I dont believe it was the right thing to do. Esentially your supposed
to be worried about every player on the table, and according to
who your playing, adjust your game plan. You should keep a keen
eye on that loose player, and usually play a tight game, eventually
youll trap him, but, even though he is in a lot of the hands, you must
analise the game of the other players, cause your objective is to
win as much money as you possibly can, and that money doesnt
come only from that loose player but from every player on that table.
Hope i could help.
