How to improve your game

mmm, you are playing chess since almost 2 months, isn't?, that's too little time. You will need consistent training trough years.

I learned to play when i was 8, but only played ocassionaly and not seriously. A couple of months ago i just started to really like chess, specially solving puzzles, and started to try to play more seriously. What i noticed, was that by training regularly, maybe playing some games and analysing my mistakes, and solving a couple of puzzles wich i did everyday because i liked it, i started to get a lot better. So much better in fact, that since a month or so i can defeat a friend of mine that was always better than me at chess. So, in my opinion you just need to be consistent, and regularly solve puzzles for example, everyday, maybe just spend 15 minutes or 30 minutes, but in time you will see your improvement, like with every other activity, not only chess. You cannot cram 2 years of training in 2 months by spending 10 hours a day (just an example), i don't think it works that way. But of course playing more time will probably give a more rapid improvement.

@karlgoethebier books and strategy are of little use when you keep blundering pieces. I'd say that playing tactics is a good place to start, and move a little slower.

According to Nakamura, Chess is 99% tactic below 2300. After 2300 it is 50% tactic, and 50% of strategy, endgame, etc.
Fide 2300 is a bit stronger than here, so Fide 2300 is lichess ~2500.

But i think, for players on rating 1300-1500 most tactic will be too hard.
80% of games loses because of simple blunders.
("Opponent attacked my piece, but i missed that". Or, "i went to some place and didnt see that is under control of Bishop")

Some soviet coaches (Chekhov Valery, Victor Komlyakov for example), advised to spend some time to training pieces capture and i think so too.
So my advice - master captures at first.
After u will see all captures instantly, its time to improve your tactic and upgrade it on automatical vision level too.

Now i'm a candidate for the next auto-da-fé, right?

#14,
I heard some cases, when GMs coach newbies and started with mastering rook vs queen endgame(no pawns), spending tons of hours.
They deserved auto-da-fé, but not you:)

Lichess has a great feature for the analysis of each game. Click on any game you have played and you will see a link for Analysis board. Click on that and then you can Request Computer Analysis. This will tell you all mistakes you made and what would have been the best move. See if that helps. Good luck.
