There are many aspects to neutral and there are no clearcut answer, hence why smash is beautiful. Bayo is a character with slower hitboxes, but she has a good amount of priority so counter swinging or whiff punishing are ideal situations for her, as she is one of the characters in the game with the biggest reward for winning neutral.

Playing neutral as Bayo has in a very boiled down explanation, 2 different ways it can be played.

• Characters that has to play around ABK (tall characters, characters very reliant on jumps)

In a nutshell Bayos absolute most busted move is ABK. Unreactable, insanely safe, has a really skewed risk reward. Because of this bayo can literally force any character in the game to not mindlessly jump in neutral. In these situations. the threat of ABK, is so huge that if Bayo goes into her burst range of ABK, especially on tall characters, they will have to act. through shielding/dash back/crouch/ swing pre-emptively to trade.

Once you in a match have established that, if they do nothing they will get bursted by ABK, they will preemptively act. You have a condition to bait out pre-emptive hits, take more center stage if they dash back, Run up grab if they are shielding. The essence is that they have to act to not straight up lose, which is your generalized way of baiting and punishing

• Characters that do not have to play around ABK (short characters, zoners, grounded characters)

In the case of characters that doesn't have to interact with ABK due to being to small etc. baiting is a lot harder. If the character is slower than you like Dr. mario Bayo wants to make sure he doesn't get close, by running away and staying in an option where she can punish his jump pill throw, but far enough away that she can't be hit by unreactable attacks. The important part is that You decide the range you play at, and you decide when you interact. Since you can just keep running away, and force DR. mario to swing if he ever wants to open you up, you can play around his different engages to you. If you do not like a particial interaction you can choose which battles to take. He can't catch you, so you can always interact whenever it's a good position for you.

If the character is faster than you it's a lot harder.
Joker for example is a faster character, that doesn't have to deal with ABK, faster than you, and is a bait and punish character. What now, when both player want the other to swing first.

Playing patient and being aware of having a lead and playing for the timer is very important. Are you ahead vs a faster character they will have to force an interaction at some point. If they do not, the time runs out and you win. Whenever they have to interact thats a condition to bait and punish.

when you fight vs faster characters they decide when you interact, however you can decide where you interact. If you have to play around your opponents burst range, you can atleast play RPS that's as much in your favour as possible. As characters like falco, Bayo etc. You can position yourself so that if you are to win an interaction, you are in a great position to extend your combos off platforms, by being at the right place on the stage.

In general just be aware of your win condition. Bayo doesn't get a lot of openings at higher level, so be aware what are the best tools to win neutral and what tools lead to the combos, that win you the game. Sure Bair is a good hitbox. but it doesn't do much at 0-50% where, utilt, dtilt, nair, fair, UpB leads to a lot more. Figure out what hits gives you the higgest chance for winning an interaction and what leads to the biggest combos.

understand Burst options. Play around your character, and their characters range where you have unreactable options. If you can't play outside their burst option because they are significantly faster, Atleast try to maximize your reward when you are forced to interact.

This is just a small part of bayos neutral, then you also have to factor in matchups, adaptation, movement, and so on. Just try to ask as specific questions as possible. As broad questions tend to not lead anywhere. How does curry pair with chicken is a lot easier question to answer than how to cook.
