How is this a 4000 elo puzzle?

Ts is not 4000 elo 🙏🙏😭😭

Call me Magnesium Carlsberg or Hikiru Nakamara the way I solved that puzzle.

But in all seriousness, is this some advanced trolling or did the difficulty loop on itself or somethin?

A puzzles rating is completely useless in terms of improving.

ok

some puzzle ratings are glitched for some topics like back rank and mate in 1 or 2 etc

Welcome to my world

lol fr tho its so easy

 :draw

SOOOOOO ez

where is the puzzle

This must be a mistake. This is more like 400 rated puzzle than 4000 rated. Essentially only one move that you could even consider and it is the right one :-)

Complete useless is kind of strong statement. There is moderate correlation between puzzle rating and chess.com rating, which at least strongly indicates doing one is likely to improve the other. So higher puzzle rating implies better tactical ability, but how well that translates to in-game performance is highly variable, but improving in puzzles is likely to improve your game as well at least to a point.
