TKI 3 Opening

With an I tetromino early in the first bag, you can try a TKI opening, invented by Tetris DS player TKI. Given the right pieces, it allows for three T-Spin Doubles and a T-Spin Triple to finish. This is a good setup since it uses all pieces in a good balance, as well as not wasting your T.

Here is the basic TKI-3 Opener. Beneath are some variations on the setup. Throughout these, however, the basic setup remains the same.
