Scenario: I've been playing on Full Tilt from around midnight to 2am a lot recently. The tables are a little crazier but there is still a balance of a couple of nits/set miners, some decent to good players, maybe a station, and a maniac/overly aggressive player or two at each table. Now when I first sit down, I don't know which is which and somehow it seems lately that I'm catching trips (not a set) right off the bat a lot and everytime I'm overly aggressive, either my opponent folds or I get caught against a boat. Now I wonder if I'm playing them too weak, but it kind of seems to be working out better.

Example:
I'm in MP ($49.50), 1st orbit, w/ [Kh]. I open-raise and the button ($42.15) calls, so does the BB ($7.95).

[9s][4c] Pot $5.25
Good flop, no draws. They expect me to have AK so I make a medium size c-bet of $3 because I don't mind looking weak. The button bites, but the BB folds.

Pot $11
This looks good, but we have 3 options when you get a caller on this board.
1 - He has an Ace also and if he hasn't hit his kicker, he'll give me his stack anyway.
2 - He flopped a set, in which case I'm losing my stack.
3 - He won't call another bet with a lone pair, but could bluff if I check.

So I check and he bets $6.75. I think about a c/r, but just call for the reasons I just gave.

Pot $24
I check again. He bets $11, I call. He turns over pocket 5's.

Again, this seems to be the way I'm making the most profit lately with trips. If I had gotten aggressive, he would have dumped his hand by the turn. Here I pick up an extra $17 profit.

And as I said, if he had an Ace, it works out the same because he's going to bet anyway and if he has a set he's going to bet too. So I win or lose about the same in those instances, but I also win when he has less too which I don't if I'm the aggressor.

This has become my standard play when I have NO read on the player or table. With stats or a read it's more player dependant. I'll let the aggressive guy bluff, the station call, etc... So, even though it's been working well over a few week span, is it the wrong default for unknowns where the tables on the site in general seem to be aggressive? Ok, let me have it.
