Early pressure, don't allow them to stack their 4 wide enough for it to be a big threat.
I think tspins should do it, but you have to be consistent and not break b2b bonus.
I think it takes 7 tetriminos to make 4 combo, 14 tetriminos to make 8 combo and so on ...
You get a t tetrimino every 7 tetriminos or so, so you should be able to do t-spin doubles.
Low tpm differential case:
First 7 blocks:
combo potential added = 4, lines sent by spinner = 4, remaining height in 4wide matrix = 12
Next 7 blocks
combo potential added = 4, lines sent by spinner = 5, remaining height in 4 wide matrix = 3
only 2 of the remaining rows can be filled by 4wider
At this point, 4wider will probably start combo. Combo potential from built up 4wide should be about 8-11 (depending on where garbage hole is for 4wider)
Lines sent from 8-11 combo is 13-25 I believe. But it also takes 8 tetriminos to do 8 combo, which allows for another t-spin sending 6 lines. By the end of this, you will be somewhere in the top half of the matrix with easy to downstack garbage (becase garbage hole changes less for higher combos).
Thats a hypothetical scenario and assumes E+ settings. but i hope u see that its possible to survive 4wide. Some mitigating factors: 4widers confidence and DAS level, the t-spin setup u use (t-spin triples and doubles), whether its a centre or a side 4w, 4w style (3x starting minos in gap vs hole-less start).
