Today, we learned how to set up another Tetris opener, the Hachispin. The hachispin starts with a t-spin single and then can quickly transition into a t-spin triple. From there, it can transition into many different outcomes, all of which have their own viability and flexibility. It can also lead to a perfect clear with a fairly high chance, estimated to be around 70%. The hachispin is a great opener and also has two ways to play it out with.
The first variation is when you get an early O piece. Using the NEXT is among one of the more important things for Hachispin as it depends a lot on your piece order, unlike the DT-Cannon where ZJ and SL are interchangeable. Look for the first J or L piece. Whichever one comes first is going to be the direction that you take. If the J piece comes first, put the Z piece all the way on the left. Follow the image and try to build the formation.
After this, T-spin single into the slot that has been prepared. It is where the Z O and S are. You should get a formation looking like this.
After this, place either an S or Z piece to form the T shaped hole for the T-Spin Triple. Then, use either a J or L piece to form the overhang for the TST.
T-Spin Triple and then from there, you can build a Tetris well or just continue to clear lines.
