[Star Wars] Is it true that Obi-Wan's "high ground" speech was more of a psychological mind-game rather than a tactical strategy?

In my opinion, Anakin did realize that he had other options other than foolishly jumping over Kenobi's head, and that he would have won the Mustafar duel if he had used them. However, by saying "I have the high ground" and "Don't try it", Obi-Wan was basically implying that Anakin wasn't powerful enough to make the jump.

Anakin, taking this as an insult to his ego, decided to ignore whatever strategy he had beforehand and make the foolish jump, for the sole immature purpose of proving Obi-Wan wrong. Had Obi-Wan just taken the high ground without saying anything, Anakin would still have his common sense relatively intact and would have done something else (such as jumping away from Obi-Wan and then running towards him instead of trying to jump over him).

TL;DR: The high ground wasn't effective as a tactical strategy, but IT WAS effective in playing to Anakin's ego. Anakin could have worked around Obi-Wan's high ground from a tactical/strategical standpoint, but because of his ego, he didn't "want" to. Anakin made the jump for the same reason someone would take a dare.

Obi Wan didn't *want* Anakin to attempt the jump, he genuinely was trying to dissuade Anakin from continuing the duel. If anything, it was probably more of a bluff than anything - hoping despite all evidence to the contrary that Anakin would consider backing down. 

But when Anakin jumped, obi didn't ignore the opening.
