Which "minimum of quality" are we talking about,
@Sarg0n ?
Ok, your opponents sometimes blunder on move 10-15, especially if they are 200 points lower rated than you are.
You can then feel haughty, that they failed to take the necessary time.
At the same time, you will sometimes blunder on move 50, perhaps even in a good position..
.. but rather than going "Ok, my time management was shit", you'll STILL feel haughty - that they merely flagged you, weren't better at all, and it was immoral. Or something.
lichess.org/h8OAoRP2/black/In this game, you manage to get 9(!) Blunders. All of them happen from move 38 onwards. Is this the minimum of quality?
Both of you make an array of laughable mistakes in this ending, because neither of you has the time to appreciate what's going on, and you just kinda have to make moves.
What if you had played faster in the Opening/Middlegame? Perhaps you would have blundered on move 15, and gotten laughed out of the room. Perhaps you would have 3:30 on the clock by move 40 (rather than 1:30), and could just smoothly outplay your opponent in the Rook endgame. Would that be less "quality"?
With 30s on the clock, you'll play 68..b2, and go home the winner. You had 10s left instead, misplayed, and then even proceeded to flag.
If you save yourself those 20 seconds, by making moves quickly earlier in the game, sometimes you'll blunder in the opening. It happens. But perhaps your move 50+ will be less of an RNG mess then, and you actually get to calculate in an endgame.
The only thing that is able to tell which approach of the two is actually superior, is RATING. The better approach will win the majority of time, simple as that.
2200-2300 Lichess Blitz is astonishingly low for a 2200 FIDE (dnno if that's your current rating, but CM implies you at least had it once), which heavily implies that your current approach is rather awful.
Blundering on move 50 isn't any "better" than doing so on move 15 (usually it's far worse, as you will be unable to bring the game back at that point); you should aim to minimize blunders as a whole.
As written in the classic 'Chess for Tigers' - if you don't lose as many games to playing too fast (ie blundering early), as you do to playing too slow (ie blundering in time trouble), you need to play faster.
Being proud of "outplaying" an opponent while investing 2-3x their time/move, and then "just" getting flagged / blundering in the endgame.. will get you nowhere. Try to play the early part of the game quicker, to improve :)
P.S. It's hilarious to me, how someone that hates timescrambles appears to exclusively play 5+0, rather than 3+2. Absolutely senseless.
