Fox camping peach
There are many objectives you can choose for camping peach. Those objectives can either be:
- making her over-commit to something so that you can get a free punish
- to create an opening by assuming control of certain parts of the stage and forcing the opponent to come into said controlled spaces. Or to give you the positional advantage if the opponent chooses not to approach your space
- to rack on damage with less risk of getting hit (kind of boring though)
As I see it, peach has 4-5 options vs fox's camping. Which each option has a counter for. She can either:
1. Approach from the ground, and her main option out of that is to dash attack, since it's her only move that will reach quickly
2. Float at a height to try and cut off your jump towards a side platform. She'll probably try to f-air, but n-air is also an option in this case
3. They try to read a jump from the ground with a FH aerial, which she can fade away with. Either way, that one is the most risky option for her in the matchup
4. She doesn't fully commit to the approach and decides to WD back/DD to see if you'll attack her
5. She tries to approach you with a turnip, or tries some random gimmick. Probably the second most unsafe option
First step is to not go FD. What you need to do is shoot her with lasers to give peach the incentive to approach of course. The only time you should be lasering though is either when you are retreating, or when you are sure that you will be outside of peach's dash attack range after you land.
Taking control of center stage is where you are most powerful, since there is more space to DD, retreat away, or to the top platform (assuming you're not on stadium). Usually this will mean that peach is near one of the edges of the stage. This is where you want to laser a bit if she's not going to approach. If she takes a float height to go above the lasers, then you can either DD and wait for the whiff, or back off and move to the side platform to see if she will approach you. If she doesn't then wait for the float to run out and then come down and laser. If she does come, then move to the top platform and run around her, then go back to lasers. If you're absolutely Sure you can land a hit, then go for a b-air and see if you can land a combo. The main reason peach has problems in dealing with this is because, she is slow, doesn't have super long range, can't rise beyond a certain height quickly enough due to a crappy DJ, and doesn't have a fast move that arcs around her (well, f-tilt I guess, but that move has many problems of its own). Her u-air is a great move, but it can be spaced around pretty consistently. Same with her n-air (though that move is sooo gay).
Anyways, to my next point about her problems. With all these combined it kind of makes her have to initiate something, and/or anticipate where the fox is going to go. Even if she chooses to do nothing, she is a sitting duck when fox is above her on platforms. Usually peach would CC an attack from an opponent coming down on her, but then his drill breaks CC anyway and leads to a combo as we all know. If she wants to try to DJ and come up after you, or if she goes on one of the side platforms, you can go underneath her and take your positional advantage (u-tilt underneath, or b-air if you can intercept the aerial).
If you're at the side of the stage and trying to camp her, then as soon as she gets toward center stage (probably a bit further away on yoshi's), then jump to the platform that you are underneath and see what the peach does. If she threw a dash attack preemptively, that's a free hit for you. If you see her jump at you with an aerial, you can either try to move around it and b-air her, or shield it and then go for the punish. Alternatively, you can jump around her to the top platform and then move to the other side of the stage and camp again. At that point it's on you to decide when to attack her and when not to attack. Also watch for DD -> grab. It's pretty easy to tell when and where it's coming.
I know that I didn't mention anything about camping vs turnips. But that is because you be mowing down peach anytime she has one in her hand (maybe not vs a stitchface I guess).
Something else that people don't use in matchups: if you feel trapped by the edge, it's not a bad idea to grab the edge and do a ledge WD to attack an opponent that doesn't respect your space.
I feel like I'm missing some detail, but meh. I guess I'll add later when I remember.
Edit: man Jman was so good at camping peaches. It actually does take a bit of finesse
