Line with flush draw

PRE - if you think the BTN is raising wide and the SB is calling too much, I think we might consider raising here.

Calling with Q4s doesn't seem terrible, but we'll rarely know when our hand is good, unless we manage to make a boat.

FLOP - I think we can check-raise here, with our specific hand, and barrel on a lot of run-outs. If you're only x/r'ing with 2P+ and high-equity draws, you're not x/r'ing enough.

I like the properties of our hand for a x/r here. We've got a draw to the 3rd nut flush and a BDSD, so we can continue on a lot of turn cards, but if we get 3B, our hand doesn't have so much going for it that we can't find an easy fold.

TURN - As played to this point, I don't like x/r'ing the turn. What are you repping besides 87? Would you raise with 2P or 55? What 2P do you have on the turn that didn't x/r the flop? It would seem to be just 65, and this seems fairly unlikely.

If you are going to make this play, I think your raise should be larger, like $100. You're giving V too good a price to call and evaluate the river, while putting yourself into a spot where you don't know what to do on a lot of run-outs.

RIVER - Interesting spot.

My gut feeling is that our hand is too strong to turn into a bluff, but may not be strong enough to bet for value. And yet, I don't really want to have the river check through and let him see that we raised the turn with Q4s. That's info about our capability I'd prefer he didn't have, at least not without making him pay for it.

I might block bet here, hoping to get a crying call from worse 1P. Maybe $60. That 1/2 pot sizing looks like a bluff when V has a bluff-catcher.

The problem is that we got to the river with only 125 left, and we can't really bet 60 then fold for another 65 if he decides to jam.

As such, I think I might jam for value, targeting all his unbelieving Jx and TT combos that called the turn. It's kind of mergey, because there's a world where better hands might fold to this line. If I was V and had AA or KK, I think I could find a fold if you jammed for just over pot.

Alternatively, I might check, but with the intention of calling a 1/2 pot or smaller bet, something he may do with worse 1P, because it looks like we may have 2P or a set that hates the run-out, and he knows he can't beat those hands at showdown. So he might bet a hand like JT or TT, and occasionally something like 88 or 77 that was a pair plus gutter on the turn.

As a general rule, if you find yourself lost about what to do, odds are good you mis-played an earlier street, if not multiple streets. Consider raising pre, x/r'ing the flop, or check-calling turn.

In a raked game, this is an easy preflop fold...although I could understand 3-betting if your think the button is raising wide but isn't that sticky.

I don't hate preflop closing the action for 2 into 9, but the other options are likely better ... esp. after SB calls (likely very wide). Note that BTN is "allowed" to be wide, he's on the BTN.

Flop I would raise, yes we can have a bunch of draws but BTN can also be very wide at this point. Also we don't want SB to be calling random KT or whatever and take a bunch of our equity. Blocking QJ/QT/KQ also helps, but more importantly there are no nut outs for us and our best card (Ad) either scares them or they also have something big.

Yes, he bet "big" ... but lots of people make that mistake in small pots, so without reads that he doesn't I'd still raise the big bet + call.

Turn I don't like raising now, even though he bet smaller ... and if we played 66/87 this way I'd be raising larger. Yes, you can have 87 but so can he and your hand doesn't block it (or anything). SB is probably weak though, so I kind of understand the idea to squeeze BTN ... just not sure he's folding enough (he's either bad enough to not see the squeeze and is just playing his hand, or can see the squeeze and will call light ... either way not much fold equity).

River is kind of easy, bluffing top pair at 1-1 is terrible so check and see what happens. If he bets big it looks bad for us, but again your hand isn't a good candidate to x/r bluff river (and you don't really have the stack) so fold or call.

You could maybe argue that you are at the bottom of range, but I'm not sure that's true (Td9d/9d8d/9d7d/7d5d/Ad5d are for sure worse) esp. as I'd not have this hand in range.

I don't mind the call from the bb 1800bb deep. Don't mind a 3bet either, depending on how BN tends to defend (if he folds more than he should then 3bet obv).

If BN is betting this flop I expect him to call a xr, unless he hasn't much idea about c-betting.

I don't expect BN to fold often to a small turn xr, especially after SB calls flop. I mean you can just call turn and bluff the K and 8 rivers, perhaps. Would be interested to know your plan on rivers where you don't improve and what you think BN's range looks like after he's called your turn xr.

As played I'd x-consider on river
