If you think opening knowledge is the only thing stopping you from beating a GM, you could easily beat any lower-rated Club player even a piece down. Your online rating is such that you would play people far worse than low-rated Club. The worst thing that those missing 'rarer sidelines' could POSSIBLY cost you is being down a whole piece.Ergo, if your knowledge of chess *removing the opening (and move-order) completely from the equation* was even Expert level - again, you claim it to be GM level- you'd easily be 1600 rated in Online Chess.
I am 1700+ on ChessCube. That's where I play chess.
My all time high is 1825, but I have beat 2000+ and 2200+ rated players.
And it's well-known that chesscube ratings aren't inflated the slightest.
If I played on chesscube I might be higher rated then carlsen if Yereslov is 1825 there!!
Have you been on the site?
I have played on both Chess.com and Chesscube.
The rating difference is only very slight.
I don't agree with their entire gambling system, but they do have a nice interface.
Do a test then, and then come back with the results.
yereslov i challenge you to a live game!!!
You would probably play the Bongcloud and easily get crushed.
...or most likely, both.
For the sake of science, I created tonight an account on chesscube, under the name Irontiger_che (Irontiger was already registered but it is not me).
After 20 games (16W / 3L / 1D), I reached a 1871 rating, which is about as high as I ever got on chess.com. Add to this the fact that I am tired, not used to the interface (I got two of my losses immediately after subscribing), I expect to reach a safe 2000 if I continue, which is a difference of rating of 250 points.
So much for the "slight" difference in ratings.
You like to fit in.
It depends on the players. Some 1800's play very well.
And some play like crap. Avoid the blitz players.
By playing chess, probably?
Your analysis snippet is plain ridiculous.
9...b5? allows the natural 10.e5, when Black stands as good as lost.
You are funny.
Damn, you got there first.
