This is a build INnoVation used in his WESG 2018 qualifier.
The build starts with a fake proxy and transition into a two base. You make a timing attack with Marine, Tank, and Banshee.

The timing to move out is when you have three Tanks.
The build uses a fake proxy build, which is one of the more common proxy options in patch 4.7.1, and it takes two early Refinery. This essentially is a quick tech to Factory then expand build. The fake proxy creates information gap in Protoss' decision making.
Many Terran use Banshee and Siege Tank to fill the transition gap to build up their mid game army of bio and Medivac. Hence, Protoss may not realise Terran want to do a timing attack. This could end the game quickly, as demonstrated by INnoVation.
