Yoshihiro SD is a T-Spin setup involving an EZ T-Spin Single that leads into a T-Spin Double.
[edit] General tips
- Timing - Practice making the T-spins with consecutive tetrominoes to send garbage in big clumps whenever possible. Try holding the first T tetromino in the hold box while you wait for the second. Then make both T-spins very quickly. This is good to keep in mind but can't always be done.
