Bishop in Chess: How It Moves, Rules, and Strategic Uses

The bishop is chess's long-range piece. From a single open diagonal it can hit a target on the far side of the board without taking a step, which is why players nicknamed it the “sniper.” Each side starts with two of them, locked forever to one square color. Learning to tell a good bishop from a bad one is one of the biggest jumps an improving player can make. This guide covers how the bishop moves and captures, what it's worth, how it stacks up against the knight, and the idea most club players neglect: a bishop boxed in by its own fixed pawns loses most of its power, even if it can still defend. Spotting that early is worth more than any opening trick.

Starting position of the game

Both players possess two Bishops in the starting position of a chess game. They are located at c1- and f1-squares (Highlighted in blue) for White. Similarly, they reside at c8- and f8-squares (Highlighted in yellow) for Black.

As shown in the image above, each player's two bishops sit on different colored squares. This unique identity is crucial to recognize because they can only stay in that color for the rest of the game.
We refer to them as the color of the square they start from. This means that the c1- and f8-Bishops are ‘dark-squared’ Bishops, and c8- and the f1-Bishops are ‘light-squared’ Bishops.

• The Bishop moves diagonally only, as many squares as it wants, in any direction, including backwards.
• It cannot jump over pieces. If something blocks the diagonal, the Bishop stops there.
• It captures by landing on the enemy piece’s square, still moving diagonally.
• Each side starts with two Bishops: one light-squared, one dark-squared. A Bishop never changes its color.
• A Bishop is worth about three points, the same as a Knight. In open positions and endgames it is often worth a bit more.
• Its real strength is range: from one diagonal it can snipe targets on the far side of the board, which is why players nickname it the “sniper”.

Bishop chess moves and captures: the diagonal rule

Using a Bishop often requires a fundamental understanding of the game. Its movement, however, is quite easy.

Now, let’s see the Bishop chess rules.

Unlike a Knight, it cannot move in the initial position because it cannot jump over pieces.

Bishop cannot move on the first move.

Its movement is quite basic, diagonally!

c1-Bishop can move because there is no White piece blocking it.

A Bishop can move anywhere available on that diagonal. As shown above, the c1-Bishop can move to b2- and a3-squares because White pieces do not occupy those squares.

The squares highlighted in yellow demonstrate the available squares for the d4-Bishop.

As highlighted above, the Bishop can scope almost the whole board once there is no piece in front of it. This means that we want to use it and snipe pieces diagonally.

b2-Bishop is on the same diagonal as the f6-Queen.

Like other pieces, it captures the piece once it moves to a square where the enemy piece resides. In the above position, the b2-Bishop can move to the f6-square and capture the enemy Queen.

The dark-squared Bishop captured the opponent’s Queen.

Once it captures the enemy piece, it stands at the square where the enemy piece was. Both dark and light-squared Bishops move the same. Since they can only move diagonally, they must stay in that color forever. However, we need to assess them differently and should not value them the same because the colors matter as the game progresses!

Movement at a glance

• No jumping. The Bishop cannot pass through another piece: a friendly piece blocks its diagonal, while the first enemy piece can be captured. Its own pawns block both Bishops on the very first turn.
• Backwards is fine. Unlike a pawn, the Bishop moves forward or backward along a diagonal, any number of squares, as long as the line is clear.
• Range. From the center it controls up to thirteen squares; pushed into a corner that drops to seven, which is why Bishops want the center or a long open diagonal.

Where the Bishop Came From

The bishop hasn’t always worn a mitre. In the older Indian and Persian forms of the game it was the alfil, an “elephant” that jumped exactly two squares diagonally and could leap over a piece in between. That short, hopping move made it one of the weakest pieces on the board. When chess reached Europe and the rules were modernized around the 15th century, the elephant was handed the sliding, full-diagonal move we use today, and that turned it into the long-range piece we now value. The English name comes from the notch at the top of the piece, which looked to Western players like a bishop’s split hat. Other languages kept different images entirely. The French, for instance, call it the fou, or “jester.”

Why the Bishop is called a “sniper”

Players love giving the Bishop nicknames, and almost all of them come from the same idea: range. A Bishop sitting on a long, open diagonal can hit a target on the other side of the board without moving, so people call it a “sniper”. A Bishop that keeps winning material from far away gets called a “killer Bishop”.

