Usage

There is a piece of new config/state:

halfBlindMove?: HalfBlindMove | number; // half-blind move on the board or number of moves until the next

This state can be controlled by the user in the events.after function, like so:

function afterExample(orig, dest) {
  const move = halfBlindChess.move({ from: orig, to: dest });
  cg.set({
    halfBlindMove: move.halfBlind
      ? move
      : typeof cg.state.halfBlindMove === "number"
        ? cg.state.halfBlindMove - 1
        : 1
  });
  // ...
}

Half-blind pieces are marked with opacity.
