How to climb rating ladder (1100-1400) and become a solid chess player?

711 blitz games

153 bullet games

2 standard games

How do you expect to improve, when all your playing is fast time controls?

Try slower games instead of blitz

Opening Principles:
1. Control the center squares – d4-e4-d5-e5
2. Develop your minor pieces toward the center – piece activity is the key
3. Castle
4. Connect your rooks
Tactics…tactics…tactics…

Pre Move Checklist:
1. Make sure all your pieces are safe. 
2. Look for forcing move: Checks, captures, threats. You want to look at ALL forcing moves (even the bad ones) this will force you look at, and see the entire board. 
3. If there are no forcing moves, you then want to remove any of your opponent’s pieces from your side of the board. 
4. If your opponent doesn’t have any of his pieces on your side of the board, then you want to improve the position of your least active piece. 
5. After each move by your opponent, ask yourself: “What is my opponent trying to do?”

Middlegame Planning:
1. Expand your position:
a. Gain more space.
b. Improve the position of your pieces.
2. Decide on what side of the board to play.
a. Queenside: a-c files.
b. Center: d-e files.
c. Kingside: f-h files.
Compare, space, material, and weakness(es)
Play where you have the advantage.
3. DO NOT HURRY. Regroup your pieces, and be patient.

- Slow games (15 or 30 mins).

- Before making a move, double (and triple) check that you are not blundering material (be it in a 1 move capture, or multiple move combination).

- Analyse.

Doesnt want to put in the effort

I'd suggest reading some books, Jeremy Silman has some good ones that would make you a better player if you read them all the way through

"..., you have to make a decision: have tons of fun playing blitz (without learning much), or be serious and play with longer time controls so you can actually think.
One isn't better than another. Having fun playing bullet is great stuff, while 3-0 and 5-0 are also ways to get your pulse pounding and blood pressure leaping off the charts. But will you become a good player? Most likely not.
Of course, you can do both (long and fast games), ..." - IM Jeremy Silman (June 9, 2016)

"... I know that a large percentage of my readers almost exclusively play on the internet – after all, you are reading this on the internet, right!? But there is a strong case for at least augmenting internet play with some OTB play, whether in a club or, better yet, a tournament. Tournament play gives you the kind of concentrated, slow chess that often helps improve your game, especially if you are inexperienced at slow play. ...How often should you play? ... A minimum of 8 OTB tournaments and about 100 slow games a year is a reasonable foundation for ongoing improvement. ... Can’t make 100? Then try for 60. ..." - NM Dan Heisman (2002)
