I don't have the whole hand history, but don't think it is germane to the question I want to ask:

The turn card is a Queen, giving me the nut Broadway straight. I also have a draw to the nut flush. I bet pot and the Villain calls. there is about $20 in the pot, and we both have about $15 remaining.

The river card completes my flush. Should I check here, hoping villain might have an under-flush and will bet into me or maybe bet half pot hoping for a call?

bet if you have the nuts because villains will often be in bluff catcher mode with non nuts when flush completes / really sucks if they check back 2nd NF when they are going to be calling any bet

Normally I wouldn't even respond to such a poorly structured OP, but the "first reply" answer is some of the worst I have ever on this forum so felt I had to give a proper response.

The hand vs range match can be broken down into 3 quite distinct categories:

They have a tier1 hand (flush) and will be betting for you given that you repped the straight and the flush came in meaning that they will perceive themselves to have some FE, EV of betting <= EV of checking assuming it's not someone who will bet 1/6th pot with the 2NF and fold to a raise assuming you have to have it 100% of the time. You would have gotten more by betting a size > 1/6th pot and being called.

They have a tier2 hand which is the same broadway straight you had on the turn before you hit your redraw. They will either checkback hoping you dont have a flush (scared money) or bet trying to get you off the same nut straight that you repped on the turn. You lose when he checks back broadway and was planning on still calling a bet despite the flush coming in and you gain when they will bluff with the nut straight or worse here.

They have a tier3 hand so a set or worse and will bluff at it some % of the time, given that you made no mentions of the action on the flop, this seems super unlikely.

In nut straight vs nut straight scenarios in most player pools when you are OOP and the flush comes in you should generally be checking when you hit and betting/shoving when you don't, this is assuming your opponent is the type of player who will always shove nuts + redraw at low SPRs when you wouldn't be able to get away even if cards were face up and you could see that you are getting freerolled.



How not to allow yourself to get freerolled to a chop on texture changing rivers OOP.

you're welcome for the inspiration seaking , it's what i'm here for

@SeaKing can you explain the logic behind the river bet? Do we really think V is flush deficient otr after turn is 3bet? Wouldn't his naked str8's pile allin ott?

He was obviously boat mining

500z is more aggro overall and he probs has reads, doing this play at micros I think won't be that great vs randoms
