Q is strong enough to where you can make it work, this game really only has 3 characters i'll tell anyone to avoid every learning. Q isn't one of them.
J.HP all day as your main jump in, J.MK and J.LP are also amazing air to airs for different situations.
Your goal is to get hard knockdowns or far away knockdowns so you can get your 3 taunts. If you want to have any chance get your 3 taunts in. Some matchups at the start of round 1 you BENEFIT from backdashing and just trying to get one or 2 taunts in. Like Chun, she's doing no damage to you in the first round, she doesn't have any meter, taunt and take the back fierce. Just be smart about it.
Good Pokes:
S.LK up close.
S.MK is amazing
C.MK is amazing
C.HK is good if you can get the whiff punish read.
All the other buttons are bad or have no uses, but you can get away with making it happen with these tools.
Jump back HP and neutral jump HP are also amazing tools.
Starting out Q players have a bunch of really awful bad habits that they choose to do for some reason, but I can't make any calls until I see you play.
Your mixup game is making them guess between mid with close S.MK and command grab, but honestly Q isn't about mixing up or anything like that. You play footsies, you whiff punish, you get taunts, and you wait for mistakes and capitalize on them.
Combos:
Close S.MK, LP/MP? Dash Punch, SA1/SA2
Command Grab, LP Dash Punch (hold), HP Dash Punch.
Command Grab, EX Dash Punch, S.HK or B.HK if you don't want a knockdown.
After SA2 if you ever choose to run that super against Akuma or Twins, you can do LP dash punch (hold) into HP Dash punch.
Ending a combo in SA1, HP Dash Punch and they're full screen away, and S.HK result in a free taunt.
Ending a combo in SA1 is a free 2 taunts if the opponent character doesn't have a method to attack you from mad far away.
Examples of who you SHOULDN'T try two taunts and why:
Chun with meter.
Dudley with meter.
Akuma with meter but honestly if you're 2-3 taunts in just take the SA1 shit won't do anything to you.
And you can probably just figure out the rest.
Thats basically it in a quick little write up, but yeah you gotta play really defensively and really smart to make it happen. Never force situations and wait for your opponents to hang themselves.
