Hero (BTN - $300) - Been playing pretty tight and solid this session. Winning several small/mid-size pots with and without showdown.

Villain (CO - $280) - Good amount of history with this regular. He is sitting directly to my right and we are friends in the poker room. He respects my play and commended me for checking my TPGK on the turn in an earlier multi-way pot (he was not in the hand) on a paired board. He pays attention and plays relatively tight facing a raise, but will limp pretty wide. Earlier this session he limped in with 46cc from MP and chased a flush draw. The day before, I limped from BTN with J8hh and flopped trips. He check/called me 3 streets with a weaker 8, but didn't show the kicker. He is generally passive, pre flop and post.

Hero has 6Tdd in BTN. Everyone limps to me. I knew it wasn't a great decision, but it looked so pretty to fold for $2 into $16 on the BTN, so I called. Realize this is probably a leak.

Flop: 8d 9d Qd (~$16)

Checks to me. I bet 10. SB minraises to 20. Villain in CO calls. I think for a bit and call.

Turn: Js (~$75)

SB checks, Villain bets ~$80 into the pot. Hero?

SB clearly looks like he's done with the hand. No reads on SB, he is new to the table and looks like a rec player (it is Saturday night). Have not seen him before.

Villain has ~$180 behind, I cover.

Call. Call river unless board pairs or another d comes out. There are a lot of straights, tw0-pair, AdQx, etc in his range, and he's betting big enough that he's trying to deny FD odds, so few overflushes.

Agree w/ Garick. As of right now, Hero has not showed all that much strength: bet 10 on the button after being checked to and then called (not re-raised) the min raise. I would call the turn and river. If checked to on the river w/ no additional diamond and the board not pairing, I would get all in.

Why call? I would shove. If he has a T he's calling now. If a diamond hits the river he's not calling.

Think I let this one go. Is a passive player really betting pot with 2 pr,straight,etc here rather than c/c? You said he limps wide pre too so Id say he has plenty of bigger flushes. And this was a family pot so increases the chance of someone else having a flush.

Unless v is doing that thing where he has a pretty strong hand, not quite the nuts, but if he bets somehow the bad stuff goes away. But this v doesn't sound like he would do that as described

unless i really know something i am not going to lose 140bb with a ten high flush to anyone but a maniac.

i agree with a call on turn. other player seemed to be chasing a 4th street flush and didn't get there. on the turn i call. i feel like he's protecting two pair-str. if you hit your flush, you're ahead a good percentage of the time.

Hero flopped a flush. Flop was all diamonds.

+1. Would AXdd min check raise on flop? Probably not.
K Q and J high diamonds might to see where they are but it would be very unlikely. Rec player will likely just call down instead of check raising.

This was my rationale, and that's what I did.

This is what I was kicking myself about afterwards. Villain had A2dd.

Over ~120 hours of play I have a significant net loss in deepstack all-in situations like this one. I guess the lesson here is that if I had 80bb here it would be a shove, but since we are deep we are seldom getting called by worse, and there is no use playing the hand so fast. Looking back, I think calling the turn and evaluate river makes sense.

Thanks for all the advice.
