Unless you have a trust fund, the main limitation is simply that you don't have the time to study that young folks do. Yes most top players started very young and there are studies that show the advantage of doing so, but I don't think you have super GM as a goal. No reason you can't get good enough to play in tournaments, but don't underestimate the work involved. You've already fallen into a beginner trap, thinking that sheer repetition of tactic training will lead to major improvement. No, you have to study as well. It's gonna be pretty hard for you to figure out puzzles unless you know what to look for.
Luckily for you though, there are a whole bunch of tactics courses in the Chess Mentor that address specific tactical themes. GM Patrick Wolff systematically covers all the motifs in 15 or 20 courses. Highly recommended. Danny Rensch has videos that cover the same ground, but of course tactics are just one phase of the game. Take a good long look at the Study Plans that chess.com provides to get an idea of just how much you need to know and start studying. Best of luck and welcome to the Game!
So I'm at a bit of a loss of what to do right now and maybe need some direction.
Im 27 yrs old and have only JUST NOW started to play chess a month or 2 ago. I originally started learning so that I could play with my boyfriend when he said he liked to play. Now 2 months later I find myself really drawn into the whole thing. The strategies, the studying, the analyzing etc. Im constantly on the tactics app for chess.com and trying to push myself further and further in score. Im sitting at 700+ but I keep wanting to pick my phone up thinking, "Ok! I can push it to 800 today, I know I can!" Im playing against 1000 computers right now and recording my games and analyzing them afterwards to see where all my screw ups are (there's a lot of them!)
I know the ultimate goal is to just have fun and enjoy what Im doing but I also have an extremely competitive side that keeps telling myself to push further and further. I guess my question is- Is it plausible to train myself for tournament play? Should I bother? I see all these 1400~2000 players boasting of playing chess from a VERY early age and here I am 27 and only JUST learned more than how the pieces moved a month ago.
I mean, what are the limitations here for someone starting so late?
