re: Poker & loose players
there is no such thing as luck, as it was said before. just play your game, maybe be a little more cautious against him. against a loose player, you want to slow play the big hands, as he will likely keep bluffing
trying to steal. just re-raise after the river if you have the nuts or something you believe to be the best hand and he will realize that he cannnot steal from you, and will likely become a bit more cautious, or should anyway. just do not get into betting wars with him, as he wont fold, as you said.
