TY recently has been using a TvZ build that resembles the characteristics of early three Command Centre and 2-1-1. The build is unorthodox but well thought out.
The "3CC" suggests it takes an early third Command Centre, and the "2-1-1" implies a set of buildings that leads to a timing with Stim and Medivac.

This build is a modification of the classic early 3CC 3-1-0 build popularised by INnoVation. The original 3-1-0 put down two more Barracks then a Starport after the third Command Centre, and you move out with Stim and 2x Medivac (usually line up with +1/+1). TY's build still goes for an early third Command Centre and moves out with Stim and 2x Medivac. However, the timing of the third Command Centre is pushed back slightly, and your move out timing is much earlier (but with fewer units). Instead of putting down the third Command Centre while the Factory is building, you put down the second Barracks first. Then, when you have 400 mineral, you put down the third Command Centre like other early 3CC builds. The second Barracks ensure you've the minimum production power to produce sufficient number of Marines to line up with Stim upgrade early on. This is pretty much tested and refined with the once popular 2-1-1 build in TvZ. Otherwise, early Stim is an inefficient investment when you don't have the production power to ensure you've at least close to two Medivacs of Marines to make use of it at the time the research is done.
One of the key strengths of this build is in fact its slight modification to the 3-1-0 timing. The Stim and Medivac timing of 3-1-0 hits after 6:00. There is a sense of security from Zerg's perspective when Terran go early 3CC, as there is no real dangerous attack from Terran. TY's build hits a Stim and Medivac timing (with four Hellions) at around 5:30~5:45, and this unorthodox timing catches Zerg players off guard.
