HOW TO BEAT A REALLY GOOD PLAYER

1. play a game against him
2. record the moves he makes
3. check with a chess engine what your best move against his moves would be
4. record the moves the engine suggests
5. play against him again with the same color you played as before
6. play the move that the engine suggested (this will work because he will probably play the same opening every time.)
7. repeat steps 1-6 until you win
That would be cheating .

engine use before game is technically preparation/analysis

900 rating means he understands a bit now and u cant just play the regular 400 ways, its a different league

The most important thing for you at the moment is to learn how to checkmate. In your last game you were easily winning but then it ended in a draw because you did not know how to checkmate https://www.chess.com/game/live/11202878603?username=jacob101710
You have only played the live games so far. The daily games are different in that you have a whole day (or longer) to decide on your next move. Taking longer to think up the best move is a good way for many people to improve faster when they are getting started. Those games are also easier to arrange around both players schedules. For example you can go to school one day then go home do some homework, have dinner then login here and make your next move. The key point is you can play whenever suits you.

Without doing hard work if you will think that if someone tells you advice by listening to advice but it won't make you better that person who is strong one day he was too a beginner but he did enough that made him improve

Jacob, you don't seem to want to play me anymore so I'll just wrap up with my conclusions based on the few moves that we played together:
You should take some time to decide whether this game is for you. At your age you have plenty of time ahead of you to improve immensely, but you need to decide whether you are willing to invest the time and effort needed to make those improvements. No player ever has a realistic chance of beating some who is more than 800 points above them. It is still useful to play against much stronger opponents from time to time, to see what can be learned from the game.
You have good attacking instincts but need to learn about King safety, piece coordination and protecting your pieces. There are many beginner chess books that will teach you these things. The lessons on this site can also help you, or there are other sites such as chess factor, or other mobile apps such the magnus trainer which can teach you those skills and more.
that is way easier said that done

Play with queen and both rooks odds.
Jokes aside, I don’t really know. Maybe the Blackburne shilling trap in a fast game? If you are black:
that is way easier said that done
unless you check with a chess engine after each game

Dude it's not like you can beat a player 600 rating points higher than you by checking the engine, chess is not easy
