Chess

Chess is a complete-information strategy game with centuries of accumulated theory. Online play and free training tools have made improvement far more accessible than in any previous era.

Progress at the beginner and intermediate level comes almost entirely from tactics and avoiding blunders rather than opening theory.

Play regularly online and analyse your losses with an engine afterward.

Drill tactics puzzles daily. Below expert level, tactics decide most games.

Learn opening principles rather than memorizing long opening lines.

Study basic endgames — king and pawn especially. They convert winnable positions into wins.

Chess is effectively free, and the free tools are the best ones.

• A free account on Lichess or Chess.com. Lichess is fully free and open source with no paywalled analysis. Both give you unlimited opponents at your level, tactics training, and engine analysis that would have been world-class-coach territory thirty years ago.
• Nothing else is required.

If you want a physical set:

• A tournament-standard set ($30–60). Plastic Staunton pieces with a roll-up vinyl board, 3.75" king. This is what actual tournaments use, and it is inexpensive.
• A chess clock ($30–50) only if you play over-the-board games seriously.

Books worth owning eventually, once you have a rating around 1200+: an endgame primer and a well-regarded tactics collection. Buy these after you have played a few hundred games, not before.

Skip: opening encyclopedias, expensive wooden sets, and paid opening courses. None of them help below intermediate level.

Your first month

1. Learn the rules cold, including the ones beginners miss: castling, en passant, promotion, stalemate, and the draw conditions.
2. Learn the three opening principles — control the center, develop your pieces, castle early — instead of memorizing opening lines.
3. Play slower time controls. Ten minutes or longer. Blitz and bullet are fun and they mostly train you to move fast, not to think well.
4. Do tactics puzzles daily. Fifteen minutes is plenty. Below intermediate level, games are decided almost entirely by tactics and blunders.
5. Analyse every loss. Find the move where it went wrong before turning on the engine, then check yourself against it.

Beginner → Intermediate → Advanced

• Beginner (under ~1000): Stop hanging pieces. Nearly all games at this level are decided by one-move blunders, not strategy.
• Intermediate (~1000–1600): Tactical patterns, basic endgames, and simple plans. You start losing to positional errors rather than immediate blunders.
• Advanced (1600+): Deeper strategy, prophylaxis, and an actual opening repertoire — the point at which opening study finally pays off.

• Studying openings first. The most common misallocation of effort in chess. Below intermediate level, games are decided by hanging pieces, not by move 12 of the Sicilian.
• Playing only fast time controls. Bullet and blitz are enjoyable but they train pattern recall under panic rather than calculation. Improvement comes from slow games.
• Not checking what the opponent threatens. Before every move, ask what changed about their last move. This single habit is worth hundreds of rating points at the beginner level.
• Moving the same piece repeatedly in the opening while your other pieces sit at home undeveloped.
• Bringing the queen out early. It gets chased around the board and you lose tempo developing everything else.
• Never studying endgames. King and pawn endings are the highest-value study in chess and almost nobody does them. Winning positions get drawn constantly for lack of technique.
• Only analysing wins. Losses contain all the information.

Do I need to be good at math?

No. This is a persistent myth. Chess rewards pattern recognition, memory, and calculation of concrete variations — not mathematical ability.

How long to get decent?

With daily tactics and regular slow games, most people reach a comfortable club-level strength (around 1200–1400 online) within six months to a year. The curve is steep at first and then flattens considerably.

How many openings should I learn?

One as White and one against each of the main replies as Black. That is genuinely sufficient until well into intermediate. Depth in a few beats shallow familiarity with many.

Is playing the computer good practice?

Engines are excellent for analysis and poor as opponents — they play at superhuman strength or artificially weakened strength that blunders unnaturally. Play humans, analyse with engines.

Am I too old to start?

No. You are unlikely to become a grandmaster starting as an adult, but reaching a strong club level is entirely achievable at any age, and that is where the vast majority of enjoyment lives anyway.
