking ball in.
Now, let's assume that you just didn't bother to hide the cue-ball when you created this diagram. Then, you just leave that combo for your opponent and leave it long. Put the cue-ball on the head-rail and you'll minimize his options. If it's passed back to you, once again, you play the safety I just mentioned. From that distance, the safety probably won't be as good so you're in for a battle but a battle is really what you want. If you're lucky, he'll take an aggressive stab at that combo. If you're not, you may need to get tricky on him to regain control but it's well within reach.
You DO NOT set up that jump shot. That's just suicide. Getting over that 7-ball is going to require a jump-cue and a hard hit. There's no real offensive solution and defense is all but out of the question. Basically you just safed yourself.