These are not official terms, but they describe the piece well. When you hear someone say their Bishop is “sniping” down the long diagonal, they mean it controls a line the opponent can’t easily block or escape.

Bishop Tactics: Pins, Skewers and the Greek Gift

Because the bishop hits along an unbroken line, it sets up tactics easily. A pin freezes an enemy piece against a more valuable one behind it. A skewer is the reverse: it forces the front piece to move and exposes the target behind. Two long-range pieces lined up on the same diagonal form a battery, and pulling a piece off that line creates a discovered attack. The most famous bishop sacrifice of all is the Greek Gift, Bxh7+, where White gives up the light-squared bishop to rip open the castled king and follow with Ng5+ and Qh5. It only works when the attacking pieces are ready. Count your forces before you commit, because a sacrifice that comes up one move short just leaves you a piece down.

Bishop’s role in chess: what it actually does on the board

A dark-squared Bishop protects and attacks the dark squares and keeps the tactics alive in the dark squares. Similarly, light-squared Bishops operate in light-squares. Players need to think of the board as two separate boards when it comes to this piece.

Placing the bishop on g2 like this is called a fianchetto.

Bishops can protect the King by sticking close to him. This often occurs by ‘fianchettoing’ the Bishop and controlling the same colors nearby. As shown above, the g2-Bishop is covering the nearby light squares. It also rakes the long a8-h1 diagonal. The long diagonals are often preferable for Bishops to stay, as they hit multiple targets and secure many squares. Bishops can also attack the enemy further down the board. Unlike other pieces with the same value, it can control a distant square of its own color that no other piece can reach.

The g2-Bishop has an open ‘a8-h1’ diagonal.

The above image illustrates a g2-Bishop, which serves both defensively and offensively. It protects the f3- and h3-squares and also scopes the ‘a8-h1’ diagonal. Using a Bishop like this often requires precision. Even though it controls the light squares, its absence can hurt White’s position immensely because it plays a vital role in White King’s protection.

The g2-Bishop captured the c6-Knight

In these cases, the threat is much more important than the execution. The above illustration shows an example where the g2-Bishop captures the c6-Knight and doubles Black’s c-pawns. This is often a bad idea because White depends on this bishop as the main defender of the king. The light squares around the White King are now compromised. Many devilish plans (Some of them highlighted in arrows) can be put into action in both the short and long term.

The b2-Bishop can capture the f6-Knight.

The above illustration shows where this trade can be made. The b2-Bishop can capture the f6-Knight because it does not protect the King. Before making such trades, players have to ask themselves the pros and cons. The upside would be to double Black’s f-pawns once the enemy captures the Bishop with the g-pawn. This would leave vulnerable squares around the enemy King. The downside would be to weaken White’s dark squares due to the absence of the dark-squared Bishop.

The value of the Bishop piece in chess: how much is a Bishop worth?

According to conventional principles, a Bishop is worth three points. This is considered equal to a Knight. However, we have seen several examples where the numeric values can change due to the dynamic of the position. Every position is unique, and each Bishop must be assessed separately.

An example of a mistake

One common mistake is misevaluating the position and sacrificing the Bishop for two pawns to launch an attack. In the above position, the f5-Bishop is worth three points. Many amateurs would be tempted to capture the h6-pawn and try to checkmate their opponent.

White is worse.

However, if an immediate checkmate does not occur, White is worse. In the above position, White gave up three points (the dark-squared Bishop) in exchange for two points (two pawns). Since there is no sudden checkmate, the sacrifice was a wrong decision.

An example of a favorable exchange

The above position shows a favorable exchange of a Bishop for a Rook. The f8-Rook is worth five points. Since the h6-Bishop is worth three points, White can capture the f8-Rook and be better. This is also called ‘exchange up’. Bishops and Knights are minor pieces, and Rooks are usually more valuable than them. Queens, of course, are much more valuable, with an estimated nine points.

Bishop vs Knight: which is better?

On paper both are worth three points. In practice it depends on the position.

My own rule of thumb: in an endgame, I’d rather have the Bishop. It works at long range and switches sides of the board in one move, while a Knight needs several.

