I'm very happy to hear insight and interest in this thread!
I figured that the best way to start in the Art of Yomi is analyzing the ability to bait and observe your opponent. Sun Tzu believes that after your army is assembled (which I may discuss later, as it is a prologue to beginning your battle) that intelligence is the first step to success. Hence, deceiving your opponent to your actions is very important. Now before I start I want to explain that lets consider each match or set a "war", and each exchange a "battle". I'll also talk about the seperation of rounds and how strategy changes at each point in a round at a later date. For now, let's treat the time inbetween as a chance to regroup, reorganize, and change strategy.
Let's start off with the most basic quote which pertains to the topic...
-Hold out baits to entice the enemy. Feign disorder, and crush him.
I think "Feign disorder" is what a lot of new players misout on. Anyone can bait a reversal or a shield with a jumpin, but against experienced players it becomes more obvious when making an obvious bait. I think focusing on really not looking like you have any options (for example, running out of jumps, but still having an EX attack option, like F-Ciel's j.236C). Furthermore, we all know what our pressure is designed to bait or how to change it up, but do we really know what it feels like? Some people struggle watching their own play videos to find out, but if that's not important enough you could also dummy mode your own pressure to really see what it feels like to fight against "you". When you know what it feels like and when what options (like an H-moon shield bunker) feel good against your own pressure, than you can start baiting things from the first round in tournament.
-If he is secure at all points, be prepared for him. If he is superior in strength, evade him.
Whenever you fight an opponent that is equal or better to your own, one can expect to lose control of a battle. As LK says "It's not your turn.", so you shouldn't be rushing into a situation you cannot win. When fighting a superior opponent, try and convince them into using their better spacing and fundamental abilities and reduce situations to mere yomi. Jump with the intention to block. Maximize your character advantages. Try to create situations which make the flow into decision making. Try to utilize your opponents overconfidence. I believe Kusanagi did so well at Evo alone and compensated for his lack of matchup experience by forcing his opponent to make the best possibly decision they could make in a situation and being ready for it.
-If your opponent is of choleric temper, seek to irritate him. Pretend to be weak, that he may grow arrogant.
As I said above push your opponent into overconfidence in their position and ready your defenses. The closer one gets to victory (especially against a superior opponent), the more likely they are to take a risk to get the kill or abandon strategy for tunnel vision into success. Try to utilize any emotion you detect in your opponent, whether it be anger, fear, or ambition.
-Attack him where he is unprepared, appear where you are unexpected.
Most players understand their own weaknesses, thus they prepare for them and try to maintain a zone they have strength in. If your opponent gets too comfortable you can easily take advantage of their game. Sometimes teching out of a VSion EX ender or 5A'ing an approaching enemy can be a good move - just so your opponent keeps to their safer attack measures and experience. Once you move into that zone and prediction, you already have an advantage as you are limiting your opponents options into a more expected attack zone.
I honestly believe a heavy advantage in a war is the ability to observe and adapt quickly to your opponent. Whoever observes more of their enemy and attacks their strategy will undoubtedly win. If two players begin autopiloting, the person who notices the other's strategies will have an easier an quicker access to victory.
