First of three hands that made me realize yet again how much I suck - Villian is 100% donkey. Should I have put him in here?

I think you played it fun except the preflop raise a bit small

Everyone always says raise more preflop after a hand like this, but if you raise to $2+ in poor position it completely screams AA-QQ, even to the total donks at the table.

I usually raise 4xbb + 1bb for a limper... so in this hand I would go to $1.50....

I would probably bet more on the flop, maybe $5.... because if he is a total donk he will call with a flush draw and if he has a smaller pair he will think you are bluffing and probably raise/call...

I also agree with Yenool. If I've been raising 4-5x all night, even the drunkest dolt at the table is going to know something is amiss if I all of a sudden make it $2.50 to go with 9 guys to act behind me.

WRT SNGNoob's comment - most jackoffs at $25 NL aren't using PT and have no clue what it is. And I feel that I can outplay most $25 NL guys that are taking the game seriously and have PT after the flop anyways, so I'm not worried about it.

I've been experimenting with advice in NLTAP and have stopped making mechanical raises (4x+1, etc.). I raise anywhere from 3-9x now depending on position, how many in, who's in (TAG rounder, fish, etc.), and what I'm holding. I keep it fluid enough so that even a "solid" $25 NL has a hard time figuring out just what it is that I'm doing. Most guys, even the decent ones at this level, aren't paying attention to small fluxes in bet sizes, particulary PF. It's just ABC for them and that's it. Not bad, but not great.

I also think that PFR was too small. I would go by the rule 4BB+1BB for a limper and would add an OOP bonus (if they want to play with me when I am OOP let them pay more) at least 2-3BB and I would make the same raise with TT, AQs, may be T9s if I want to mix it up a bit (though it is mostly for 6max). So here I think a raise of 9BB is justified, make it 2.5$.

Postflop it is ok. Against one caller, who is short I am ready to go AI almost on any flop.
May be even on any flop.

I thought I read in Ed Miller's new book to sometimes tend to raise more when in a blind.
