The rarest achievement in chess.com!?

what abt the the achievement for winning with only 0.1 seconds left?
everyone who plays bullet pr blitz gets this

Congrats

Some achievements are really easy, but I think checkmate with all the pieces on the board is the hardest

I have it too, but it is mostly luck
The one for 10,000 puzzles would take forever (I dont have that one)

yh frfr but its not hard its js time consuming

According to me, the one that is hard is get is the discovery checkmate with king or checkmate by castling

My records show that this was awarded on 11 February 2018. I think the awards were new then. I'm certain I've done this dozens of times as I've played substantially more than 100,000 blitz and bullet games, although only 70,000 on chessdotcom.
