Ok this hand bothered me a lot today and I still have no clue how to approach this spot
I was at least 6 hours on the waitinglist for this game and was several times offline in between but somehow got to this table.
UTG is a solid reg who opens quite a lot from ep and plays pretty straight forward postflop.
HJ is the fish at this table; unknown but from china :D ; (he somehow managed to get a 20k stack) hes playing like i said for at least 6 hours and most chinese guys like to 3bet pre and dont like to fold to 3- / 4bets; they also like to barrel postflop. this is pretty speculative though, since i only see his country and his sick stacksize.
BTN is in this game for at least 6 hours too. he plays really aggressive and loose play (i havent decided yet if hes too aggro or really good, but definitely annoying to play against)

3bet is pretty std, but i dont know exactly what BTN's coldcallingrange there is (is it like TT+, AQs, and maybe AK to get the fish in, or like every pocketpair and like JTs?) note that hes quite deep against the fish and utg

Ok what are your plans here???? b/f against the regs and stackoff against the fish??? or is the stack to pot ratio to small to find a fold?
