once he fires the K turn i think he's ahead a lot more often than most people are giving him credit for. JJ+ is clearly in his range as is the occasional 45/A4 etc. the main thing that no ones mentioned is that the K is def not a blank--one of the most likely type of hands to bluff that flop is KQ/KJ/QJ type hand--tryin to move KRANTZ off ace high/small pair but still with prolly 6 outs if called. and clearly tay is valuebettin any K on turn and river if he does spike it given prior action.

that said i really dont know tay's frequencies enough to know what to do in this spot. i dont think any of your 3 alternatives (fold-call/call-call/fold) are that much better than the rest. i def dont like raising the turn as a bluff as i think he's bet-folding JJ there close to 0%. i'd prolly just yawn and muck it
