Quoting: ChiHawk
The rule states nothing about an advantage...that's factually incorrect.
67.1 Handling Puck - A player shall be permitted to stop or “bat” a puck in the air with his open hand, or push it along the ice with his hand, and the play shall not be stopped unless, in the opinion of the Referee, he has deliberately directed the puck to a teammate in any zone other than the defending zone, in which case the play shall be stopped and a face-off conducted (see Rule 79 – Hand Pass). Play will not be stopped for any hand pass by players in their own defending zone.
And here's rule 79 with the same language:
79.1 Hand Pass - A player shall be permitted to stop or “bat” a puck in the
air with his open hand, or push it along the ice with his hand, and the
play shall not be stopped unless, in the opinion of the on-ice officials,
he has directed the puck to a teammate,
or has allowed his team to
gain an advantage, and subsequently possession and control of the
puck is obtained by a player of the offending team, either directly or
deflected off any player or official.
