You’re on the right track with your thinking, but there’s room to be a lot more rigorous. You say that Qx is only a small part of his range, but aren’t sets an even smaller apart? When in doubt about how widely you can value bet, there are two ways to approach it:

1. Try to predict your opponent’s strategy. This is the exploitive approach. If you can do that, great. In this case, it would just mean predicting whether and how much he would call with a Q vs how likely he would be to play a set like this (wouldn’t he have some incentive to raise the turn? Or to fold preflop, for that matter?).

2. Consider his incentives. This is the equilibrium approach. He’ll rarely have a hand better than AA, that should be obvious. So the question is how much incentive he has to call with lesser hands. The threat of a bluff is what gives him that incentive. So what bluffs could you have here? How easily could you hold a hand without showdown value that might try to bluff? That tells you whether and how much you can value bet.

Not sure if I see any incentive to raise the turn with sets for V…

There’s always incentive to raise strong hands. That doesn’t necessarily mean it’s the best play, but you’d always like to make the pot larger. His incentive comes primarily from two places:

1. The risk that you have a draw that will either pay off a raise or fold away equity if he raises turn but may not put any more money unless it improves on the river.

2. The risk that you have a good but not great hand that may pay off a turn raise but check behind the river if given the opportunity. You know, like you did 🙂

Like I said, “That doesn’t necessarily mean it’s the best play”. I was responding to you saying you didn’t see any incentive for him to raise sets. The question you’re asking is the right one, but it’s a big one. Have you seen my Getting Paid series? It talks about how to think about which hands in Villain’s range to target and how.
