I have a friend who plays Cammy and beats me using consistently using only two buttons. I have been using mainly O. Sagat against him, but have tried the whole cast.
His gameplan is to land a knockdown. He does it by either walk-up sweep, cannon drilling under my high tigers, or jump roundhouse my lows. Every now and then i'll guess right and land a tiger shot, but he usually gets in without taking a hit (if i do hit him with a standing fierce or roundhouse it tends to trade. tiger uppercut seems to ALWAYS trade, though i know the damage is in my favor.)
After he gets his knockdown, he does safe jump strong, into throw.
This jumping strong is the death of me. It stuffs my tiger uppercuts even on reversal. I've only been able to beat it with jab shoryuken and short flash kick because of the invincibility. So, I'm forced to block. After the block, he goes for the throw.
I can either attempt the reversal or counter throw. The counter throw seems to work at random, but its usually in his favor. The reversal works if it comes out, but we all know its tricky to get a move to come out on the exact reversal frame. So, most of the time he gets the throw, and before you know it he's back in the air again with the j. Strong. Being O. Sagat, I can't tech the throw. He doesn't even know how to holligan throw. He just uses Strong and Roundhouse to win.
The only luck I've had is with O. Ken (j. DP EVERYTHING he does), T. Hawk (360 the tick) and Guile (flash kick the tick). However, I'd really like to learn this matchup with O. Sagat especially with it being one of his easiest fights. I feel bad that I only occasionally win and that's usually if he whiffs a cannon spike or some other dumb mistake.
Also, whats my best move with O. Sagat when a opponent is fighting close range? Standing short into tiger to push them out?
