There are 3 important aspects that can change the game online vs. your experience in singleplayer modes:
- Your opponent: he's going to learn your fighting style and punish your repetitiveness. He can use mind tricks, and usually DOESN'T want to lose. He can and will spam and use "cheap" tactics.
What you can do about it:
It's hard to change your fighting style with characters like Noob or Smoke, but it's essential if you want to win.
With experience, you'll learn to "force" an opponent into teleporting or doing a special move to render them vulnerable on block.
Mixup slow ground recovers with wakeup attacks. Make sure you've got at least 1 juggle combo and 1 High+Low hits combo that you master and can use at will. This is the difference between life and death most of the time online.
- Lag: it's the only aspect you have no control over. One second it's there, the other it's gone. It ****s your timings up (all the precious hours practicing) and makes you miss combos and some attacks look like they should hit, but miss.
What you can do about it:
Even if lag slightly changes during the course of a match, it usually stays within the same range so you must adjust to that as quickly as possible. You usually get a good idea of how important it is during the character selection screen. If it's too bad, just quit the session. If lag don't seem so bad, what I usually do is I keep it very defensive until the opponent makes a mistake then I try my favorite juggle combo. During that small window I usually got a good idea of how much slower my moves need to be from now on.
- Yourself: some people aren't affected much by the events during a match, some are competitive and get nervous. I fall in category #2. I want to win and I analyse everything during a match.
What you can do about it:
If you feel nervous because you lost 30% of your health in the first 15 seconds of a fight, don't panic. You should be able to do the same damage back if you know a combo that does. If you see you'll most likely lose the first round, do not break a combo or use your x-ray. (like you got 20% or less health left, and he still got 80% and up) Preserve your meter and round 2 will just be like a new round 1. Knowing that you got a full meter is a psychological advantage too. A good opponent will always be careful and will fear an x-ray and play it less aggressively. If you see the opponent is much better than you and you just can't do anything, just block and watch him play... see what he does to get to you. Learn. Attack when he takes chances, but other than that, just try to survive defensively so that you can learn as much as possible from him. Beware of grabs if you constantly block. Unless you played like more than 100 matches online and know 75% of all characters basics, expect to lose often. It's part of learning. You just can't expect to own everyone if you only know 1 character very well.
You will win over noobs, but people that main another character will destroy you if you don't know the basics about that character.
Don't be afraid to use the hidden character selection icon... some people will look at the character you pick and choose a good counter character.
Hope this helps a bit.
