So I mostly play Puyo Puyo Tetris and occasionally TGM series. I'm overall a pretty decent Tetris player (Can play relatively fast, 40 Line PB is 1:21) but I'm having trouble improving. I mostly play battle mode and aware that T-spin clears are VERY important. I know HOW to do a T-spin but I do not know the key openers and when I should set-up a T-spin midgame as well as any T-spin combo set-ups. Whenever I play a match VS a Japanese player, I often try to set-up T-spin but frequently just set up Tetris since the opponent has already built a solid 5-6 puyo chain or Tetris player has a T-spin combo set. Another reason is when I set up a T-spin, I occasionally just get this big hole and keep on building the left and right sides of the screen. I guess what I'm asking is what are the main T-spin openers, set-ups, and combos to learn and when I should use them as well as how I should practice them. Also, any general advice that you think may help with these issues would be greatly appreciated. Apparently, the RNG in Puyo Puyo Tetris and modern Tetris games in general are pretty predictable but I don't know how it works. If someone could explain how the piece generator works, that would be very helpful too. Many thanks and I appreciate your help!
