well then you might want to learn an opening called the london system. for white. and the caro kann for black. Since I can't teach everything at once you might as well watch youtube for it. I recommend Chesspage1's videos because he is very engaging and engagingness is key to high retention.
ok. thanks @Dbickbro i hope i will beat him with caro kann. also watch videos about IM GothamChess, AKA Levy Rozman
