This is a very good question.

As you play more hands, you get a feel as to how much a hand is worth, what % of flops you'll like, and what you can exploit.

If you look at the stats, J9o is going to produce top pair x amount of times, a good draw, a weak draw, and maybe a combination. Because the pot will be large for only 1 bet, seeing a flop is good here, because we're paying so cheapily.

In the end, thats what it comes down too. Yes, J9o will lose. It will get outdrawn, it will get bruised. But because seeing the flop is so cheap for how big the pot will be, we must do it.

Oh, and trust me, hands like J9o show a profit. J7o though would be a fold for me, J8o would be marginal. As the connectiveness/top pair chances wear down, the hand starts to suck a lot more.
