Domyou mean how to win like the rules? Or just how to get better?
How do you win a chess game?

by first realising how you lose chess games , figure that out and you can avoid making similar mistakes
i recommend post game analysis of a loss , and even flipping the board so you see it from the other players perspective , what attacks they made that won ,
make this part of your armour and it will be you that delivers the final blow more often than not

How do you win a chess game? I mean, I've seen players with 1589 or something. How do they get so good? Please give me some advice.
