Its a casino in Southern Indiana. Hollywood in Lawrenceburg. They have 2 or 3 $1-$2 games but they are really nitty. The $1-$3 game is very loose with common UTG straddles and $18 to $25 dollar open raises. Max starting stack of $500 makes for a deeper game that gets good.
As for the hand, I figure if he has 2 pair, set, or weaker flush he is at least calling here. I do play overly aggressive post-flop which usually looks weak when I have monsters. I agree with the 100 bet. Good advice.
