Stars nano: QQ from SB, bet the river?

[checkmate36]

PokerStars 0.05/0.10 Hold'em (9 handed) converter

Table was not as loose as some of the tables at this limit. VP$IP was 35% and PFR was at 2%.

MP3's VP$IP was 30% PFR 0.
CO's VP$IP was 60 and PFR was also at 0. These guys were passive but not enough hands for PT to rate them yet. They appear to be calling stations.

Preflop: Hero is SB with Q[img]/images/graemlins/spade.gif[/img], Q[img]/images/graemlins/diamond.gif[/img].
