$2/$100 spread.

Villain ($600) Mid twenties, hoodie, mentioned he was a graduate student. Seems to keep pots small unless he has a monster. Competent, thinking, TAG player.

Hero ($350): 3 limpers and hero completes in the SB with J7

Villain checks in BB.

Pot ($10)
Flop 753
Hero check, SB bet 8, folds around to Hero call

Pot ($26)
Turn 9
Hero check, SB bet $16

From this player's profile I doubt he leads out of the blinds without a strong hand. I think I should have just folded the flop since he probably wouldn't bluff a limped pot here and his value range has me crushed.

Now that I've picked up a flush draw I don't think I'm folding. If I just call do I lead out when I make my flush? or try and x/r ? Can I raise this flop looking to get him off better 7's and possibly over pairs? If I raise, get called, and then miss I think I have to fire the river since from his perspective my likely hands are 68 or 79.

Ideally you fold this pre. I just don't get completing SB with hands like this? It will cost you way too much in the long run.

Bet the flop or fold to his bet!

As played, just call the turn, I guess. I probably check/call the river if I hit because continuing against aggression from this guy is a bad idea, and I'd hate to get there and have to fold.

I am getting 9:1 preflop. At these stakes I doubt a call can be too egregious. If I make my hand on the river I am playing for stacks and never folding. I can't imagine him having two better spades here ever.

If I call turn and hit the river I'm either leading out or x/r. I lean towards x/r since the 3rd spade isn't really a scare card and his hand is pretty value heavy.

A fold on the flop might be the best play. I'm not leading out here. Although it gives me the initiative, I'm still OOP with a moderate hand in a limped pot.

So, he's a competent, thinking TAG player who only puts money in with big hands and you think he's going to pay you off with worse or bet into a flush on the river w/o one?

Egregious is a good word, and completing might not be too egregious, but it is egregious

Yes. Look at things from his perspective. What hands x/c this flop with 2 spades? 7x spades and 6x spades. If he has a hand like 2 pair or better I don't think he will check back when BD spades hit.

Just putting myself in his shoes depending on which spade hits the river I would probably bet two pair + (not bottom 2), maybe that's too aggressive for the blinds though.

Obvious complete, particularly since what you say about this player makes it sound like he's ~never raising in the BB.

Flop, check and call a bet from most players, but against this guy just fold. In these multiway hands out of the blinds, you have to proceed with a lot of caution. Keep the pot small and don't get involved if the situation feels sketchy.

Oh and as played, OTT, checkraising feels suicidal. Call, and I would go for the checkraise if the flush comes as long as it doesn't make the board super coordinated, like if the river came the 8s, I'd lead, but Ks I'd check.

Then your read of V is off. What on earth can he put you on when you flat the turn except a flush draw? Seriously, are you flatting the turn (after flatting flop) with a straight? Top two? Set? This is blind v blind. Unless he's an idiot, he's checking back all spade rivers. What would he gain from betting two pair, a straight, or a set on a spade river?
