Does anyone else besides me jab to downsmash to jab to downsmash and repeat?
(shielding opponent):
(midrange)slap>dsmash (to push away)>(now spaced)slap>dtilt>sliding dsmash>slap>backwards stutter-stepped fsmash~
I ended up writing a lot of stuff about spacing and counters. It just looked like too much to take in at once. The above string actually works by stringing 3 things I do (and you should too!)
1) Slap>DSmash: pushes people away after a somewhat poorly spaced slap. eats shields with a possibility to shieldpoke
2) Slap>DTilt(>Sliding DSmash): spaced slap to DTilt is deliciously safe on block, being both spaced, and manipulating the crouching lean away>lean forward property of her DTilt to protect you from most counterattacks (people with disjointed hitboxes notwithstanding.) Sliding DSmash punishes shieldrollers who think they're punishing you, while generally remaining very safe if you dont make a hit.
3) Slap>Stutter-Stepped FSmash: spaced slap (after everything, have we met?) keeps on the pressure, then moving(dashing) back a hair while FSmashing makes a large gap between you and your enemy without any extra lag. Peach then leans back in (having avoided a silly fast jab or shieldgrab attempt, and pops them with the racket/club(pan should miss, unfortunately.) If they stayed in their shield, you smack that, too.
The whole string works if they remain in their shield or try to shieldgrab (Perfect Shielding ruins this, like anything else in this game.) Otherwise you should stop where they try to escape and regroup (preferably with a turnip in hand.) Olimar should be able to run a pikmin out to get you (his grab) when you attack high, though. And anyone with fast, ranged aerial attacks can anticipate the first DTilt or DSmash and aim for your head for a hit (in which case you have the option to SSFSmash THAT counter, its all about who thinks furthest ahead.)
I guess if they anticipate your next attack, they have a chance at hitting you--but that is always true. If you dont like the entire string, they work individually very well, and 2+3 is stronger than 1+2+3. Most likely though, you'll score a hit (which would be your opening to follow-up) or they'll roll away (free hits on shield? awesome.) If they roll, and you're not stuck in your next attack, chase with the dash attack (she gets a nice boost to cover the spacing you made.)
I'm afraid I'll detail an entire 3stock match if I continue, so I'll end it here~ (I cant wait for the week when we do slaps (*'-'))
