J3s HU 22$

the call pre is pretty bad, 3bet or fold this hand, doesnt play good oop.

when regs check back these boards they usually dont fold (as you said). even to your river overbet this type of player will put the pieces together and call. you rep a thin range because you probably wouldnt overbet dry Kx and you dont have 2x in your flatting range. so you are repping purely flushes.

I think you can make this play more profitable vs an ABC mid-stakes reggy type by potting the river, you risk a few less chips and it still represents the same range. Dont make a habbit of trying to bluff regs off SD value, you are just giving them free chips most of the time. the reason why they check back is to bluff catch, therefore, dont bluff.

What should our flatting range be against a guy that is raising 50% HU.
What if 60/70?
50% seems tight but if he is like 65-70 should I be defending some hands like K6o Q6o etc.?
This is always been a strange teritory for me :).

I agree that it wouldnt be very good to bluff on this board when he is trying to blufcatch, but should I always give up, even if he has shown weakness and I have equity in the hand? After all it is a semi bluff OTT + I can represent a heart river as you said as he cannot have those and I would also value bet a spade river this size as well.

.

I would definitely give up on the hand without equity, in this particular spot the turn bet is ok because you have the draw. without a decent draw i would just give up after he checks back flop.

this deep you can only defend a tight-ish range. you should be rejamming a lot of high cards and suited connectors.

Sometimes I would flat a JTo or a K7s instead of rejamming (sometimes I rejam) . I think flatting something like Q7s-Q8s,K4-K7s,T9-JTo, J7-J8s feels ok occasionally. The better play is to 3bet shove because you get a fantastic risk:reward ratio. The more chips you have the wider you can flat. I think J3s is going to be a very marginal flat even 30bbs deep. I would focus on rejamming and keep your flatting range particularly tight, especially against good players.
