can 900 rated solve this ?

I doubt any FM can solve this

I solved all of them, but a 900 ratedd apparently done it better than me, so I was wondering if it's even possible

Impossible!

this is the 900, he solved 6 other puzzles in addition to this

First puzzle: very standard theme

second puzzle: there’s only one move that can realistically work it’s just a matter of seeing why

third puzzle: again not very difficult because it’s quickly clear that the moves Qxh2 Nxg2 or Rxf2 are not working so it’s then just a matter of spotting the idea

fourth puzzle was a little bit more unusual geometry but again you’re very limited in what you can actually consider as black is threatening moves such as …Qe1+ spoiling the party.

So in summary it’s hard to conclude if a 900 can or cannot solve these but I do know a couple of VERY weak players (under 1000) that solve puzzles pretty well but who never get any sort of decent rating because when they play they can’t stop blundering. So it depends on the individual imo.

thank you sir

What's the answer to the 4th puzzle ?

Qc3+, took me like 20 minutes

I took a poop before I found the solution

Bruh it's so obvious i should be ashamed. I'm sure it didn't take you 20 minutes. Thanks for the details.

see that's my point, if you can't find the solution, how can a 900 elo find the answer better than me

It's possible. Depends on time too. And the CM said everything, some players are able to find brilliant moves but blunder a lot.

that's crazy to think about

not a 900 atleast but a 1800 like me can maybe solve all of it cuz i did

Yes But maybe a 900 can solved the all puzzle but in 10 minutes
