If you get 4 wided you're screwed
GOtta 4 wide back
Unless you're just way faster and better than them 🤔

In modern guideline Tetris, IMO if you don't know how to 4w or haven't bothered learning it, then that's your problem.

Captivate


4-Wide, fourwide, or 4w, is a stacking method where you leave 4 columns open with 3 residual blocks (marked sky-blue above) on those columns. If you stack this way, clearing one line with a mino will again leave 3 residual blocks. Your primary goal is to chain these line clears to do a high number of combos.


Attacking this way is so efficient that 4-Wide became infamous for being broken. In current guideline Tetris clients, starting from combo 9, each single line clear sends 4 lines and more on later combos. This is 2 times more efficient compared to a T-Spin Double, which sends 4 lines with a double line clear, and 4 times more efficient than a Tetris, which sends the same amount of garbage while clearing 4 times the amount of lines. 12 to 13 combos is almost always enough to beat any opponent.


One of the very few downsides of 4-Wide is that misdrops are usually fatal.

Center 4-Wide


Having the 4 columns open on the center is relatively harder to build compared to just having open columns on the side, but it helps you avoid being topped out by spikes. Since the game has an invisible buffer above the playfield, you also perserve your stack on both sides. This means that you can accept a large amount of garbage while also retaining your combo potential.

It is extremely hard to beat an opponent using Center 4-Wide when you have equal stacking speed as your opponent in official clients.

Opening Bag

On stacking your opening bag when you have a SZ and TS/TZ start, respectively. The right side is built like the third picture.

Subsequent Bags

The easy way is to repeat LOJ on one side and to repeat ISZT on the other.


Obviously, doing this won't be possible for every sequence, so you'll need to learn some other ways to stack these sides. Go to Tetris.wiki's 4-Wide construction patterns to see some alternate patterns you can use. Practicing sprints with 6-3 stacking is a good way to naturally learn these patterns.

Generally, creating these kinds of surfaces give you a higher chance of continuing your 4-Wide stacking:


Creating a flat surface and doing this isn't good.

Side 4-Wide


Can be used as a way to play against Center 4-Wide, but it won't beat Center 4-Wide. Stacking Side 4-Wide can be easier than stacking Center 4-Wide, but unlike Center 4-Wide, you are susceptible to being spiked.

Opening


Just put an I over there and start stacking up. Using a T or a Z are other options.

Building Side 4-Wide is also possible after certain openers. Using it as a followup after an opening DT Cannon would be a popular example.


Mid-Game

Side 4-Wide can also be used as a mid-game technique. This is not as good as an opening 4-Wide as you can only do a limited number of combos and also due to the fact that you are susceptible to being spiked while building it. Therefore mid-game Side 4-Wides are generally accepted as a legitimate strategy.

People usually spot these residuals mid-game and stack up on the side.
