TIL: Finesse faults in Tetris (revised)

For posterity, you can read the original here:

As a somewhat novice Tetris player, I've always wondered what Finesse was, but was too scared to ask what it meant.

My first encounter with the word "finesse" was on popular fast-paced multiplayer block stacker Tetr.io. In tetr.io, there are multiple single-player modes, these include:

• A time-attack mode called 40 Lines where you clear 40 lines as fast as possible (creative name, i know)
• A 2 minute score-attack mode called "Blitz"
• "Zen", which is a endless mode where several practice options are exposed, such as adding rising "garbage", changing the gravity, or resetting the board without having restart your session
• And a "Custom" option to "freely" make your own wacky modes or practising in non-standard board sizes, like 4-wide.

Before starting 40-Line mode, the player is presented with a few practice options. One of these options is called "Alert on finesse fault".

So, what is finesse then?

Finesse is a word that refers to the "skilful handling of a situation", or a "refinement or delicacy of workmanship, structure, or texture". (Merriam-Webster, n.d.)

In the context of Tetris, however, it refers to a technical jargon "Two-Step Finesse", which is "an input optimization technique" where you save key presses by taking advantage of DAS or Delayed-Auto-Shift and the rule-set's rotation system. ("Finesse", 2019)

It's critical for players who want to go faster to learn and understand two-step finesse because it allows experienced players in multiplayer scenarios to place pieces faster, allowing them to get garbage out faster, or in time-sensitive contexts, such as getting a faster 40L time or higher blitz score.

Ok, how do I learn finesse?

You... don't.

Well, you could by watching orz's video on finesse, I am not your boss after all.

However, to learn how to finesse you don't necessarily need to explicitly practice it.

Finesse can come naturally just by playing multiplayer tetris, since you need to keep clearing t-spins or tetrises/all-clears in order to stay alive for much longer, and to do that, you need to place pieces faster and more efficiently.

Personally, I do not enjoy the standard ruleset or tetr.io's modified version of the ruleset, however understanding about finesse and what it meant has helped me be more mindful about where I place the pieces on the play field while going as fast as I possibly can with my current knowledge.

Thanks for reading!
