Beginners are often told to memorise openings — twelve moves of the Italian Game, eight of the Sicilian. Then the opponent plays something unexpected on move three and the memory work evaporates. Principles beat memorisation, because principles explain why. Master these ten and you'll come out of almost any opening with a healthy position — against anyone below club level.
1. Fight for the centre
The four central squares (e4, d4, e5, d5) are the high ground: pieces placed there, or controlling them, reach more of the board. Open with a centre pawn — e4 or d4 — and develop pieces so they aim at the middle. When you don't know what to do, adding pressure to the centre is rarely wrong.
2. Develop knights and bishops quickly
Every move in the opening is a race to bring your army out. Knights first (they're short-range and take longer to reach good squares), then bishops. A piece on its starting square is a soldier still in bed.
3. Don't move the same piece twice
Each repeated move on a developed piece is a free move for your opponent's development. Unless there's a concrete tactical reason — you win material, or you must respond to a threat — develop something new instead.
4. Castle early
Castling does two jobs in one move: tucks the king behind a wall of pawns and connects your rooks. Aim to castle within the first ten moves. Every extra move your king spends in the centre is an invitation — open files appear suddenly, and centre-stranded kings lose games in one tactic.
5. Keep the queen home (for now)
The early queen sortie is the most tempting beginner mistake. A queen in the open gets chased by enemy minor pieces — each chase move develops their army while your strongest piece runs in circles. Scholar's Mate threats feel clever until someone defends correctly and you're three tempi behind.
6. Connect your rooks, then find them files
Once minor pieces are out and the king is castled, your rooks should see each other along the back rank. Rooks want open or half-open files — they do nothing behind their own pawns. "Develop, castle, connect rooks" is a complete, honest opening plan.
7. Don't grab pawns while behind in development
That b2 pawn (or its mirror on b7) is famous poison. Spending two queen moves to win one pawn while your opponent develops two pieces is a terrible trade — development converts into attacks, and attacks convert into material with interest.
8. Make a threat, but make it useful
Threats that also develop (a knight that attacks a pawn from its best square) are gold. Threats that only threaten (a bishop lunge that gets kicked by a pawn) hand back the tempo. After every candidate move ask: if my threat is parried with a natural move, am I better off or worse?
9. Take the centre when it's offered free
If your opponent ignores the centre, occupy it — two pawns abreast on e4/d4 cramp their whole game. Space is a long-term advantage that never evaporates: more room means your pieces coordinate and theirs trip over each other.
10. Know why gambits work — and decline politely
A gambit offers a pawn for faster development. As a beginner you don't need to memorise refutations: either accept and give the pawn back at the first convenient moment, or decline with a solid developing move. What loses games is greed — clutching the extra pawn while your opponent's entire army aims at your king.
A practice routine that works
Play the RivalPit computer on Easy and follow the checklist — centre pawn, knights, bishops, castle — every single game, even when a "clever" move tempts you. When your openings feel automatic, raise the difficulty, then set a time control (try 10 minutes) so decisions come under mild pressure. The principles hold at every speed; they just get faster to apply. When the middlegame arrives and you don't know the plan: improve your worst-placed piece. It's principle zero, and it never expires.
