Any great chess player (let's define that as near-IM fide ratings and up) will tell you that it's a highly iterative process between practice, analysis and reading that is very much anchored around practice.

They play thousands and thousands of hours and, yes, also spend quite a bit of time reading, thinking, analyzing (both their own and others') games and learning from mentors/teachers. However, practice is king and all the reading/analysis would be worthless in its absence. They would have no anchors to grab onto in your brain - no way to really become operational.

A chess "player" that mostly reads, studies and analyzes with a little bit of practice sprinkled in between would indeed be hilariously weak.

Take a beginner player who has been playing at the local chess club once a week (two hours) for 12 weeks. This player enjoys the game and wants to be better. He plays anyone who will give him a game. He occasionally wins against other beginners. He loses to the stronger players when he gets a chance to play them. This player has 24 hours available to work on chess over the next 12 weeks. What is the best way for this player to improve? Suppose the options are, 1) continue attending chess club for the next 12 weeks, or 2) stay at home and study two hours a week for the next 12 weeks. The study material is Logical Chess Move By Move by Irving Chernev (mentioned above by msluyter). The book covers 33 master-level games in two categories: kingside attack, and queen's pawn opening. Chernev, a Grandmaster, explains the reasoning behind every move in all 33 games. When the player shows up at chess club on week 25, will he be better off having chosen option 1 or option 2?
