How the bishop moves in chess

Alexey Mudry · updated September 12, 2026
The bishop moves along diagonals only - any number of squares, forwards or backwards. The rule is short, and the consequence is serious: the square a bishop starts on decides the colour it will travel on until the last move of the game. A bishop can never change colour. The other pieces - how chess pieces move.

How the bishop moves

Along diagonals in any of four directions, as far as you like, until the board ends or a piece appears. A bishop does not jump: an enemy piece in the way can be captured, a friendly one closes the road.

A bishop on d4 controls 13 squares - and every one of them is the same colour as d4. Squares of the other colour do not exist for it.

It captures exactly as it moves, taking the square of an enemy piece. There is no separate capturing rule.

At the edge a bishop is noticeably weaker: from e1 or from a corner it holds seven squares instead of thirteen. The reason is simple - a corner has one diagonal leaving it instead of four.

A bishop is tied to its colour for good

A diagonal step always lands on a square of the same colour. So a bishop that begins the game on a light square will travel on light squares for a hundred moves - half the board is permanently out of reach.

That is why bishops are described by colour rather than by position: light-squared and dark-squared. This is not slang but a working idea: "Black's dark squares are weak" means the dark-squared bishop has been traded off and there is nothing left to guard them.

Four bishops in the starting position. Each side has one on a light square and one on a dark square - together they cover the whole board.

Hence the point about trades: when you give up a bishop you are not giving up "three pawns", you are giving up control over half the squares. The value scale does not show that - it is in the overview of the moves.

A bishop can be shut in completely

A bishop's range only works on an open board. Block four diagonals and it has no move at all, although the piece is intact and sitting in the centre.

Not a single move: four friendly pawns have closed every diagonal. A bishop in the middle of the board, completely out of play.

In a real game this happens with one or two of your own central pawns rather than four, and it is called a "bad bishop": it is hemmed in by its own pawns and stares at their backs. The cure is either to reroute the bishop to a free diagonal or to push the pawns that block it.

The same property drives the comparison with the knight: in a closed position the knight is stronger because it jumps, while on an open board the bishop wins - it reaches both wings in a single move.

Two bishops are worth more than two bishops

On its own a bishop is worth three pawns, the same as a knight. But a pair of bishops is rated above a pair of knights and above bishop-and-knight - precisely because together they cover both colours and the opponent has no safe squares left.

In practice: a trade that leaves you with two bishops while the opponent has bishop and knight is usually good, even when the pawn count is level. Chess literature calls it the advantage of the two bishops.

The other side of the coin is an endgame with opposite-coloured bishops. When each side has one bishop and the colours differ, the bishops can never meet or interfere with each other: such positions often end in a draw even a pawn or two down. All the ways a game can be drawn - draws in chess.

What the bishop looks like and where it stands

A bishop is a mid-height piece with a slanted cut on top, resembling a mitre - which is where the English name comes from. In Russian the piece is an elephant, in French a jester, in German a runner; the move is the same everywhere.

A bishop next to a pawn: the bishop is taller and has a cut in its head. They are only confused in small travel sets.

Each side has two bishops, standing next to the king and the queen: White on c1 and f1, Black on c8 and f8. In notation a bishop is B.

In the opening bishops are usually developed after the knights but before the rooks and queen: they need a pawn to move first and open a diagonal. How that looks in practice - openings for White. The full setup - board setup.

See the colour rule for yourself

Put a bishop on a light square in the board editor and try to walk it to a dark one. It becomes obvious why this property matters more than the rule of the move itself.

Common questions about the bishop

How does the bishop move in chess?

Along diagonals only, any number of squares, in any of four directions. It does not jump: an enemy piece in the way can be captured, a friendly one blocks the road. It captures exactly as it moves.

Can a bishop move backwards?

Yes. A bishop moves diagonally in any direction, including back towards its own side. The pawn is the only piece that cannot move backwards.

Why can a bishop never change colour?

Because every diagonal step lands on a square of the same colour. A bishop that starts on a light square stays light-squared for the whole game, and half the board is permanently out of reach. That is exactly why a pair of bishops is valued above one.

How many squares does a bishop control?

Thirteen from the centre, seven from the edge or a corner. The difference comes from how many diagonals leave the square: four from the middle, one from a corner.

Which is better, a bishop or a knight?

On paper they are equal at three pawns each. On an open board the bishop is stronger - it reaches both wings in one move. In a closed position the knight is stronger, because it jumps over pawns while the bishop has nowhere to go.

What are opposite-coloured bishops?

An endgame where each side has one bishop and the two travel on different colours. Such bishops can never meet or block each other, so the game often ends in a draw even when one side is a pawn up.

Where do the bishops start?

Next to the king and queen: White on c1 and f1, Black on c8 and f8. Each side has one light-squared and one dark-squared bishop - between them they cover the whole board.

How to run a tournament without being an arbiter

No arbiter skills required. The app takes over the part that usually stops people from running tournaments at all: who plays whom in each round and who finishes first.

  • Swiss system
    works for ten players and for fifty
  • Round robin
    for a small group that wants to play everyone
  • Free meetup
    for those who do not need a bracket at all

More than a bot: the app, FIDE rules and a TRF report

  • The app. Besides the bot there is an app - inside Telegram and simply at playvibechess.com/app: what is on in your city, the player list, a live table, the current round, your profile and game history - everything that is awkward to read as chat messages.
  • Pairings by FIDE rules. Pairings are computed by bbpPairings, an open-source engine implementing the Dutch system: score groups, floats on an odd field, colour alternation, no rematches and no two byes in a row.
  • A TRF report. A finished tournament exports as a single file in the FIDE data exchange format - the one arbiter software and federations accept. Your profile stores the FIDE ID, national federation code, title, sex and date of birth for it.
  • Free. All of the above, with no subscriptions, paid plans or limits on the number of tournaments and players.

The bot is constantly improved based on real tournaments. If you need a feature that isn't there yet, message the developers right inside the bot with the /support command. Many features appeared exactly because organizers asked for them, and useful ideas get added quickly.

What to read next

The usual comparison is with the knight - they cost the same. A queen moves like a bishop and a rook together - queen. Nearby - king and pawn.
