Why I get crushed by 1500 and 1600 in Bullet?

Whenever I play with 1500s or 1600s rating players in Bullet, I get crushed by them easily, but I easily beat 1750+ above players in the quick pairings. Are 1600s more powerful than 1700s? Then how do they stuck at 1600 and not reach 1700 above?

Infact today only, I defeated two 1750+ but lost to two 1600 :(

Yes, it is because the 1500-1600's play less predictable moves, that trows you off your game!
Learn to deal with those moves.

That's not the matter see @AnonymousChessKing one player rozikul 1653 u lost see his highest ratings it was 1882 I guess u played on lobby where a 1200 player can play like 1600 as everyone and anyone can play with them
