With it being multi-way on the flop I think betting is a better spot. No pair but you kill K and 8 plus you are holding to blockers to AK. So a bet here is favorable IMO.

Honestly I hate the $50 bet on the turn. I think if you are going to pursue here with Jh open ended then perhaps semi-bluff is better for you to bet just under or over half pot. This way top pair really has to think about their position and or Ax holdings.

Honestly I could be completely wrong in my idea...
