Some of the hands I posted were 200NL hands from last Saturday night. There seemed to be a huge number of donkeys on PokerStars that night so I decided to take a shot at 200NL. It went pretty well I might add.
Anyway, all of my open-raises are 4 BB, that's just $4 or $8 depending on what stakes I'm playing.

And yes, I do usually raise suited aces from second position in a 6-max game. PokerTracker tells me I'm making a small profit on them, so I don't see any reason to stop doing it. The only reason I wouldn't raise them would be if I've been really active lately, or if one of the players with position on me is a calling station.

The KT hand is not a standard hand by any stretch (obviously), but this guy was raising a ton of hands on the button, and I'm not just going to let him get away with it. Sometimes the 100NL and 200NL games get kind of aggressive and you need to occasionally take a stand with a weak hand or else you'll get run over. Against this type of player, I pick a spot and re-raise and they almost always fold either pre-flop or on the flop. His initial raise was only 3.5 BB, by the way. This concept isn't very applicable at all at 25NL, because there really aren't any good LAGs there and in general people don't raise pre-flop unless they have a really solid hand. There's no point re-raising these guys unless you have the goods.
