I still strongly disagree with the idea that Daniel Negreanu is loose passive. Loose, sure, but I feel there's confusion about the term passive as it applies to poker. Even if Daniel calls rather than raising more often than many other loose aggressive players, it is often either because he has a read that he's behind but has implied odds
to go for a draw, or because he's setting the player up to pressure him later in the hand. He constantly puts pressure on his opponent, hence aggressive.
A loose passive player is considered loose because he's in a lot of hands, and passive because he rarely raises or bets on his own and will fold when pressure is put on them. This is not a description of Daniel Negreanu.
