IMO, the call preflop is fine. Its on the flop where your play is questionable. you have around 80k after your call. thats 40 BB's. I dont know how you get less than the BB on the flop, but you did it (what hand would YOU throw away gettin 8-1 on your money). and then how you raised 38 more BB's with any hand is beyond me.
bet out 6k on the flop. He min-raises to 12k. you call to see the turn, or reraise to 30k, then if he calls or reraises you, then your done. and you lose half or less of your stack instead of the whole thing. i would call the minraise, then call a turn bet, or fold if i thought he had a king.
