Ok I think the fact that you went and wrote out the ranges etc is great but I here's what I think.
Preflop I'
m going to assume he's flatting with AK and pairs
QQ below. He's a weak
tight pansy and the pot is already large when it gets around to him, he's afraid to
re-raise and have to
stack off pre without
AA/
KK. This is how I think this player would think, given the information we have thus far so I'
m going
to go with it. If he was aggressive at all preflop, we could simply take these out of his
calling range and add them to his 3bet
range.
Ok now, what range of hands is he calling my c-bet with?
Well he could be with a number of hands. Since he's
tight he seems to know at least something about poker - ie: c-betting is common from someone who raised pre but it's also hard to make a hand. So he's likely peeling the
flop with a fairly wide
range relative to the strength of my hand - mostly pairs or any ace of course. He may think his
pair of 8's or 9's are still good and that I will shut down on the
turn if I missed the
flop.
So obviously he'll call a c-bet with hands that have us beat:
AK, 55, 77 (we assume
AA is not in his
range because he would have 3-bet preflop based on our assumption)
However he'll also likely call 1 street with alot of hands that we either chop or are well ahead of:
AT+,88+ (and maybe a
SC for the
straight draw but it's probably somewhat unlikely so I'll just ignore it for simplicity)
I put 88+ which to be honest we
don't really have perfect information on whether he calls with any
pair worse than an ace or not, but if he does - HE IS LIKELY FOLDING THESE HANDS TO A
TURN BARREL - because I'
m repping an Ace or better basically. I
don't think he'll
call down the mid pairs in his
range to the
river that may have called one
street so far. He'll likely shut down as a
turn bet basically sets up stacking off on the
river.
The rest of the hands that he called preflop with will of course
fold to the c-bet based on the assumption that he's not
tricky and floating us with
air, though he could be. So I imagine at least a few combo's of weird stuff could be in his
range by the
turn, though I won't get value from them either if I bet. And if he bet's the
river he may have some of this junk in his betting
range.
Which brings up my point of checking
back the
turn - we want to keep the ENTIRE c-bet
calling range in there till the
river. The board is dry so we can't be too concered about being drawn out on because I'
m assuming he doesn't have much raggy junk in his
range, thus there's no real need to 'protect' or hand. Against OTHER villains betting here is great.
We'll find out if we're beat when we go to v-bet the
river as a C/R is basically never a
bluff here. So if we bet the
turn we basically commit ourselves on the
river and likely will not get called for stacks unless we are beat - thus the reason for
pot control. My assumption is this player will not
stack off with a worse hand often enough to make trying to get it in profitable, so why are we setting up a
river shove when it's likely -EV?
Now I've checked the turn, and in doing so, I've under-repped my hand so I can attempt to get value from many hands in his range that would shut down to a turn barrel, but may call a river bet after sensing weakness from my turn check. He may take
Ax completely out of MY
range, so he may think whatever
pair lower than an ace that he called one
street with is good - thus more combo's for me to get value out of with 2 streets of betting, which I would not have accomplished by betting again on the
turn.

This is exactly my point and is even more a reason to not bet the
turn - because he likely isn't continuing to a 2barrel without a narrower
range than his
range he called the first
street with. So if I
check back the
turn, I keep his entire
range he called a bet with on the
flop with on to the
river, where I can expect to exctract value from hands like
TT or
JJ, weaker aces etc - hands that I
felt would not have called a 2-
barrel. 2-barreling is basically setting up committment to
stack off on the
river against a
range that has will have greater
equity than us.
