1/1/1 in TvT is a different beast to 1/1/1 in TvP. You can still do some early banshee harass before your timing comes, and in fact, 1 banshee is really good with the push (if you have air control, one banshee can go to town on defensive tanks), but you need to be producing vikings for air control to get the full range of your sieged tanks.
Ohk fair enough but say if the oppenet was to do a tank marine build what should he do to counter that if that makes any sense
Just go watch that video and try and copy what demuslim does. It's a fairly safe, very solid way to play the matchup. He explains why he builds stuff in the order he does, and it all really makes a lot of sense.
But don't go over thinking and trying to do different things to 'counter' your opponent every game when your mechanics just aren't up to being able to macro effectively on the fly like that... This is one of the big mistakes I still always make... My opponent does crazy shit and I try to change my build to 'counter' them because i get thrown off, and wonder why i lost when im floating 3k minerals at 10 minutes.
