I struggle with this one in particular, a close friend of mine plays R.O.B. and wins maybe 2 out of 3 matches.
It's not like he's walking all over me, and I hope I've gotten a little better since I last played him, but my main concern is that I can never force him to approach. The guy camps just as well as I do, and if I start moving in I'll try to PS the dual projectiles and either get caught in a dash grab when I'm shielding, secure another safe position on-stage, or even his own f-tilt that's actually pretty good at spacing, I don't know if it outranges the first hit of our f-tilt. One solution seems to be to actually PS the projectiles successfully, which'll take a little practice and anticipation.
The other tricky part of the matchup is his laser on my grenades, which is often the reason I end up approaching in the first place.
One great thing I learned from this thread is to try and f-tilt the top, and throw it up to prevent reuse, I'll definitely try that.
However, what is CQC (I read it in the first post)? By blindspot, is that R.O.B.'s backside? And if I'm recovering from up high, is it possible to fast fall air-dodge through his n-air?
