$5+0.50 Extracting Value with the Nuts

[KPL]

You don't have the nuts, DUCY? [img]/images/graemlins/cool.gif[/img]
I'm usually betting the flop, a king will call, and if neither of them have a king or better, it's hard to extract that many chips in any case. Guess some of the same goes for the river-hard to get any money if he doesn't have a king, but a smaller pair will perhaps call a smaller bet?
