I agree with Bakkd, this part of forum isnt receving the necessary attention that should has. But write about a matchup isnt easy at all.
I wrote something nice about the Guy match in other post so I will repost here, perhaps there is a lot more to talk about it.
Guy pressure can be infinite but it is not safe. I fight against a lot of good Guy`s and one of my best friends is one of them. Firstable you got to know what kind of pressure the Guy player use more often:
If he use elbow drop pressure you got to choose Ultra 2 to scary him, but there are other ways to stop that:
1-You can time your Oil Slides to beat the Elbow Drop or escape the pressure or corner, if you dominate that you wont have problems with that anymore.
2-You can use Stand HP as anti air but that recquire a lot of precision cause Guy can cancel his flip in elbow drop.
3-You can Duck under with Forward MP or Forward Dash and SPD him, but that one is really hard to do.
4-Only defend is a good choice too.^^
5- Using FADNC is nice but he can grab you with the flip so dont use that a lot.
And there is a tip against this kind of pressure: Do NOT stay Stand if he is close to you in the flip move cause he can grab you so stay crouched.
There is the Run Stop pressure, that is the kind offensive that good Guy players use cause they can frame trap you with Crouch HP,MP and Stand MP and they can overhead or Slide FADC.
The best way to stop that is wait the Run Stop and immediately punish him with Crouch LP into LP Oil Slide, but if you think that you got enough reaction use SPD. Yes you can Punish that shit.^^
And you can stop his overhead move with Crouch jab too. ^^
Footsies: With oil Guy cant handle your footsies , cause you can use FADNC in his best pokes, just dont get to predictable with focus cause Hozanto got armor break properties and some of them are safe on block unless you use Ultra 1, but it is pretty hard to punish on reaction.
Unoiled: Guy can use his normal Slide and that is a terrific poke if used correctly but you can beat that with Stand HP, but pay attention cause Guy got other nice tools such as his Stand MK and MP that got a pretty good startup and priority.
Guy Wakeup: You can safe jump him after a Oil Slide walk a little bit back and Jump forward with HK.
DDT setups are nice too just dont abuse cause Guy got a nice backdash so they usually use.
Safe Slide are good too, cause after they defend you can baited him or go for SPD or if you fell confident use Ultra 2 cause will catch his backdash , Jumps and his best Reversals.
Use meaty moves are always a good option to vary your offensive and go for a more safest option.
Mix up all that and they are in trouble.
Your Wakeup: Take care with his frame traps cause they are dangerous. BackDash is a nice option even if you you are unoiled. Pay attention with Forward Jump Medium Kick Crossup this can be really dangerous when they mixed up with Elbow Drop but Ultra 2 can handle that. Back-DNC is always good, nobody expect that and a lot of people do not even understand what happen.^^
Other tips: You can punish Guy overheads and normal slide when defended with Oiled SPD . Normal Slide made in max Range is almost unpunishble, my friend dominate that ~~. Normal slide used really close can be punished with Light version normals.
Pay attention in what the Guy player do after a defended Hozanto to counter his next move.
Guy does have some kind of DDT Setup , but there are few setups. Be aware.
Guy can jump in the wall so Ultra2 can be baited in the corner, pay attention.
I would be really grateful if other players add more stuff to his matchup. And please if I wrote something wrong correct me immediately.
