@Darth:
I'm sorry but… no. I might be biased, because I've read a lot of Sun Tzu when I was a little, but... no. Trying to call that a strategy hurts me.
Sabo's strategy might not have been what I might describe as "masterful", but he implemented many of the things Sun Tzu discussed. For example:
@Sun:
All warfare is based on deception.
Hence, when able to attack, we must seem unable; when using our forces, we must seem inactive; when we are near, we must make the enemy believe we are far away; when far away, we must make him believe we are near.
Hold out baits to entice the enemy. Feign disorder, and crush him.
If he is secure at all points, be prepared for him. If he is in superior strength, evade him.
If your opponent is of choleric temper, seek to irritate him. Pretend to be weak, that he may grow arrogant.
Sabo first tried to simply grab the fruit. When that didn't work, he baited Jesus by clashing with him (destroying his arm guard). Then he feigned disorder by doing nothing but dodging Jesus' attacks, and made it appear he was unable to attack, using Jesus' attacks to weaken the Colosseum. This also kept Diamante off him (since it looked like he had his hands full, and Diamante is a showman, he focused on Rebecca and Bartolomeo instead of going after Sabo) - taking advantage of the arrogance of both Jesus and Diamante. Then, when he felt things were ready, he suddenly busted out a move to finish off the ring itself (again, misdirection, since everyone would have expected him to attack his foes, not the ring itself). Or, as Sun Tzu wrote:
Attack him where he is unprepared, appear where you are not expected.
It's also reminiscent of when Sun Tzu wrote:
Thus the highest form of generalship is to balk the enemy's plans; the next best is to prevent the junction of the enemy's forces; the next in order is to attack the enemy's army in the field; and the worst policy of all is to besiege walled cities.
Rather than confront Jesus head-on (akin to besieging a walled city); or go after the fruit again, which might cause Diamante to also target him (a junction of the enemy forces); he balked the enemies' plans by keeping them off-balance (while making them think they had him off-balance) and targeting the ring itself.
Sun Tzu also wrote:
Therefore the skillful leader subdues the enemy's troops without any fighting; he captures their cities without laying siege to them; he overthrows their kingdom without lengthy operations in the field.
Which is, yet again, a fair description of how he handled the competition.
Yet another thing Sun Tzu wrote was:
If equally matched, we can offer battle; if slightly inferior in numbers, we can avoid the enemy; if quite unequal in every way, we can flee from him.
Sabo used deception to give the impression that he was inferior (or even quite unequal) to Jesus.
One final quote from The Art of War which applies:
What the ancients called a clever fighter is one who not only wins, but excels in winning with ease.
Hence his victories bring him neither reputation for wisdom nor credit for courage.
He wins his battles by making no mistakes. Making no mistakes is what establishes the certainty of victory, for it means conquering an enemy that is already defeated.
Hence the skillful fighter puts himself into a position which makes defeat impossible, and does not miss the moment for defeating the enemy.
