How much does your strenght drop while playing blindfold?

Say I am 1800 elo. How much would my strenght drop if I played blindfold.... maybe by 300-400 ELO ? Also how is it possible to play multiple boards blindfolded?

You'll be lucky to beat a kid. I think it warrants a new account, specifically for it.

I think Kolty got better!

Play one blindfold game then get back to us.

If George "Kolty" was alive we could ask him his opinion @Puzzleandlearning Koltanowski ... when he was over 80 years young in 1984 at the National Open in Las Vegas he did his Famous Knights Tour Blindfolded with name & numbers on the board !! ... Calling out Texas to 08824 to Maine to whereever around the board the Knight jumped without touching the same square twice'

Google George "Kolty" Kotanowski Wiki @Puzzleandlearning

i'm currently rated 1250 on my blindfold account.

hello i'm a kid and i could beat you

@whitehathacker thanks sport, when you reach my rating you might be able to prove it

ah but you have a lower score in classical and a higger in bullet so you would probably go really fast in the classical game and lose to some tactic
