Does this Double-Triple setup have a name?

[dragontamer]

I was watching some PPT play, and the Tetris player did the following. I don't think I've ever seen this before.

The double-triples on the wiki are:

I can't say I know all of the forms on the wiki, but neither of these describe this particular method.

Here's the "still frame" before the Double

This is a BT cannon invented by @26_nameless on twitter that is becoming popular on PPT. It goes into C-spin (TKI in Japanese) and has a chance of perfect clearing cleanly with 5 bags. This means you can loop it if you get lucky. It also has a very high chance of perfect clearing if you dip into the 6th bag with hold. Some people call it BTTKI perfect clear. It's good on slow paced games like PPT. I don't know if it's okay to post the setups, but @26_nameless has a bunch of example fumen and videos if you click on his liked tweets.

Just to link that one video that went a little viral:

3-mins Ultra (7 x BT -> TD -> PC)

It's sped up by 50% (still much faster than I can play) but the consistency with how he can loop the setup is purely amazing. Infinite TST is way more effective on Ultra though. Not sure if this setup is that good for multiplayer either.

Incredible. This is a 5-bag "playing forever" loop.

I tried to accomplish something similar for Infinite TST but was unsuccessful (the setup uses 4 S pieces 6 L pieces, 4 J pieces, and 6 T pieces, instead of 5, 5, 5, and 5. There are parity issues that I have worked out but haven't fumened up yet).

Its an opening threat, but if the opponent hasn't been KO'd by the first perfect clear, they would have sent garbage to you before the 2nd perfect clear. Case in point: A "4-wide" player only needs to send 1-line of garbage (or any odd-number really) to permanently make perfect clears impossible.

With some careful garbage timing, you probably can make it to the first perfect clear without taking a hit. TSD / TST / TST / TSD offers a lot of "protection". You just gotta sync your TSD with the opponent's TSD and/or Tetris. But if the opponent goes TKI or something quicker, you probably are going to take damage and therefore be unable to perform even the first perfect clear.

It still a TSD / TST / TST / TSD loop, but any good multiplayer game requires downstacking into garbage. A "Garbage tetris" is not only 4-damage sent to the opponent, but it also cancels out 4-lines for an effective differential of 8-differential between the two players.

--------

EDIT: As an opening: its 4 TSpins in 5-bags. That's quite good, especially given its reliability. Even without the perfect clear, it seems like a solid start to a match. I have a feeling that maybe center 4w performs well against the opening, because the first TSpins are about as slow as a DT Cannon (11-damage by the 3rd bag). The perfect clear likely comes too late, and the 4w player would be executing their combo by then.

TKI and other quicker TSD give a little bit more damage in the early game (14-damage in 3 bags), although bag 4 and 5 are weaker.

[Okey_Dokey]

Just wanted to mention the similarities between DT Cannon and BT Cannon. Both setups result in a T-Spin Double into T-Spin Triple. DT Cannon has the advantage that it can be stacked for more initial bags and needs less time for softdrops. BT Cannon works for less bags but also for most SZ starts (Pseudo-DT Cannon works for SZ starts but it wastes more time on softdrop).

DT Cannon can be also expanded to sidestacked 4-wide or Infinite TST (for Ultra use only). Both setups can be expanded to Triple Double Attack (C-Spin) to get rid of the TST overhang. Thereby, BT Cannon seems to give more opportunities to end in a Perfect Clear afterwards.

For example, the BT cannon PC setup with the highest success rate would look as follows if translated to DT Cannon. If I am not mistaken, then there's no way to stack that setup. It offers more opportunites for a PC then the stack in the Fumen above (one additional opportunity is shown).
