This is called BORING.
Seriously though, turtling/keepaway is good… but you have to be consistent. What are you hitting with? s.RHs, DPs, Sweeps… you’re going to need to land quite a few to win. So Be consistent. You’re giving your opponent all day to land the one opportunity he needs to kill you.
On the other hand… If you get in their face, go for crossup, go for meaty, blah blah you can wipe them out instantly. Round over in 10 seconds. It’s something to think about… you gotta be buff though, and be able to carry yourself without getting killed.
Keepaway = FEAR/Not Dying
Rushdown = COURAGE/Killing the opponent
Against some characters… getting close is being brave, but also incredibly risky/stupid. Gief, Honda, etc.
Try doing HK at VERY LAST SECOND… against meaty fast FB.
Another thing against DJ is to STAND (not duck) just outside of sweep range. DJ’s love doing sweep… when it whiffs, sweep him back.
Also, always try to DP the 2nd kick of the dread kick.
EDIT: Oh yeah… do you know the ghetto cornertrap??
Basically, knock them down in the corner (DP/Throw/whatever)… then position yourself at one of the “markers” (rock on the ground, whatever). It’s a little more than half screen.
Lay down meaty Jab FB. When they block it, immediately throw another one *, then another *, then another *, whaddya know another *, etc… if they jump, * = jab DP. Then start again.
Once they KNOW this is coming, they will do different stuf to get out, then you can mix it up… If they block a deep jab FB, throw quick fast one to hit them as they jump straight up… or hesitate and wait for the straight jump and then smack 'em with a FB before they land. They get knocked down, you start again.
If they have a projectile, fast FBs help here too… after blocking a FB, if you think they will try to match it with their own (Guile/DJ), throw a fast one and he should catch it in the face.
Basically though, once you get this pattern going… they will try to get out of it by jumping straight up or with specials and stuff. If you can anticipate these options, you can counter them, and start again… DJ in particular has a hard time with this trap.
