In chess, a check is when the opponent's king is under threat of capture. The player must make a move to get their king out of check, either by moving the king, capturing the threatening piece, or blocking the attack. Checkmate, on the other hand, is when the opponent's king is in check and there is no legal move that can be made to get out of check. This results in the game being over and the player delivering checkmate wins the game. **
