1 Reaper FE into fast techlabbed starport to cloaked bancheese can really contain an opponent early on. You should be able to score some scv kills while your opponent can't march across the map early on with tanks/marines because you can cloak kill them. This means you can normally get your third pretty easy and just keep cranking out scv while you micro your bancheese.

In the end game, you probably still want to go tank/marines at least. But you can negate their medivacs if you get a 2nd starport with reactored vikings.

Flow normally goes like this: You get a bancheese in your opponents base, pop a few scv, dodge a few scans. Then they reactor out vikings and libs. So your own little tech labbed starport won't be able to keep up with their anti air production, but you'll have about 3 bancheese dodging scans and being annoying.

It is vitally important to get the 2nd or even third starport with reactors so you can then spend some time, and catch up on anti air. 1 tech labbed port and 1 reactored port will allow you to eventually out produce their 1 reactored port, but it takes significant time. IN the meanwhile, make sure you keep up on SCV production, make tanks out of at least one factory, and spam raxes after the third CC starts getting made.

The end game is always marine/tank. But you can probably negate some medivac cuteness by having air superiority.

This build has a sweet spot to get into position to starve your opponent as you start making vikings. The best way to win TVT in my book is to get some siege tanks in position, so they can't get to extra expansions. And the bancheese opener will give you great scouting in addition to containing your opponent, so you won't have to worry about being contained and losing yourself.
