No way he gives you credit for being able to resist betting a flush draw or a hand better than his on the turn. If you are unknown to him I think he's going to expect you to bet Ax/sets/2prs/FDs on this turn almost 100% of the time.
This is not at all true IMHO. It is perfectly consistent/reasonable/likely for hero to have checked the turn with a big hand. And the reason for this is
because the turn card is an Ace. For example, if hero flopped a set he would obviously be
planning on betting the turn once he'd whiffed the flop check-raise. But when an
Ace hits the turn he would likely change his plan and go for a delayed check-raise. This is, of course, because the Ace hits villain's perceived range well, and thus it is a card that villain is going to make a delayed cbet on very often. If a complete rag had come on the turn then I agree hero cannot rep very much by 3betting the river, but
on this particular board run out hero can rep all the full houses.
If anyone should not be given credit for being able to resist betting a good hand on this turn card... it is
villain, not hero. Hero can credibly be going for a check-raise on the turn, villain cannot. So, when villain checks back he doesn't get much credit from me for having a strong hand like two pair/a set, nor even usually a FD for that matter (although I concede villain
can have a FD here sometimes).
What this means is that when we get to the river hero's range is still nutted, yet villain's absolutely is not. When this occurs, it does not matter how great a player villain is nor what level he is capable of thinking on ... if he puts himself in a situation where we are able to take a big position against him then there is
nothing he can do about it. Villain is quite entitled to go for thin value with, say, trips Aces by raising our river bet. But once he gets 3bet he should be folding his entire range. No amount of levelling can change the fact that we are nutted here, and there is not a thing he can do about it.
Seriously Dan, put yourself in villain's shoes and imagine you have somehow got to the river with trip Aces. Let's give you ATo. You decide to raise the river donk for value, thinking you are likely to get called by worse cos you have played it weirdly etc. When that big 3bet comes back at you are you seriously telling me you're doing anything other than folding? I think you are folding, and moreover I think that
you should be folding. It is all very well thinking "Wow, I am almost at the top of my range here and my opponent knows I am capped and so could be making a big move on me". But this still does not mean it is a call
if your opponent's range is nutted, and Lil'Dave's range clearly is in this spot.
Edited to say: If villain does not give hero credit for being good enough to check the turn with a set/two pair, then he is
definitely not going to give hero credit for being able to 3bet bluff the river to exploit villain's capped range.
