Can you win against a higher rated player in blitz 😎😎

Yes

I have and will again.

Yes I beat Some 700+ ELO-Rated Players in Blitz

Yes it is possible even I had won many times

yes, you can overcome your opponent

Statistically, everyone can, just less than 50% of the time.

pawn one move, without thinking second pawn one move (look out for enemies knights and bishops), third pawn, fourth pawn (set the icons for tenth of a second), knights out...

If your opponent does no pressure, you will do. If you are white your pawns and knights are an Avalanche. If you are black, you are the Vesuv. (One Minute :-)

An Avalanche is a rapid flow of pawns out of the sky down to the other players lines.

Your pawns are snowflakes, covering the earth beneath. (one minute)
