Doyle-Maybe back in the day he was really aggro and gambly. But nowadays he's just a nit
Negreanu-Pretty loose and aggressive. He's excellent at reading people and therefore willing to play many
hands because of his postflop play.
Harrington-A rock. Very very situational and is capable of adapting very quickly to anything. Very solid play both practically and theoretically
Hansen-Same as Negreanu, but he's more aggressive and doesn't call as often
Ferguson-Same as Harrington it seems
