Turn: ($21) 2♦ (2 players)
SB checks, Hero ??

River: ($21) Q♠ (2 players)

As played SB checks, Hero ??

The minraise pre was a misclick, but I don't think that influenced anything.

SB is a fairly aggressive player. Over 500 hands he played 35/20/6


My question is mainly, would anyone just fold on flop with only gutshot and two backdoor fds?

OTT: bd flushdraw is a fairly good card, should we double barrel? More importantly, if we semibluff the turn, do we have to bluff the river?

OTR: how do you size a bet? Does anyone just check behind?

cheers guys

I would.

Does this also mean you would have folded pre then?

I mean half the turn cards are decent enough to continue, are they not?

Call is ok pre given

He most likely has overpair with this line. I prefer betting the turn and most rivers if he can fold overpairs
