[mlagoo]

I recently stopped playing poker because law school was too demanding of my time. However, I deposited a few bucks into PokerStars for when I have a few minutes to waste and need to satisfy my poker itch. Anyway, here is the hand:

PokerStars No-Limit Hold'em Tourney, Big Blind is t50 (8 handed) converter

Button (t1480)
SB (t1340)
Hero (t1985)
UTG (t1310)
UTG+1 (t1650)
MP1 (t1505)
MP2 (t1605)
CO (t1235)

Preflop: Hero is BB with A[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/heart.gif[/img].
<font color="#666666">1 fold</font>, UTG+1 calls t50, <font color="#666666">2 folds</font>, CO calls t50, <font color="#666666">1 fold</font>, SB completes, <font color="#CC3333">Hero raises to t175</font>, UTG+1 calls t125, CO calls t125, SB calls t125.

Flop: (t700) 8[img]/images/graemlins/diamond.gif[/img], 4[img]/images/graemlins/spade.gif[/img], 5[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(4 players)</font>

<font color="#CC3333">SB bets t300</font>, Hero folds.

Final Pot: t1800


Standard? Despite this being a low buyin tourney, I just can't think of a hand I'm beating here. Whether he has a set and is suddenly scared because of a flush possibility, or he actually turned his flush, I'm looking pretty bad here. I just can't see someone playing TP this way.

Oh, and I know the preflop raise is a leak. Should've been something like 225-275. I got greedy. =/
