I flopped the nuts: How do I extract value here?

[NL__Fool]

I recently made the switch from Limit and the biggest leak I have is overvalueing Pairs and 2 pairs etc. 2nd biggest leak I have is extracting value: How would you extract the most value here?

I figured a J was calling this board and gutshots wouldn't have the odds to call a 3/4 pot bet so is pushing and hoping he has a J an ok move here?

It seems everytime I push like this they fold and everytime I bet weak they call and would have paid off more.

Is there a post or sticky? somewhere that explains how to extract the most value?
