Definitely 2, as the first option can get you banned from poker networks.
From Doyle's Room...
A player shall act only in his own-self interest, and shall make no action for the benefit of another player. The following actions shall be considered collusion, and any player participating in a collusive effort may forfeit all interest in the pot and is subject to ejection from the game and even being barred from the establishment:
16.08 DISCUSSING CARDS IN PLAY.
- Imparting information about one's hand to a player in the pot.
- Advising someone how to play or suggesting a particular betting action.
- Rendering a verbal opinion about a player's holding when he bets.
- Agreeing to check out a hand when a third player is all-in.
- Agreeing to save a certain amount of money with another player if either wins the hand, when there is potential betting remaining for one or both of the players and other players are involved in the pot.
- Encouraging another player to turn his hand over face-up at the showdown so that he has a claim on the pot.
- Soft-play agreements not to bet or raise another player when head's up.
- Refunding money won to a player, such as the last bet.
A player shall not make any statement that could unfairly influence the play of the hand, whether or not the offender is involved in the pot. (IE Two queens flop and a player whispers to the person next to him "I had a Queen" or slaps the table in disgust indicating he had a queen.)
