Working on Agression

I've been working on agression, so I've been playing around with 6max where it's supposed to punish the loose and agressive a bit less. To tell the truth, it's an amazingly different experience being the agressor vs being the caller trying to chase the odds. I've found that I push some chips around to get a bit of an image going, then I generally get at least one person who thinks I'm always playing crap cards and will call me with anything. They also often fold and just assume I have the nuts

Anyway, thought I'd post this hand. I bet the flop to get information, since the table was pretty loose / limpy, then it just kept getting better, and ended with the guy bluffing vs my full house

Thats a very nice hand and a nice outcome. Aside from the flop bet the hand plays itself. You bet again on the turn which is important with 2pair because its a hand you need to protect.

What in the hell was he thinking calling your first 2 bets? I can only guess that he was dead set on a river bluff from the beginning.

the first call i dont get but you realize the second call he had a double gut and a good flush draw.
