How Many Bishops Can You Have in Chess?

Quick answer: maximum bishops in chess

One player can legally have up to 10 bishops in chess. That means the original bishops are still on the board, and all 8 pawns have promoted to bishops.

Both players together can theoretically have up to 20 bishops: 10 white bishops and 10 black bishops. Promotion changes pawns into bishops; it does not increase the total number of pieces on the board.

2 bishopsEach side starts with 2 bishops: one light-square bishop and one dark-square bishop.

Why the answer is 10, not 11

A player starts with two bishops and eight pawns. Since only pawns can promote, and each pawn can promote only once, the maximum bishop count for one side is 2 original bishops plus 8 promoted bishops.

Promotion is a transformation, not a new piece being added to the board. If a pawn becomes a bishop, that pawn stops being a pawn and becomes the promoted bishop.

Why bishop promotions are rare

The legal maximum is 20 bishops, but serious games do not get close to that. Bishop promotions are rare because players usually prefer the power of a queen.

When a bishop promotion does happen, it is usually for a concrete reason: a diagonal check, a stalemate trick, or a position where queen promotion would fail tactically.

These answers explain maximum bishop count, promotion, spare bishops, captured bishops and common bishop-count confusion.

Main bishop count

How many bishops can you have in chess?

One player can legally have up to 10 bishops in chess: 2 original bishops plus 8 promoted pawns that all become bishops. Both players together can theoretically have up to 20 bishops on the board. Use the bishop calculator on this page to test the count.

Can you have two bishops in chess?

Yes. In fact, each player starts with 2 bishops. A promoted bishop is an extra bishop beyond the two original bishops.

Can you have more than 2 bishops in chess?

Yes, you can have more than 2 bishops. Every pawn that reaches the last rank can promote to a queen, rook, bishop or knight, so several promoted bishops are legal.

Can you have 10 bishops in chess?

Yes, one side can legally have 10 bishops if both original bishops remain and all 8 pawns promote to bishops. It is extremely unlikely in a real game, but it is legal.

Can you have 11 bishops in chess?

No, one side cannot have 11 bishops in a legal game. A player starts with 2 bishops and only 8 pawns can promote, so the maximum for one side is 10 bishops.

How many bishops can both players have together?

Both players together can theoretically have up to 20 bishops: 10 for White and 10 for Black. That means all 4 original bishops are still present and all 16 pawns have promoted to bishops.

How many bishops does each player start with?

Each player starts with 2 bishops. White starts with bishops on c1 and f1, and Black starts with bishops on c8 and f8.

How many bishops are on the board at the start of chess?

There are 4 bishops on the board at the start of chess: 2 white bishops and 2 black bishops.

Promotion and extra bishops

How do you get extra bishops in chess?

You get extra bishops by promoting pawns. When one of your pawns reaches the last rank, you may choose to turn it into a bishop.

Does pawn promotion add a new bishop?

Promotion can create a new bishop on the board, but it does not add an extra piece overall. The pawn changes into a bishop, so your total number of pieces does not increase.

Can every pawn promote to a bishop?

Yes, every pawn can promote to a bishop if it reaches the last rank and the player chooses bishop promotion. There is no rule limiting a player to one promoted bishop.

Do you need a captured bishop before you can promote to a bishop?

No, you do not need an original bishop to be captured before promoting to a bishop. You may promote to a bishop even if both starting bishops are still on the board.

Can you promote to a bishop if you already have a bishop?

Yes, you can promote to a bishop even if you already have both original bishops. That is how a player can have three or more bishops.

Can you choose not to promote to a bishop?

Yes, you can promote to a queen, rook or knight instead of a bishop. Choosing rook, bishop or knight instead of queen is called underpromotion.

Can a promoted bishop turn back into a pawn?

No, a promoted bishop cannot turn back into a pawn. Once a pawn promotes, it remains the chosen piece until it is captured.

Can a bishop promote to another bishop?

No, bishops do not promote. Only pawns promote when they reach the last rank.

Maximums and limits

Can you have two bishops on the same colour squares?

Yes. A player normally starts with one light-square bishop and one dark-square bishop, but promotion can create extra bishops on either colour complex.

Can you have three bishops in chess?

Yes, one side can have three bishops if one pawn promotes to a bishop while both original bishops are still on the board.

Can you have four bishops in chess?

Yes, one side can have four bishops if two pawns promote to bishops while both original bishops are still present.

What is the maximum number of promoted bishops for one side?

The maximum number of promoted bishops for one side is 8, because a player starts with 8 pawns and each pawn can promote only once.

What is the maximum number of promoted bishops in the whole game?

The maximum number of promoted bishops in the whole game is 16, because both sides start with 8 pawns each.

Can a legal game have more than 32 pieces after promotion?

No, a legal game cannot have more than 32 pieces on the board. Promotion changes a pawn into another piece; it does not add a new piece to the board.

Can one side have more than 16 pieces after promotion?

No, one side cannot have more than 16 pieces after promotion. A side starts with 16 pieces, and promotion changes pawns into other pieces rather than increasing the total.

Physical pieces and practical play

What if you do not have an extra bishop piece?

If you do not have an extra bishop piece, you should use a clear substitute and make sure both players know what it represents. In organised play, ask the arbiter or tournament director.

Do spare bishops count as legal bishops?

Spare bishops are physical pieces used for convenience after promotion. They do not change the legal starting count, which is still two bishops per side.

Can you use an upside-down rook as a bishop?

In casual play, players sometimes use an upside-down rook to represent a bishop. In formal play, it is better to use a real bishop or ask an arbiter so there is no confusion.

Can two bishops stand on the same square?

No, two bishops cannot stand on the same square in a legal position. Each square can hold only one piece at a time.

Can a player have no bishops in chess?

Yes, a player can have no bishops if both original bishops have been captured and no pawn has promoted to a bishop.

Is having extra bishops usually good?

Having extra bishops can be useful for diagonal control, but it is not automatically better than promoting to a queen. The bishop-count calculator shows material count, not a guaranteed result.

Is the 20-bishop maximum realistic in serious games?

No, the 20-bishop maximum is a theoretical limit, not a realistic expectation in serious games. In practical chess, bishop promotions are rare and usually happen for a specific tactic such as diagonal control, stalemate avoidance or an immediate check.

Where should I study more bishop rules?
