Openings
With an I tetromino early in the first bag, you can try a TKI opening.

TKI 3 TSD Opening With TST finisher
 Variations 

Try one of these when the O piece comes late in the first bag.

 TSD-Imperial Cross 

 TSD-Super TSD 

 TSS-TST-TSD 

 TSD-TST-TSS 

T-Spin Double Replacements
T-Spin Triple

Imperial Cross

 TSD-Super TSD 

With no T in sight, save the TSD setup for later and use an overhang to get the T down in the hole, leaving a Super TSD setup behind.

TSS-TST-TSD

You might try replacing the TSD with a TSS, leaving a TST-TSD setup behind. Sending a small amount of garbage at first may tempt the other player to overstack, leaving them vulnerable to a large attack.

You can use a T, and slide it under the over hang and rotate;

..OOGGGGGG ...IGGGGGG JJTIGGGGGG JTTIGGGGGG J.TIGGGGGG

That will make a TSD, and make a slot for another.

Effectively making a TSD B2B and allowing you to continue the B2B chain with a Tetris.
