My chess rating fluctuates between 1050-1150, but my puzzle rating is 1550 and growing. Is this discrepancy normal? Obviously my theory is poor and I don't study at all. I dont really have much of a clue in the openings and am really basic at the start. I am much better in mid to end games though. Often when I win its because I spot a tactic to gain a piece then trade down to an end game.
