unfortunately, footsies isn’t something that you can learn easily since there are so many matchups and variations. also, it’s hard to realize what you don’t know, so many of it depends on thinking outside the game to ‘figure it out’. here are some expansions on basics for ryu mirror
c.forward beats walking forward
c.rh beats whiffed c.forward
walking forward beats waiting to c.rh a whiffed c.forward
and then if you wanna take it a bit further, fireball beats all three, jumpins beat fireball, focus beats fireball, f+fierce beats focus, c.forward cancelled into fireball/srk beats focus and then you are back to c.rh beating a whiffed c.forward.
hahaha, and we haven’t even gotten around talking about f+mp, ex moves, dashes, hurricane kicks, and 91914 other things that can happen in a match.
it’s not easy, but keep practicing and do a lot of homework OUTSIDE the game.
once you got execution down, spending an hour THINKING about the game will help you more than playing an hour worth of matches/training mode.
