Chess rating system

2400 is a bit low for a GM.

 Can you solve this puzzle? (It's kind of tricky, but you can do it if you try hard!)

Can't Black just promote the pawn to a queen, or did I miss something obvious...?

i agree

and in the end black can just take the queen

why would black promote to a knight

That was not a chess puzzle. Black can never have 11 pawns in a chess game.

hehe.

here go on too another forum topic id=f you want to talk about puzzles this is for chess rating

ratings mean nothing

I'm mostly amazed (or confused) by the number of rating systems.  I know the official one is USCF, but what I'm referring to is other websites I've visited.  One (unnamed site) in particular I played on awarded me 200 points for one game I won against a played rated 30 points higher than me.  Great for the ego, but not worth much in my opinion

USCF is only "official" in US. Other countries all have their own national rating systems. FIDE's world wide rating is the most officiel rating you can get.

The unnamed website which awarded you 200 points probably used the Glicko system, and gave you 200 points because you start with a high "ratings deviation" (RD) meaning that the rating value is very uncertain and will change very quickly. As you play more games, the RD value will decrease, and the rating value will change slower as a consequence.