Bishops in the Opening: Develop Them Early

In the opening your bishops want air. Classical development aims them at the center and the enemy king, like the light-squared bishop landing on c4 to eye f7, the soft spot in Black’s camp. The other main plan is the fianchetto, where you play g3 and Bg2 (or b3 and Bb2) to put the bishop on the long diagonal, raking the whole a8-h1 or a1-h8 line while guarding your own king. The cautionary case is the French Defense, where Black’s light-squared bishop gets boxed in behind the e6, d5 and f7 pawns. That “French bishop” is the textbook problem child. Black often spends several moves just trying to trade it.

The Bishop’s weaknesses and strengths: good Bishops vs bad Bishops and pawn structure

Bishops are great pieces in open positions. In closed positions they are usually weaker, because locked pawns restrict their diagonals and leave them fewer targets.

Example of a Bishop Pair for Black

The above example illustrates how powerful the Bishops are in open positions. They control many squares and prevent enemy pieces from jumping around.

An example of a bad Bishop

The above position shows how Bishop chess pieces can be trapped behind the pawns. If we count the material, it turns out to be equal. However, the game is lost for Black because the g7-bishop is shut out of play.

It is important not to trap the Bishops behind the pawns.

Example of a trapped Bishop

Bishops can also be an easy target for the enemy pawns. This often occurs once a pawn storm is launched against it. The above example shows the b3-Bishop trapped by the enemy pawns on the Queenside.

Example of a passive a2-Bishop

The above position shows a passive Bishop on a2-square. It is held hostage by the opponent’s pawn chain.

In cases like these, the Bishop must be activated using another diagonal. The move c3 is an excellent attempt to use the ‘b1-h7’ diagonal.

The b7-Bishop, on the other hand, is located well. It’s attacking the isolated d5-pawn. If a White pawns were protecting the d5-pawn, that Bishop would not be as effective.

Closed positions are the bishop’s worst enemy.

If the position is closed, the Knights become more favorable than the Bishops. The above position is an example of the c3- and f3-Knights being better than the enemy Bishops. The Knights can jump around and land on critical squares. The Bishops, on the other hand, are restricted and have no target.

The Bishop Pair: Two Bishops Beat Two Knights

Holding both bishops while your opponent has given one up is a real, lasting edge known as the bishop pair. Between them the two bishops cover every square on the board, light and dark, so nothing can hide from them in an open position. Strong players treat the pair as worth roughly an extra half a pawn, and that bonus grows as the position opens and pawns come off. The practical rule is simple. If you own the pair, keep the board open and avoid trading either bishop for a knight without a concrete reason. If you’re the one facing it, lock the structure to blunt their range, or swap one bishop off and break up the team.

Strategies and Techniques with the Bishop: where to put your Bishops (and where not to)

Bishops are often used in long diagonals, eyeing the enemy King.

The c4-square for the f1-Bishop is one of the ideal squares because it controls a long diagonal.

A poorly placed Bishop on the d3-square

The above example shows how a Bishop should not be used. The d3-Bishop would prevent the d-pawn from moving forward. Also, it would not have any scope and be looking at his own pawn. The best way to utilize a Bishop is often to create a safe room to prevent any attack against it.

To avoid giving up the Bishop so early, players often play a3 or a4 to give the bishop a safe retreat square on a2.

What is better than one Bishop? A Bishop pair! Bishops work in harmony because they cover two different colors.

A Bishop pair is all a chess master needs.

Bishops work greatly together because both of them have a distinct job. By uniting, they can reach every square on the board from a far distance. They often create a solid wall once they stand adjacent. This is often useful in endgames when players try to take every possible square from the opponent.

Why I Trust the Bishop in Endgames

I value a Bishop a little higher than a Knight. Knights are easier to navigate and often tricky in fast-time control. In fast time controls, the clock often decides the game. Bishops are very influential in endgames. A Bishop pair versus a Knight pair in an endgame is difficult to hold for the player with the Knights. I recommend players play as many endgames as possible and feel the real strength of the Bishops.

Bishop Endgames You Should Know

Endgames are where the bishop’s range really pays off, but a few specific facts decide results. The most important is the opposite-colored bishops endgame. When each side has a bishop on a different color, the defender can often hold a draw even a pawn or two down, because a blockade on squares the attacking bishop cannot control can stop the extra pawns. Know one drawn trap cold: with the “wrong bishop” and a rook-pawn, the defender can draw by reaching and holding the pawn’s promotion corner, which the bishop cannot control. For mating material, two bishops can force checkmate against a lone king, and so can bishop and knight (though it’s tricky). A single bishop never can.
