At the most basic level, chess involves the physics of classical mechanics, which is the branch of physics that studies the motion of objects. When you move a piece on the board, you are essentially imparting force on it and causing it to move according to the laws of motion.

Dynamics

The movement of pieces in chess can also be analyzed in terms of dynamics. For example, the potential energy of a piece can be calculated based on its position on the board and the positions of other pieces. This can help players make decisions about which moves to make in order to maximize the potential energy of their pieces and minimize the potential energy of their opponent's pieces.

Thermodynamics

The laws of thermodynamics can also be applied to chess. For example, the concept of entropy can be used to analyze the probability of a particular sequence of moves occurring. This can help players make decisions about which moves are more likely to lead to victory.

Quantum Mechanics

Quantum mechanics, the branch of physics that studies the behavior of subatomic particles, has also been applied to chess. Some players have suggested that quantum effects, such as superposition, can be used to explain certain phenomena that occur in chess games, such as the "knight's tour." However, there is no scientific evidence to support these claims.

Overall, physics is related to chess in a number of ways. From the basic laws of motion to the complex concepts of quantum mechanics, physics can provide a framework for understanding and analyzing the game of chess.
