1/2 NL. Hero just sat down and has $300 eff. Villain is an aggro reg and has about $400.

Hero has 9h 9s in HJ and raises to $10. Villain on BTN 3-bets to $30. Hero calls. Heads up to a flop.

Flop:
10h, 7h, 8c

Hero is quite pleased, lots of equity and I also feel like I probably have the best hand at this point. Hero checks. Villain bets $35. Hero calls.

Turn:
Ah

Now I feel like I'm losing to most of his 3-betting range, but happy to see my equity improve even further. I check again. Villain bets $65. Now I tank a bit.

How should I approach this from here? What mistakes have I made up to this point?

Interesting spot. You can probably lead this flop - favours your range far more than the 3bettor; as played I'm torn between check-call and check-raise. Turn is rather awkward, your flop call should indicate you have something and he's continuing to bet so it seems likely he has at least an Ace. I'm not sure you have sufficient stack depth to check-raise and follow up with a river bomb (unless you think you have immediate fold equity) so I'd probably just call the turn now.

Eh that’s a terrible turn for your hand and great for V’s range. No idea if the heart is good. Probably have 8 good outs and I don’t think you’re getting the odds. Lay this one down

Maybe checkraise flop and shove turn. As played, I think you need to check/call and reevaluate river.

Preflop seems standard. Flop is good for you, and donkbet could be fine since villain 3b range prob won't connect with the flop and may check it back. As played, call seems best.
Turn, we are getting 3:1 but reverse implied odds seem to outweigh implied odds (you don't get paid off by worse as much as you end up paying a better hand when you hit). I think call and fold are close in EV.

I don't know why people are saying lead the flop, but just call as played. I might checkraise the flop with the idea of gii, particularly if his 3! range is not heavily waited toward big pairs.

I think c/r is an option but since villain bets on a board that favors hero, we may take that as a sign that his range is weighted toward tp+, big draws, and excludes some of the weaker stuff like overcards w/ no flush draw or a lower pair.

There is the read this is an aggro reg so maybe c/r but is that with intention to call off a 3b?

After tanking for 30-ish seconds I ended up check-raising all-in for about $250. The guy tanked and was moaning and groaning about it which I thought was a good sign. "Nice acting, I know you have the KQh" etc. But, he ends up calling anyway after about a minute. Amazingly he had pocket 10s for a flopped set. The river bricked out for me.

I did feel like I had some fold equity at the time. Obviously if I knew he had a set I would never have done it, but for hands like AK with no heart for example, I thought the raise could realize some fold equity. But I did question whether or not raising so large was punting money unnecessarily. If I had just called and then folded a bricked river I could've saved $200.

The checkraise on the turn seems pretty bad. I guess maybe trying to get him to fold a better hand, and not be pushed off the best hand on the river. That was about the worst turn card for you, because he could have bet a flush draw on the flop as well as having an ace.

OP was actually 32% gii OTT. Could be drawing dead to a flush. Not sure he bet/folds many hands on the wet board or bet/call with worse much, so the push seems bad.

Tough one.

PRE - against an aggro reg, late-vs-late position, I could see possibly 4B'ing sometimes, but obviously calling is fine.

FLOP - as played, I like a check-raise, but calling is also fine. We'll stack him if the turn is a J and he's got TT-AA.

TURN - with a deeper stack, I could see calling, but if you call off the $65, you'll have put in $130 of $300 starting, and you can't fold. We need to jam or fold turn, I think, and I'd lean towards a jam.

ETA - just read the reveal. Sucks that he flopped top set. Nothing you could have done better here.

Our draws are not to the nuts. But there are a couple important observations about suits.

The Th blocks top set redrawing and Ah ott blocks many of his otherwise superior flushes. So even though our FD sucks at face value it’s actually quite live here vs much of his range. Not sure if QJhh is an unlikely 3! Or KQhh.

Jamming turn to get an Agro off Top pair with redraw or TPGG or KK QQ JJ with a heart seems like it will fold a bunch of his Turn betting range and for the reasons mentioned we should have decent equity when called. I mean here vs this specific hand we had 32% equity when he called with top set and he was tanking.

As a study hand, this is one worth considering how you play the rest of your range as well as villains entire range. Count the combos, calculate the Fold Equity, crunch the numbers.

I’m curious what everyone thinks Villain’s turn betting range is?

If he’s bet folding AK no heart then you are printing. He didn’t want to call with a set lol

V being described as an aggro reg, and on the BTN, playing 1/2, I'd think his pre-flop 3B'ing range could be pretty wide.

On flop - V could have a handful of flopped straights, some sets, some 2P, a bunch of over-pairs, TPTK, TPAK, some un-paired over-cards with some ISSD's or FDFD's (or both), and possible some suited connectors under the board, like 65hh / 65cc.

Turn - I'd think the Ah would slow V down a lot, with a lot of the range that got here. I'd think his turn betting range has to be Ax with a good kicker, at a minimum. I wouldn't expect a competent V to be betting half pot with KK/QQ/JJ, at least not without a heart.

I'd say his turn betting range is AX, over-pairs with a heart, top 2, sets, flopped straights, and turned flushes. Maybe he has a sliver of off-suit broadways with a heart and a straight draw, like QhJx.

You make a good point about the suits. Not sure if this is the point you were making, but on this turn card, V could have a lot of hands that were strong on the flop, but are now beat by our flushes, or he could have some flushes which weren't all that strong pre or on flop.

It sort of splits his range into very strong hands that will never fold, predominantly strong flushes, and some hands that were strong before the turn, but might possibly insta-fold now, which is basically everything else in his range. If we weight his range towards hands that aren't flushes, this is a good turn card to jam.

It's why I like a jam on turn. We can fold out some hands that were strong pre and on flop, but hate this turn card. Even if V calls with a better hand, we still have our straight and flush draws to bail us out, and we can make a set to beat his over-pairs. We're only in really bad shape against his turned flushes with over-cards to the board, which isn't that many hands.

As to your point about how we play the rest of our range - I don't think I'd be continuing without either having a nutted hand, or a hand that is fairly strong as-is, with a reasonably good chance to improve to a very strong hand.
