Pre-flop: (10 players) HERO is BB with Q[img]/images/graemlins/spade.gif[/img] A[img]/images/graemlins/diamond.gif[/img]
UTG folds, <font color="#cc0000">UTG+1 raises</font>, UTG+2 folds, MP1 calls <font color="aaaaaa">(3.5:2)</font>, 5 folds, HERO calls <font color="aaaaaa">(5.5:1)</font>.

I put MP1 on a middle pair or something KQish, probably suited given UTG's standards. PF call weak or standard?

Flop: 6[img]/images/graemlins/diamond.gif[/img] 8[img]/images/graemlins/diamond.gif[/img] 3[img]/images/graemlins/club.gif[/img] (6.5SB, 3 players)
HERO checks, <font color="#cc0000">UTG+1 bets</font>, MP1 calls <font color="aaaaaa">(7.5:1)</font>, <font color="#cc0000">HERO raises</font>, <font color="#cc0000">UTG+1 3-bets</font>, MP1 calls <font color="aaaaaa">(12.5:2)</font>, HERO calls <font color="aaaaaa">(14.5:1)</font>.

MP1's call encouraged me to hand around. I narrowed his range to a flush draw and thus a high card hand I dominated. I tried to represent a monster since I felt confident MP1 wouldn't play back with 2 aggressors.
