After looking at some of your games, i see the usual:
Hanging pieces.
Not following opening principles.
Not double checking your moves.
Missing simple tactics.
What i would suggest is this:
Play slower time controls, at lats G30 and longer.
Lay off the blitz/bullet, if youre serious about improving.
Keep on studying tactics.
My tactics rating is currently 1450, and my training rating is 1500, yet I seem to be stuck below 1000 in blitz and below 1100 in rapid. Can anyone offer some advice on converting prowess in tactics to improvements in my game? I already watch professional chess frequently, read chess books, and solve puzzles daily, but I just can't seem to improve.
