Will try that channel for sure! Thank you!
Is reading books about chess strategies/tacticts/openings really necessary to become a good player?

I've only ever had 1 book and I've never really used it. I've gotten better by watching youtube and playing correspondence chess. I think correspondence chess it the best way to improve as it gives you as much time as you need to think things through.
Here are some playlists on youtube that will make you a much better player:
Chess Fundamentals - John Bartholomew
Beginner to Chess Master - Chessnetwork
This is fantastic free content that I would recommend to just about anyone. Even advanced players can learn from these playlists.
Thanks alot! Will definitely look try correspondence chess on this site and will look into the channels!

Well, I gotta admit I do prefer rather to play than read but I guess if I forced myself to read and learn a bit after every few games I could become "good". Thanks for your input!

Thanks for the links! Chessable is really good, I can access some of the books right away! Cheers!

"Back in the day, people didn't have books and still were good."
Yes they did have books like those by world champions Lasker and Capablanca. Many such books are legally FREE on the Internet!
Links to pdf-file books by those authors and much more are here: http://bishopsbounty.blogspot.com/2009/01/free-online-chess-books.html
Many more resources are here: http://billwall.phpwebhosting.com/
Having outside input just gets geniuses there faster but takes normal people further than they would otherwise go. Chess.com has some good study material.
I am new to this forum and can't find my way quite around, would you mind sending me links to those study materials, please? Thanks and I agree with you, that sounds just right.
In your upper left drop down, go learn, then tactics or lessons or drills.
Chassable has some good free lessons, but just no where near as many total. I recommend doing all their lessons in a day or two and then coming back here afterward.

No, but it is a common way to learn, and you need to apply what you learn. Top players learn by spending their time playing strong opposition, analyzing, and resting.

Nope, I learned everything just by playing and revising my ideas. Do play longer time controls though, short time controls won't teach you anything.

"... If it’s instruction, you look for an author that addresses players at your level (buying something that’s too advanced won’t help you at all). This means that a classic book that is revered by many people might not be useful for you. ..." - IM Jeremy Silman (2015)

I just started using Chessable a few days ago and I like it a lot. There are a lot of books that you can immediately access for free, including some by John Bartholomew.
