1900 blitz here is not terrible. I've seen NM's here rated 1900-2000. Even seen a couple 1800's too. I'm starting to wonder if I'm capable of getting that high. I'd like to just to play a master once in a while but the 3/0 pool here is brutal. 1700 is about my max at the moment.
It's all a matter of what your strengths and weaknesses are. I am good at shorter time controls so when I was playing 3 0 I was easily 1700. Now I am playing 5|5 and now I'm 1550.
Not a matter of shorter time controls - A matter of increment blitz being more representative of your true ability (than non increment) and the best players online play w/ increment.
You need to be a good endgame player to play good increment chess. Besides, I don't understand the concept of time management in increment chess. Your opponent could have 2 seconds on the clock but if they are a pawn up, they could still manage to win.
Yep.
