Rules

Chess is played on 64 squares; the goal is checkmate – attacking the enemy king so that no escape remains.

The moves in brief:

• Pawn: one square forward (two from its starting square), captures diagonally. On reaching the last rank it promotes – you pick a queen, rook, bishop, or knight in the promotion dialog.
• Knight: the L-jump, the only piece that leaps over others.
• Bishop moves diagonally, rook in straight lines, the queen both – any distance.
• King: one square in any direction. Castling tucks the king away and develops the rook in one move – allowed only if neither has moved, nothing stands between them, and the king does not cross an attacked square.
• En passant: if an enemy pawn double-steps past your pawn, you may capture it in passing – but only on the very next move.

If your king is in check you must address it – our board only allows legal moves anyway, and tapping a piece shows every square it can go to. A game without checkmate ends in a draw: stalemate, repetition, the fifty-move rule, or insufficient material – the status line always tells you which.

Strategy

Four principles carry you further than any memorized opening:

Center and development

Control the middle (e4, d4, e5, d5) and bring knights and bishops out early. Try not to move the same piece twice in the opening, and keep the queen home a little longer – early queens get chased with loss of time.

King safety

Castle early. A king stuck in the center is the most common cause of quick defeats – even against our lower levels.

Don’t hang pieces

Most games below club level are decided by giveaways. Before each move, ask: what is my opponent attacking right now? Is the square I’m moving to defended? That is what the move preview is for – it shows where you can go; whether it is safe is your call.

Grow with the levels

Levels 1 and 2 make deliberate, human-like mistakes – take your time to spot and punish them. Beat a level twice in a row, move up one. From level 6 the engine plays at a capped competitive strength, and level 8 calculates freely – there, a draw is already an achievement. At the top levels the engine takes a few seconds per move to think – that comes with the territory.

History

Chess arose some 1,500 years ago in India as chaturanga, travelled through Persia (“shāh māt” – the king is defeated) into the Arab world and on to Europe, where around 1500 the queen and bishop gained their modern powers. The game has been essentially unchanged since – one of the oldest continuously played strategy games in the world.
