Yes it does have the potential of opening two or three open balls instead of one on his side. Could be a fair trade with the 7/3 opening up.I don't like your shot because it opens up too many balls on the opponents side of the table and doesn't present a threat to him in the process. Actually the only shot I like from the shots that have been discussed is Strouds shot, but even his shot could end up costing him if he allows his opponent to shoot off the left side of the 4ball and send the spotted ball toward his pocket and at the same time rolling the cue ball behind the 6ball.
If i'm in this spot i'm doing something simple and effective, in terms of getting back to the table to make something happen. My shot would be to simply roll off the 4ball to end up in back of the 14ball near the side rail. From there my opponent cannot do anything to put me in trouble and the next time I come back to the table I will be in a better position then i'm in now.
You described a good shot provided there are no return options with the 7 ball -- doesn't look like there would be.
