Girl lays down cowboys on river

[Rotating Rabbit]

This is a hand one of my college friends played, which she told me about the next day in lectures.

No reads on Villian, who has just sat down a few orbits back. Hero has the table covered with $800, villian has 650.

Hero is UTG+1, Villian is SB.

Hero has K[img]/images/graemlins/spade.gif[/img] K[img]/images/graemlins/club.gif[/img]
Hero limps, all fold to SB who calls, BB checks.

Flop: 3[img]/images/graemlins/diamond.gif[/img] 4[img]/images/graemlins/club.gif[/img] 8[img]/images/graemlins/heart.gif[/img] (pot = 18)

SB checks, BB checks, Hero bets $18, SB raises to $50, BB folds, Hero calls.

Turn: 4[img]/images/graemlins/spade.gif[/img] (pot = 118)

SB bets $80, Hero raises to $200, SB calls.

River: 5[img]/images/graemlins/club.gif[/img] (pot = 518)

SB bets 400 and is all-in. Hero folds.


So, preflop limp aside, this hand is all about the turn.
