Hero (UTG): $50.45
MP: $55.40
CO: $43.85
BTN: $51.70
SB: $76.60
BB: $41.90

Pre-Flop: J[img]/images/graemlins/spade.gif[/img] A[img]/images/graemlins/heart.gif[/img] dealt to Hero (UTG)
Hero raises to $2, MP calls $2, CO raises to $3.50, 3 folds, <font color="red">Hero calls $1.50</font>, MP calls $1.50

I read CO's minreraise as a sign of big strength, putting him on AA KK QQ AK AQ and maybe a few more (JJ?, TT?).

I am not happy with a flatcaller and a reraise behind me, but would you consider folding here AJo 6 handed for an extra $1.50?

Flop: ($11.25) J[img]/images/graemlins/diamond.gif[/img] 6[img]/images/graemlins/heart.gif[/img] 2[img]/images/graemlins/club.gif[/img] (3 Players)
<font color="red">Hero bets $5</font>, MP folds, CO calls $5

I thought I had to bet half pot to find out where I am, and probably fold to a raise. C/R seems too expensive, betting more seemed too dangerous, betting less seemed too weak. Opinions?

Turn: ($21.25) K[img]/images/graemlins/spade.gif[/img] (2 Players)
<font color="red">Hero checks</font>, CO bets $3, <font color="red">Hero calls $3</font>

Bad card for me. I checked with the intention of calling if given the right odds, which I think happened.

River: ($27.25) T[img]/images/graemlins/spade.gif[/img] (2 Players)
<font color="red">Hero checks</font>, CO bets $3, <font color="red">Hero calls $3</font>

Another bad card for me. According to the range I put him on pf, at this point AQ was the only hand I had beaten, and now it makes a straight. Can I possibly do anything different here than c/c the $3 bet?
