BTN - super loose-passive.
SB - has the jesus seat on BTN. History hand: I raised in CO, villain c/raises with top pair, bets turn, and checks low board card that brings in backdoor flush.

I raise black AK UTG. BTN cold-calls, sb calls, BB calls.

Flop: A 5 2 (2 diamonds) Pot~7.8sb

I bet, BTN calls, sb calls, BB folds.

Turn: Q (diamond) Pot~5.9 BB

sb checks, I bet, BTN calls, sb raises, I call, BTN calls.

River: 8 (diamond) Pot~11.9BB

sb bets...

I fold.

nh. id prob call if turn was Kd

Tough spot on the turn, sb check raising you both on the turn screams strength, I would be tempted to fold with no real draw and just one good pair

how smart is sb? it seems not very AND it seems he's super passive. so this seems like a clear fold...BUT it's also super obvious that this is a perfect spot to kr the best hand off of the winner so the 2nd best hand could win against the big spot on the button.

on the river, that's a super easy fold.

I'd fold the turn without a second thought, if I wasn't looking at my cards.

You should consider folding (the turn) since we'd only have top two pair, you can never be too careful.

this is online...

Live its often ok to exploit fold turn. OL, call except against nit.

River is an easy fold. When most villains raise turn, they either beat TP or have a diamond draw. The exceptions are really good players and really dumb ones who barrel river way too much

.., this makes me wonder what bluffs a good player should have on this turn/river. Candidates: (no diamond) JK; Qx; 5x; 33/44; A3/a4; 3x/4x.

A good player can't have most of these hands. Unless you call and UTG raise in sb with KJ so you can peel A25 flop 3 ways.

I was hypothesizing for this exact instance, and but also other 3 card flush boards. In general, I think most people don't have enough non-FD bluffs. So, when a 4th flush card comes, it's easy for opponents to fold TPTK. This seems unideal to me.

Im with you. I was being sarcastic at the suggestion of considering calling the turn with top two and a third player in the hand.

What's so bad about having an ev near (pot) as the small blind in this spot? If they make the mistake of calling too much, that only increases our ev, in some cases to an ev >(pot).

I can see why you'd think it's not ideal for our opponents to make good folds on the river. I used to think the same thing. However, now I believe it's a good result to give them a choice between the two options of folding, which is 0ev assuming that they made it to the river through +ev play, and calling, which will be -ev assuming that all of our turn bluffs are now nut flushes on the river.

So for the spot on the river in the op, the small blinds ev is huge when he bets, perhaps even >(pot) if opponents will make the mistake of making -ev calls on the river. If the small blind has the K 100% of the time after he bets the river, which I think he should, then his opponents should fold 100% of the time and his ev is (pot). This ev will only improve if the op and or the button decide to look him up on the river.

This is also why I think that neither the op nor the button should ever bluff raise this river.

Jesus seat?
