Thx for your thoughts.devwil, especially on the need of aggression in his spot.

You say: "Against a microstakes unknown, I think you generally just want to keep the pot small(er) with a strong non-nut hand like this and get to showdown."

I think from the Turn on I exactly did this. However the pot may had been smaller if Hero checks the flop, as there is a fair chance Villain checks behind the flop.

The clearest mistake is probably to raise this marginal hand preflop.out of position.

Villain showed As Jd 9d 6s

thiagohuang, you wrote: "How often at least 1 player match hand range AA? (given that you have this hand) And the answer is: 33.2%"

in this case Hero didn't have AAxx. So shouldn't the percentage be significantly higher than 33,2 % ??*

Thx for your views and your aspect of the dry board, which minimizes the probability of villain raising a pure draw in this spot.

Thx.
I think you are basically right, although my small cbet could induce more bluffs/semi-bluffs with fold equity than a cbet in potsize for example.
I would add to your last sentence that any player strongly tends to raise a monster draw in a multi way pot..
