why could I beat my friend that is over 1000 but I can't get in that level in this game
I played someone a few games after they learnt how the pieces move and I randomly blundered my queen and lost. In Chess, you may develop strong logic, but raw beginner play can still beat you in 1 move, glass cannons may seem silly for example, prematurely attacking, but are really lethal if you mistep even once throughout the game. The positions also get unfamiliar, and some personality types feel easier or harder to your style, so your kingside fianchetto-obsessed friend may be really passive and you have an easy time setting up on them, but your hyper-aggressive cousin trips you up every time with offbeat unsound play. You would need to work on that gap you lack seeing patterns and ideas in. The cool part is you can still enjoy chess with your friends even after you surpass them because they can still win. Also if you Trade Monger long enough without error, your friend probably isn't consistently foreseeing won endgames, you will probably get a winning endgame or a draw by default.
