Raise smaller on turn if you think he is on a draw. (2,5x-3x)
Fold when he 3bets because he will never have the draw, he probably thinks you have it. I dont think he ever will 3bet like this with one pair hands. So he surely has a better two pair or any set.


Just because you see people do stupid stuff doesnt mean you have to do the same and loose money as they do!

Checking behind on the flop but raising the turn doesn't make much sense. Just go for three streets of value by betting out from the flop.

When players make these ridiculous size 3 bets it shows they're bad, so I would expect him to have Ax no kicker quite a lot and just call you down hoping that you don't bet every street. There's also the chance he has a spade draw where we only get value on the flop and turn.
