[lazeeesunday]

Full Tilt No-Limit Hold'em, $0.50 BB (6 handed) Hand History Converter Tool from FlopTurnRiver.com (Format: 2+2 Forums)

Button ($40.45)
SB ($46.40)
BB ($50)
UTG ($34.55)
Hero ($65.10)
CO ($58.75)

Preflop: Hero is MP with K[img]/images/graemlins/diamond.gif[/img], A[img]/images/graemlins/heart.gif[/img].
<font color="#666666">1 fold</font>, <font color="#CC3333">Hero raises to $1.75</font>, CO calls $1.75, Button calls $1.75, SB calls $1.50, <font color="#666666">1 fold</font>.

Flop: ($7.50) T[img]/images/graemlins/spade.gif[/img], 6[img]/images/graemlins/club.gif[/img], K[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(4 players)</font>
SB checks, <font color="#CC3333">Hero bets $6</font>, CO folds, <font color="#CC3333">Button raises to $18</font>, SB folds,

So what's my move? Folding straight up here seems kind of weak tight. Calling and re evaluating on the turn seems a bit trivial as I figure its probably going in on a non club turn and a raise here has some value but the only real option is a shove and that seems a bit much with just TPTK...

No reads on the villain, only sat down ~10 hands ago...

Calling sucks. It's close between shoving and folding, but I lean towards a fold due to the fact that this was a 4-way pot on the flop.

i agree w/ callaway - w/ button raising when you bet into four opponents, fold &gt; shove
