SB checks, UTG+1 checks, <font color="CC3333">Hero bets $12</font>, CO calls $12, Button calls $11.65 (All-In), SB folds, UTG+1 folds.

Turn: ($51.65) 7/images/graemlins/heart.gif <font color="blue">(3 players, 1 all-in)</font>

River: ($51.65) K/images/graemlins/diamond.gif <font color="blue">(3 players, 1 all-in)</font>
Hero checks, <font color="CC3333">CO bets $13.5</font>, Hero folds.

Final Pot: $65.15

<font color="green">Pot 2: $0.70, won by CO.</font>
<font color="green">Pot 3: $13.50, returned to CO.</font>

Something about CO's actions made me think monster throughout the hand...anyone do anything differently? Results later.

Your read looks good, however you have to realize that if you choose to play in these games where standard post flop raises are often raises that pot commit you, you have to choose whether or not you are committed to this hand on the flop. You committed over 1/4 of your stack to the pot, and folded to a bet that was less that 1/4 of the pot. This is very bad practice, even with strong reads. You committed on the flop. Call the river bet every time and live with the consequences.

Note your flop bet was too large to be a feeler bet, like I said. Definetly negative EV in the long run to do feeler bets that are over 25% of your stack.
