Clarifying 'Ball in Hand' Rules

There has been some confusion on what options a player has once they roquet another players ball. I found these rules and they explain the whole situation pretty clearly:

1) Take the two bonus strokes from where the players ball has come to rest.

2) With "ball in hand" place the players ball one mallet head's length away from the other ball in any direction and then take two bonus strokes.

3) With "ball in hand" place the players ball in contact with the struck ball (where it has come to rest) then strike the player's ball so as to send both balls in the desired direction. This is called a croquet shot. The striker then has one bonus stroke remaining.

4) With "ball in hand" place the players ball in contact with the struck ball (where it has come to rest) and placing the player's foot on his own ball so as to render it immobile, strike the player's own ball so as to send the other ball off in the desired direction while the player's ball remains where it is. The player then has one more bonus stroke remaining. If the players ball moves from under the foot there is no penalty and the bonus stroke is taken.
