Value members

Concrete methods

Extension method from dicechess.engine.domain

Applies a MicroMove (turn-based) to the current game state.

Handles piece movement, captures, and basic bitboard updates. This is a raw move application — higher-level logic such as switching turns after three micro-moves is the responsibility of the Turn manager.

The half-move clock is reset to 0 on pawn moves and captures; otherwise it is increased by 1.

Value parameters

mv: the micro-move to apply
