Hello everyone. How's it going? Recently reached 1400 on Rapid (chess.com). My next goal is to reach 1500 and participate in the OTB tournament (U1800) for the second time. That's why I've started solving as many puzzles as I can. At the same time, I'm planning to start reading Mihail Marin's book to prepare for the opening. I'm open to any advice or ideas from the experienced players here.

Tilted almost 100 points a few days ago, but just broke a new all time high today in blitz 🚀

What kind of videos should i watch to further my understanding of chess and to get past 1000 elo i am currently 600

Is it better to learn the opening first or the end games?
