Limper is a fish and bb is tight reg, i dont have much postflop reads on any of them sadly. Are we trapping expecting flushes and good 9x to bet, or should we raise earlier?

[b]Hero ?

I think raising pre is better limping is fine.
Xr would be standard for me unblocking all weaker FD and getting folds from like AJ AK AT is good if he decides to bet those.
Turn xc is mistake imo. We need to build big pot and he only bet 1/2pot so lot of thinner value bets like Qx that will just check riv and we lose ton of value.
Riv-Range wise makes 0 sense to DB. Guess it's fine with this hand but we missplay turn so we end up in this spot.

You could DB turn he won't bet 9x in MW so it's really good turn for you.

What is thinest villain river valuebet?

We're definitely raising pre ourselves w/ 77, 99 & QQ, so what's our value range if we xr flop, Q9s & 97s? I don't like it since we would be representing hands that are realistically only now in BB's range and not in ours. Correct me if I am wrong but we rarely should LC the 2 pair hands to a 6x iso? Those hands would be in UTG's range as opposed to ours so I would prefer xc otf with my whole continuing range whatever that looks like.

Turn is just weird. I'm not sure what to make of it. If we raise, do we x/jam or raise to $15.50 to set up a logical river jam? I don't mind keeping V's bluffs in by xc since the pot is big enough, V might be incentivized to bluff river. We lose all of those with a turn xr.

Iso is 4BB, Q7s is definitely in our range Q9o we probably would fold that vs iso.
And A2 with nut FD is pretty much value raise.

Yeah you're right, what the heck was I reading?
