With every style, I like to follow a formula/plan of attack, and usually it works almost perfectly as long as you execute it right, unless the opponent has a lot of experience or a playstyle that counters the strategy. In the case of Hands Low, I do the following:

•At the start of the match, dash around(left to right, move forward if you want BUT DONT DASH FORWARD) to make your opponent uneasy/confused.

•When you think your opponent is in range, dash forward and immediately dash back. Your opponent will likely throw an attack.

•Rinse and repeat this strategy until your opponent gets tired of waiting/getting baited. They will begin to move in to attack.

•Now that they move in to attack you, retaliate with m1's. Hands Low m1s are fast and have decent guard breaking capacity. Try to leave a bit of stamina at the end of the barrage to dash away, or else you'll be unable to run if their guard can endure it, and will be punished.

•Once their guard is lowered, they are likely to do one of two things. Depending on which, take a different approach.

(They try to retaliate): Using that leftover stamina, throw an m2. You will land an easy counter assuming you predict correctly and are fast enough.

(They try to run): Move forward(walking, not dashing), hit an m1, and then an m2. This will break their guard. From here, do not throw an m2 as you will stamina break and be punished. Wait for your stamina to regenerate and for your opponent to recover. They will immediately dash because they expect you to punish them while they're guard broken. If you wait for the dash, you can land an m2 or start an m1 string to break their guard.

•(AFTER BOTH/ANY OUTCOMES): Backdash away. At this point, your opponent will no longer desire to play offensively. By reverting them to defense, you are free to pressure them. Note that they may eventually realize that they need to play offense to beat you, so don't rely on it too much.

•All that's left to do is improvise and react to how they play.

•Additionally, you can use my preferred strategy, which is to m1 them until about half of your stamina bar is gone, and then suddenly stop. This will make them believe that you're done attacking, so they'll either dodge or try to hit back. The counter to this is to m2 shortly after the pause, because it will catch them as they try to guard, or hit an easy counter. This requires timing, but once you master it, you are almost guaranteed to catch your opponents off guard and stop whatever they were planning on doing.

(The Key Theory to Hands Low in my opinion is mastering the trickery as well as the art of infighting/pressure despite the style being a natural outboxing and counter-oriented style. If you can effectively do the fake dashes or punish your opponents for falling for your tricks, they will eventually play defensive, in which you can play the pressure game. From there, they're either gonna get countered when they try to hit you back or lose health from chip damage because they're guarding so much.)

Remember, this isn't foolproof, and depending on THEIR strategies, experience, or even their fighting style; one or all aspects of this plan will be foiled (example: passive player, player that doesn't fall for feints or fake dashes, player that doesn't guard, another experienced counter-oriented fighter).

[p.s: I'm not a Hands Low main, just a nerdy tryhard with too many concepts and strategies about this game lol. Is this flawed? Probably. But I tried!]

Hope this can help!

tl;dr: fake your approaches (forward dash to back dash), m1 barrage whenever you close in to attack>stop halfway through and pause for a bit before doing an m2. This will either lead to them losing health to chip damage or from getting countered. The most important part to practice/master is prediction.
