Was I suppose to value bet?

I'm fairly sure that SSH mentions this (or something similiar) in there someplace...

River: (12 BB) 6[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(4 players)</font>
SB checks, Hero checks, MP2 checks, CO checks.

Final Pot: 12 BB

Results in white below: <font color="#FFFFFF">
SB has Qd 7c (two pair, queens and sixes).
Hero has Ks Qc (two pair, queens and sixes).
MP2 has Qs 8c (two pair, queens and sixes).
CO has 8h Ah (one pair, sixes).
Outcome: Hero wins 12 BB. </font>

In hindsight, it was an easy bet but I've seen these guys also turn over two pair often on the river showing no agression. While I wouldn't consider this a large leak in my game, this looks like I could be losing some money in these situations.
