Gouken isn’t bad he’s like sagat but without the scary ass anti-air options. Need a 3s mindset when jumping though. Respect the parry but unlike 3s … You can punish him for attempting it.
If he plays zoning gouken (the only type imo) I reccomend trying to build a bit of ultra meter before approaching him, really made me see the matchup a lot differently as his fireballs aren’t like Sagat’s as he doesn’t have a 2 hit fireball and his fireballs are slow. Approaching him with a half powered ultra without taking any real dmg isn’t good for gouken.
Fireball from 3/4th’s + of the screen or else eat a DP from him. Other option is fireball his fireball on reaction to build meter safely, if he tries to dp you’ll block in time.
Getting in is the tough part as his sonic boom like recovery makes it hard to get in. You need to learn how he’s going to anti-air you when you jump. He wants to use cr. FP as it’s his most reliable anti-air, but if jumped correctly you can beat it with j. FP or FK as it comes out kinda slow (if it does come out though your going to lose). If he gets stuffed he’ll probably attempt a counter or try a more situational anti-air like cr. MK or st. MK. These are kinda mind gamey as j. FP and FK can win based on spacing against the MK’s, and empty jump allows a good punish of the counter (i recommend land immediate dp cancel).
A way to get in besides that is EX Fireballs (if he ever EX fireballs do yours for a knockdown, his ex fireballs are terrible), right outside of where his fireball appears can be done on reaction to get a knockdown (and this is your ultimate goal as after a knockdown you own the match). FA’ing Fireballs you have to be careful as if you dash forward at certain ranges he can actually punish the dash with a sweep … ya i was very frustrated when i found that out. But if your closer you can FA it than dash forward dp cancel, sweep, or cr. MKxxfireball (ex if the cr. MK hits cuz you WANT a knockdown).
Really once you get a knockdown if you can corner gouken, the matchup is very in your favor. He’s forced to guess his way out of the corner, he can’t jump out as you have dp ultra waiting, he can’t poke you very well as cr. MK is his daddy. closeup pressure really his only anwser is guess counter which if done incorrectly means lots of dmg done to him and resetting him into the same scenario.’
If he demon flips just j. attack him in some way than since you recover first upon landing mix him up (if he parries you still recover first it’s funny i know).
Gen vs. Ryu
Learn to look for his jump … he wants to jump bad. However, Ryu’s FP shoryuken eats his jumps. Cr. Mk lets you ground zone him all day as his pokes suck. just frustrate him into jumping with safe hadoukens and cr. Mk and punish with shoryu ultra. Gen doesn’t have many good options against ryu just his jump is very very good and hard to reactively dp consistantly.
