I recommend reading the book "Murman's Book of Poker".
A little about the author:
Chris Moorman, became famous under the nickname "Moorman1".
He is considered to be the most successful online tournament player. He has won over $ 14,000,000 in online tournaments and over$ 5,000,000 in live events.
"Murman about Poker" is the author's first book. In 2017, he released his second autobiographical book.
I am learning a little every day, the first thing I read was "The Mentality of a Poker Player" and "Smashing the Micro Limits". At the time I read "Harrington on Hold'em vol. 1" but as the game has changed a lot from the time the books were written to the present, they will help you to learn part of the game and strategies, so I recommend reading books and all kinds of current information which will be much more useful to you.
