Half-Step DT Cannon Midgame

[chopin]

Ok so here I'm making a small post about a very useful occurrence that comes up quite often in multiplayer games. I call this easy recognition method the Half-Step DT.

This is a common shape that arises on the field. By using the S/J or OZ as a hang, you can create a good shape with a good balance of pieces.

You can make it using other shapes too, but from experience, I find that these two work the best.
Half-Step A

Half-Step B

Notice that this shape is popular enough to have many possibilities:
Purple Rain - T-Spin Single, T-Spin Mini, T-Spin Double

TSD Stacking - T-Spin Double, T-Spin Double

In extreme cases or cases where two T's are coming one after the other, you don't want to waste either and wait for another. Here is a possibility that will either give you a TSS-TST-3 Combo or on games like NullpoMino, a TSS-JSM-TST-3 Combo all with back-to-back bonus:

Note that mid game Double Triple Cannons are extremely powerful and effective used mid-game. Sending 12-13(B2B) lines (TF) mid-game is better than even a mid-game Perfect Clear, and definitely more rewarding. Cheers

Nice, I hadn't thought of that before, I shall have to use it! You'll wanna amend your first fumen which goes into weird colours at the end!

Cool, thanks Paul. Fixed

I do this a lot mid game too, but why is it a 'half-dt" and not just a regular DT cannon?

[Magnanimous]

Cool, I hadn't thought of this.  Usually when I have a 2-7 split I just downstack normally...

[Paul676]

it's a half-step because the start is a half-step...

A quick note that the height of the overhang makes it easy to abort even after the overhang is in place, albeit a bit messy:

I'd hope you had two T pieces and an J piece somewhere soon.

When the DT cannon shape is detected by TF, it plays a noise from the TST that is a half-step below in pitch the normal noise for the TST. Duh.

its actually a full minor 3rd below

and when you do a back to back dt cannon then the tones play together in contrapuntal polyphony

Oh my apologies. I don't have relative pitch

Thank you, Chopin. Mid game patterns is the sort of thing really that is helpful to me in learning setups.
