The International Carrom Federation (ICF) rules make a lot of references to these, for example:
- If a player pockets the C/M of his opponent by an improper stroke, the C/M so pocketed shall be deemed to have been pocketed. The Due shall be taken out for placing by the opponent and the player shall lose his turn.
Or
- If a player pockets the Striker with the C/m of his opponent by a proper stroke, the C/m so pocketed shall be deemed to have been pocketed.
In the Interpretations section, the Laws state:
- “Proper” shall mean in accordance with the Laws, while “Improper” shall mean contrary to the Laws.
However, this is pretty vague in itself. Can someone exactly define what it means to have a proper/improper stroke?
