Okay, so this is more for me than anything (I tend to be able to call upon information better when I've written it down, so why not here), but just some basic info about pressuring with Noob and how I like to go about it.
Obviously you'll have to mix these up, be as random as possible but still remain safe.
b+1 - Great for closing distance when pressuring for a +3 on hit and neutral on block. When I'm pressuring I typically follow this up with an upknee which connects on block, whiffs on hit unfortunately :\ I'll typically use b+1 after a f+3,3xxupknee on block or 1+2 because it puts you perfect distance to connect with this move and compensates for its slow start up.
b+1,2,1 - Decent to mix up after you've poked with b+1 a few times since they may not be expecting it. ALWAYS follow this with upknee as it connects on either hit or block. Be careful when using this combo, you can only hit confirm the third hit, and recovery on b+1,2 is dreadful if blocked so use this sparingly as a cross up attempt will hurt a lot.
1 - Fantastic pressure tool, comes out quickly. I typically follow with upknee which connects on hit or block.
1,2 - Great pressure tool, closes distance well and has great pushback on block. Following this with upknee is totally dependent on the situation. Since you'll be neutral on block regardless I suggest only following with upknee if you connect your first hit. Because it ends the string before the upknee they can block and give you a +4 advantage again.
f+4 - Personally, I love this move for pressure. After a blocked 1,2 or f+3,3xxupknee it can totally catch an opponent off guard since most people aren't used to seeing it too often and it has very solid range on it. Always follow with an upknee which connects on hit or block. I don't recommend following up with the second hit (3) ever considering they can simply duck it and get a full punish.
f+3,3 - My personal favorite tool. I'll typically follow this with an upknee 90% of the time, but every so often I'll cut it off there to continue pressure. If you do happen to catch an opponent with this in the corner and follow with upknee you can pick them up with d+1xxupknee for a 35% combo.
f+3,3,3 - Another incredible pressure combo. You can hit confirm the third hit so my strategy is usually: If they block the first hit, upknee after second, if you catch them with the first hit follow with 3,3xxfront portal. After I immediately dash back putting the portal slightly in front of me. This cuts potential counter pressure and gives you a safe place to begin zoning. This puts good distance between your opponent and yourself so use that to your advantage. The one time I use a different strategy is against Raiden, in which case don't dash backwards after the portal so if they teleport they'll land right on it.
Hope this was useful to someone out there. Keep up that Noob pressure!
EDIT: Honorable mention: b+2 seems like it has great potential giving +5 advantage on hit, unfortunately I haven't been able to work this into my routine. If anyone finds a solid way to pressure with this I'd love to hear it!
