I could only win a pot this big at InterPoker (low content)

Your post is a fine example of weak-tight thinking.

I've played in many games where it wasn't at all uncommon to go 6 bets on the turn and another 8 on the river, with neither party having the nuts.

If the opponent is a rock, he can safely stop earlier, but if his opponent is a gambler, he should be prepared to play a very large pot.
