Pick an e4 opening as white, d4 tends to lead to more complex play. Play the opening over and over analyzing mistakes to become familiar with best play.
Pick a defense for both e4 and d4 and apply same principles as above.
There are tons of YouTube channels that will explain different openings and their main ideas.
When reviewing your games emphasize the point where you have finished developing. If you prefer your position over your opponent most of the time then you are in a good position to move on.
Mid game; try to figure out your opponents objective.
Set long term goals. Consider your pawn structure before advancing or exchanging.
Consider king safety earlier in game, don't advance your f pawn unless you have good reason, especially if the queens are still on.
At lower level play, attacking the king is often more effective then attracting pieces. Tactics, tactics, tactics
Endgame. Take the time to count.
Learn from your mistakes. Review your games. Ask questions. Figure out at what point the game went wrong. What were you thinking about when it did? Don't beat yourself up for mistakes, but focus on stuff you overlooked or calculated wrong.
Hello, I'd like to work on my chess game and gather study material that is helpful for someone just starting to work on his game. I have poker background, so I am familiar with analyzing spots and strategic approach to game.

I always played chess for fun, but I'd like to actually learn it now and work on my game.
I understand concepts as openings and defending them are basic stuff to start with, reviewing my game and looking for better spots, endgame.. but what else should I also be looking at?
Could you share any videos or literature that you would recommend to someone starting out, that helped you in a profound way?
Thank you
