1792. If you inadvertently move one of your adversary's pieces instead of your own, he may compel you to take the piece you have touched, should it be en prise; or to replace it and move your king, or to leave it on the square to which you have moved it, and forego any other move at that time.
1793. Should you capture one of the adverse pieces with another, instead of one of your own, the capture holds good, if your opponent so decides.
1794. If the player takes a piece through a false move, his adversary may compel him to take such piece with one that can lawfully take it, or to move the piece that has been touched, if such move does not expose the king to check, or he may be directed to move his king.
1795. If you take one of your own men, instead of one of your adversary's, you may be compelled to move one of the two pieces touched, at the option of your opponent.
