Quick question: How does everyone deal with an opponents mindgames? I've been having trouble with my friend's Captain Falcon. He dash dances a lot, and for whatever reason it fakes me out. I get baited dash attacking against his shield, which is frustrating because I should know better. I guess related to that, does anyone have advice for when you're playing someone and you can tell that they've "figured you out," so to speak? Having a variety of options is obviously important, but should you practice different things even if what you're already doing is working? Anyways, thanks in advance for any responses.
I tend to use their own medicine against them by also throwing in mindgames. Mix up your approaches, use Din's Fires for different methods (I feel this is one of the better mindgame options Zelda has), and recovering from different angles are ways to be less predictable. Farore's Wind also makes a good mind game once you master how to airdodge cancel it on the ground - landing in various spots and hitting your opponent with surprise attacks. It will be harder for them to read you using Zelda's limited but wide variety of options.
Zelda's dash attack is really good, but a mistake a lot of new Zelda players make is using it too frequently to the point they'll be shield grabbed a lot. SH Nayru's Love, dash grabbing (though not my favorite), and Fsmashing are mixups in addition to dash attacking. What I do is to look at my opponent's DI. If they're in the air right in front of me, I usually dash attack again because I know they won't be able to shield it. You'll have to use more vital judgment when they DI into the ground, even more if they're just standing there. 'What are they expecting for you to run into them with?' is what you want to ask yourself.
For your scenario, to avoid a Captain Falcon knee (or any aerial for that matter) out of a dash dance, you would need to learn how to really outspace this move. Zelda's pretty tall, so SHing or even FHing away doesn't do too much (plus C. Falcon's air mobility is superior to hers). Therefore, try wavedashing OoS in hopes you can escape the sweetspot and punish with a Bair or something. It's just how I handle my friend's Captain Falcon.
