TvT: 1-1-1 Banshee Expand

Let's face it, 1-1-1 is a very common build, especially in TvT. This is a variant I use every Terran from SlayerS_Ryung to ZeNEX_Byun (see what I did there?). With good reason, it's a solid build that has few holes in it with a lot of advantages. On bigger maps I'd argue the gas first build is better, so knowing that version is also great if you play T. However, you don't get out the tech too much faster so, meh; it feels much safer having more Marines in the beginning.

EXECUTION: This is a standard opener and you'll do all the normal things you'd do. You have to bungle it up pretty bad to auto-die in the early-mid game. Your first 4/5 Marines should be making their way towards the enemy base, clearing any watchtowers along the way, once your first Helion starts making. The idea here is to scout the front and possibly kill some marines. If they have a bunker, just back off (duh). Best case scenario, they were a bit too greedy and you end up killing a lot of marines. Either way, you're just thinning the marine numbers. If they went Marauders, run back to your base and build a bunker, then proceed to win or get way ahead with the incoming Banshee. Just make sure you watch and micro your Banshee(s). They not only serve to harass, but scout as well. If you suicide your Banshee into marines, you will hence be known as TheBestfOu.

IN GENERAL: Your first Banshee will scout and pressure your opponent while you expand and macro up back home. Unless the enemy got a really fast Viking or Stim, your Banshee will do damage. Depending on the situation, you may want to get another Banshee. For example if you spot an FE, with two Banshees you can harass BOTH of the other T's bases. If you spot he's going Banshees, get a Viking or a Raven! I don't usually opt to get cloak, it's a big investment and the Tanks Siege Mode comes out so much later that if he holds well and counter-attacks you might die.
