<ul type="square">Here i have probably about 9 outs so i have idea to donk this flop cus:
- if im behind i wanna build pot cus i have good pot equity and wanna clean my pottential outs like J when UTG+1 raise me, also i wanna kick out all KQ hands.
- if im ahead i wanna make value bet with great redraws until river[/list]Turn: (8.7 BB) 4[img]/images/graemlins/diamond.gif[/img] <font color="blue">(3 players)</font>
Hero checks, UTG+2 checks, MP3 checks.

River: (8.7 BB) 5[img]/images/graemlins/spade.gif[/img] <font color="blue">(3 players)</font>
Hero checks, <font color="red">UTG+2 bets</font>, MP3 calls, Hero calls.

<ul type="square">Here i probably should just fold after MP3 overcall, but when all check turn i decide i have to call one cus pot is quite big.[/list]Final Pot: 11.7 BB

Any mistakes in my thinking?
