El tablero y las coordenadas

Cada casilla tiene un nombre formado por una letra y un número, como en un mapa.

  • Letras (columnas): de la a a la h, de izquierda a derecha.
  • Números (filas): del 1 al 8, de abajo hacia arriba.
  • La esquina inferior izquierda (con blancas abajo) es a1; la superior derecha es h8.
  • El centro del tablero son las casillas d4, e4, d5 y e5 (marcadas).
↓ fila 1 abajo ↑ fila 8 arriba ← columna a columna h →
En la partida: si jugás con negras, el tablero se gira para que tus piezas queden abajo, pero los nombres de las casillas no cambian: e4 sigue siendo e4.

Goal and basic rules

The goal is to checkmate the opponent’s king: attack it so it cannot escape in any way.

  • White moves first, then players alternate turns.
  • You may not make a move that leaves your own king in check.
  • A piece captures another by moving to the square occupied by the opponent’s piece.
Key idea: before you move, ask what your opponent threatens and what will be attacked after your move.

Pieces and moves

KingOne square in any direction. Cannot move into an attacked square.
QueenAny number of squares horizontally, vertically or diagonally.
RookAny number of squares horizontally or vertically.
BishopMoves diagonally and always stays on the same color squares.
KnightL-shape. The only piece that can jump over others.
PawnMoves forward and captures diagonally. From its starting rank it may advance two squares if free.

Rooks, bishops and queens cannot jump over pieces. Pawns cannot move backward.

Special moves

Castling

Move king and rook in one move. Neither piece may have moved, nothing may stand between them, and the king may not be in check or pass through attacked squares.

En passant

If a pawn advances two squares and lands beside an enemy pawn, that pawn may capture it “en passant” only on the very next move.

Promotion

When a pawn reaches the last rank, it becomes a queen, rook, bishop or knight.

Check and checkmate

Check

The king is under attack. You must get out of check: move the king, capture the attacker, or interpose a piece.

Checkmate

The king is in check and there is no legal way to escape. The game ends.

Draws

The game can be drawn by stalemate (no legal moves and not in check), repetition, insufficient material, mutual agreement, or other platform rules.

How to start playing better

1. Develop your pieces

Bring knights and bishops toward the center before moving the same piece many times.

2. Fight for the center

Control e4, d4, e5 and d5 for more space and mobility.

3. Castle early

King safety is usually more important than winning a pawn in the opening.

4. Don’t bring the queen out too early

An exposed queen can be harassed by minor pieces, costing you time.

5. Watch threats

Before every move, review checks, captures and threats for both sides.

Opening principles

The opening is the first ~10–15 moves. The goal is not to “win now”, but to develop pieces, control the center and protect the king.

1. CenterOccupy or control e4, d4, e5 and d5. The center gives space and mobility.
2. DevelopmentBring knights and bishops to active squares before moving the same piece twice.
3. CastlingGet the king safe and connect the rooks as soon as possible.
4. Don’t rushAvoid early queen sorties or hunting rim pawns while ignoring the center.
Classic openings: Italian (1.e4 e5 2.Nf3 Nc6 3.Bc4), Spanish (3.Bb5), Sicilian (1.e4 c5), French (1.e4 e6) and Queen’s Gambit (1.d4 d5 2.c4).

Gambits and opening sacrifices

A gambit offers material (usually a pawn) for fast development, open lines or initiative. If accepted, the opponent must defend accurately; if declined, you still gain space or time.

King’s Gambit

1.e4 e5 2.f4 — White offers the f-pawn to open the f-file, free the c1-bishop and attack the black king quickly. Very aggressive.

Risk: White’s king becomes a bit more exposed. Avoid it if you prefer solid positions.

Queen’s Gambit

1.d4 d5 2.c4 — Not always a true gift: if Black takes (2…dxc4), White often recovers the pawn and dominates the center.

  • Accepted: 2…dxc4 — Black gives up the center for a temporary pawn.
  • Declined: 2…e6 or 2…c6 — keeps a pawn on d5 and seeks solid equality.

Evans Gambit

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4 — Sacrifice the b-pawn for tempi and an open center. Great if you like attacking in the Italian.

Latvian Gambit

1.e4 e5 2.Nf3 f5 — Black replies with a gambit of their own. Very sharp; not recommended for beginners.

Danish / Center Gambit

1.e4 e5 2.d4 exd4 3.c3 — White offers another pawn to open lines and develop with threats.

Budapest Gambit

1.d4 Nf6 2.c4 e5 — Black offers a pawn to activate pieces and annoy White’s center.

Golden rule: if you give a pawn, demand development, concrete threats or central control.
Classic trap: never assume taking the pawn is free. Count defenders and watch checks, pins and back-rank mates.

Essential tactics

Tactics are short sequences that win material or mate. Practicing them is the fastest way to improve.

PinA piece cannot move (or should not) because it would leave the king or a more valuable piece under attack.
ForkOne piece attacks two targets at once. The opponent can only save one.
Absolute pinIf the pinned piece shields the king, moving it is illegal.
Double attackQueen, rook or king attacks two pieces; also check + capture threat.
Discovered attackMoving one piece reveals a check or attack from a piece behind it.
Deflection / decoyYou force a defending piece off a key square.
Remove the defenderCapture or deflect the only piece guarding a critical square.
Back-rank mateRook or queen mates on the last rank because the king’s pawns block escape.
Winning habit: every turn look for checks, captures and threats.

Practical secrets (intermediate)

#1 — Play the position, not your plan.
If the opponent creates a concrete threat, neutralize first, then resume the idea.
#2 — Count attackers and defenders.
Before capturing, add up how many pieces attack and defend that square.
#3 — Pawns control squares too.
An “empty” square may be covered by a pawn.
#4 — Not every check is good.
A check that improves the opponent’s position is a gift.
#5 — In the endgame, the king is an attacking piece.
With few pieces left, the king should move toward the center.
#6 — Passed pawn = clear plan.
Advance it with support; if the opponent has one, block it.
#7 — Trade when ahead in material.
Simplifying pieces usually brings you closer to a won ending.
#8 — Open files belong to the rooks.
Doubling rooks on an open file or the seventh rank is a classic theme.
#9 — Prophylaxis.
Ask: “What does my opponent want?”
#10 — Study your losses.
A repeated mistake is worth more than ten unexamined wins.
