Chess is the longest-running game still gaining strategic discoveries. The current post-Magnus, post-AlphaZero, post-Queen's Gambit era has more amateur engagement than at any time since 1972.
The single biggest tip for the post-beginner stage is to stop studying openings. New players burn weeks memorising the Sicilian Najdorf when they're losing every game in the middlegame to basic tactical patterns. The community recommendation is universal: spend 90% of early study time on tactics puzzles, learn one mainline opening for white and one defence for both Sicilian and 1.e4 e5 for black. That's enough to reach 1600 ELO.
Position evaluation is the hardest skill to learn from books. Knights need outposts; bishops need open diagonals; rooks need open files. A player who can quickly answer "is my bishop better than my opponent's bishop?" is already past the casual barrier.
Modern online platforms (Lichess, Chess.com) have transformed the learning curve. Free engine analysis after every game, free puzzles, free adaptive bots — the resources available in 2025 didn't exist in 2018.
