How to get better at chess.


The best advice I can give, as a player who's still 1200 after like 30 thousand games played, is not to rush anything. I end most of my 10 min games with 5-7 minutes on the clock, and I hate myself for that. Take your time, don't waste it but make sure not to lose any pieces for no reason. Beware of sniper bishops from the other side of the board! 1000 is not hard to reach, I believe in you!
Always blunder check before you move.
Whenever you lose a game, analyse it thoroughly to learn from your mistakes.

Do tactics. Yes only doing tactics will get you 1200 for sure. While doing tactics you also improve board vision, board vision will help you blunder less. Also I wouldsay start reading "winning chess strategy by yasser seirawan" by reading that book you would understand how to make plans.
