You and I have discussed this, Bob, and we're on the same page, but on this forum, I'll never endorse a "try this in case your opponent is clueless" approach when that approach may come with a cost. If it's cost free, fine, but even then, a plan for how to handle it if opponent doesn't do something silly must be in place before a shot is selected.
In this layout, against a strong player, the immediate choice is probably between risking the kick in of the fifteen or taking three. If you've already decided on taking three, tapping up to the six costs nothing, and maybe once in a while opponent will do something ridiculous, but if you're OK with trying to kick in the fifteen, you shouldn't afford a tactically sound opponent a chance to make you shoot it from frozen to the six, so you should consider shooting it now.
If the declining handful of confirmed old schoolers on this planet, like you and me, who know all the 14.1 defensive tactical theory because we were around the pro scene during the straight pool era, are to be of value to those who ask what the right defensive tactics are, we need to explain what the best options are against players who know what they're doing. If we don't, we forego an opportunity to ever so slightly restore straight pool defensive science to where it was in the golden age.
By 2000, it was already true that few of the top players knew most of the defensive tactics, but today, almost nobody knows them. Nothing has accelerated the death of superior tactical play more than the emphasis on exhibition runs over tournament play, and there's great reason to believe that, in the short-term, the trend will continue. Tournament straight pool in America is very close to dead, and the relative absence of defensive threads on AZB continues to evidence that all most players care about is high runs.
