Definitely depends on the opponent, and my table image to whatever degree.
If I've been overbetting a lot, I'm damn sure going to overbet the nuts.
I'm never betting less than say 2/3 pot here. And hopefully we've built some kind of pot.
I used to push all the time with the nuts, and got more calls than I'd expect. I don't know which is more profitable, but I tend to "value-bet" now...usually a good-sized bet, though.
