Professor Archer says: The confusion between check and checkmate is so universal among beginners that I consider it the very first thing to clear up. I have seen students celebrate a check as if they have won the game, and I have seen them resign in positions where their king had a perfectly good escape square. Getting this distinction absolutely clear in your mind is the foundation of everything else in chess.
Check: A Threat to the King
Check occurs when a piece directly attacks the opponent's king. It is a threat, not an outcome. When your king is in check, you must respond immediately - no other move is legal until the check is resolved.
There are always three possible responses to check. You can move the king to a safe square. You can block the attack by placing a piece between the attacker and your king (this works against bishops, rooks, and queens, but not against knights or pawns). Or you can capture the piece giving check.
As long as at least one of these three options is available, it is just check. The game continues. Your king is in danger but not yet defeated. Check can happen dozens of times in a single game, and most checks are survivable.
A Check Position - The King Can Escape
In this position, the white rook on e1 gives check to the black king on e8. But this is only check, not checkmate. Black has several options: the king can move to d7, d8, f7, or f8. Black could also block the check by placing a piece on e7, or potentially capture the rook if a black piece can reach e1.
Because Black has legal responses, the game continues. This is a critical moment but not a decisive one.
Check: the rook attacks the king on e8, but the king has multiple escape routes.
A Checkmate Position - No Escape
Now compare this position. The white rook on e8 delivers check, and the black king on g8 has nowhere to go. The squares f8, g7, h8, and h7 are all controlled by White's pieces. No black piece can capture the rook or block the attack.
This is checkmate. The king is in check, and none of the three escape methods - move, block, or capture - works. The game is over immediately. White wins.
Checkmate: the rook on e8 gives check, and the king has no escape. Game over.
How to Tell the Difference
When you see a king under attack, run through a quick mental checklist to determine whether it is check or checkmate.
First, can the king move? Look at every adjacent square. Is each one either occupied by a friendly piece or controlled by an enemy piece? If even one square is safe, it is just check.
Second, can any piece block? If the check comes from a bishop, rook, or queen (pieces that attack along lines), is there any friendly piece that can jump into the line between the attacker and the king? If so, it is just check.
Third, can anything capture the attacker? If a friendly piece can take the checking piece without exposing the king to another attack, it is just check.
Only if all three answers are "no" is it checkmate. Beginners often miss one of these options in the heat of the moment. Take your time and check all three every time.
Check vs Checkmate Questions
Can you give check and checkmate at the same time?
Not exactly. Checkmate inherently includes check. Every checkmate is a check, but not every check is a checkmate. When you deliver checkmate, you are giving check that happens to have no escape. They are not two separate events.
Is it better to give check or plan for checkmate?
Always plan for checkmate rather than giving random checks. A check without a purpose wastes a move and gives your opponent time to reorganize. Strong players use check as a tool within a larger plan, not as a goal in itself.
Can a pawn deliver checkmate?
Absolutely. Any piece can deliver checkmate, including a pawn. If a pawn attacks the king diagonally and the king has no escape, that is checkmate. Pawn checkmates are rare but perfectly legal and quite satisfying.
What if I think it is checkmate but my opponent claims they have a move?
In tournament play, the arbiter resolves disputes. In casual play, examine the position carefully together. Check every possible king move, every possible block, and every possible capture. If even one legal response exists, it is check, not checkmate.
Professor Archer says: Think of check as a warning bell and checkmate as the final buzzer. When the bell rings, you still have time to act. When the buzzer sounds, the game is over. Every time you give check, ask yourself: can they escape? If the answer is no, you have not given check - you have delivered checkmate. Learning to see the difference before you move is what turns a casual player into a serious one.
Quick Quiz
The black king is on h8. A white queen on h7 delivers check. The only adjacent squares are g8 (blocked by a black rook) and g7 (controlled by the queen). What is the result?
- Checkmate - the king has no escape - Be careful. The black rook on g8 might be able to capture the queen on h7 or block in some other way. You need to verify that no piece can capture the queen or interpose before declaring checkmate.
- It depends on whether any black piece can capture or block (Correct) - Correct. You cannot determine checkmate just by looking at king moves. You must also check whether any other black piece can capture the queen on h7 or block the check. If no piece can help the king, it is checkmate. If any piece can intervene, it is just check.
- Check - the king can move to g8 - The problem states that g8 is blocked by a black rook (a friendly piece). The king cannot move to a square occupied by its own piece. However, the rook itself might be able to help - check all possibilities.
- Stalemate - the king cannot move - Stalemate only occurs when the king is NOT in check. Since the queen is delivering check, this cannot be stalemate. It is either check (with a way out) or checkmate (with no escape).
