Live 1/2NL at Sands Bethlehem w/ some pretty deep stacks, playing 7 handed at the time, and a somewhat frequent straddle.

Villain 1 (Button) is pretty tight, 30ish yr old, Marine Corp hat and hoodie, and playing straightforward from what I can see after 2 hrs. Villain 2 (SB) just joined the table and immediately doubled up w/ nut flush vs. a flopped set. Older European, no other reads.

$4 straddle, 2 players fold, Hero opens to $14 w/ 78 ($850 stack)

Button ($600 stack) 3bets to $32, SB calls ($600 stack), BB folds, straddle folds, Hero calls 

Hard not to put Button on a pretty nutted range here given the sizing and I had only seen him 3bet one other hand. Being a total unknown I’m not sure what to make of the flat by the SB. My instinct says he flats w/ pairs that don’t want to 4bet, maybe as high as QQ/KK and hands like AQ/AK, but have certainly seen plenty of 1/2 players call here with anything they would have called a standard raise with like suited connectors and weaker aces (esp after just amassing a 2x stack)

Flop: 3 5 6 (pot $97 after rake)

Obv one of the better flops I could hope for w/ SD and backdoor FD, but think villains’ ranges are heavily weighted towards overpairs

SB donks for $60

This is a very strong line leading into the PFR and 3-bettor, but still think I’m likely up against one pair like TT-KK. I rule out folding (should I ???) and feel pretty stuck here knowing the button could easily come over the top. I end up just calling and the button calls as well.

Turn: K (pot $277 and $500 left in eff stack)

SB leads again for $100.

I pick up more equity here w/ the backdoor FD, but still don’t think raising accomplishes much here and with these stacks there isn’t a room for a raise-fold and would be committing myself to the remaining $500 in the eff stacks. If my flush outs are clean and neither villain has a set, my 15 outs give me about 30% equity. I’m getting a good enough price and after contemplating raising again, I don’t think there’s enough fold equity and decide to call. Button then shoves for remaining $500 and SB goes into the tank and eventually calls. At this point, this basically comes down to the math, needing to call $400 to win $1377 (almost 3.5:1 needing about 22% to call). Worst case scenario is I’m up against a set and my 15 outs become discounted making this pretty close to a break-even call. 

Pot odds set aside, how you would have played this hand different (pre, flop, turn)? Are you ever raising at any point? This hands just seems to amplify how important position is in these type of deep-stacked spots…

Thanks! (will post results later)
