Puzzles are way different then actual games.
Getting 2550 is impressive, but how is it possible?
Chess is a combination of openings, strategy, plans, and of course, tactics.
In the puzzles, you just find tactics on a game, that may be in a 2550 game. However, just because you can find tactics like 2500s, does not mean you know the strategy, opening lines, and other things found in a chess game.
I hope this helps!
Guys… I recently got 2550 puzzle rating which is incredible to me because just 5 days ago I was at 1700. Is this progression good? Also I only have 900 rating in rapid, bullet, and blitz. How is this possible.
