turn is close, i probably just check behind because he has sooo many Ax here, i doubt he's calling 2 barrels with a ton of 9x and def not any PP's below that....I threw together a pretty generous range and the most i could get us equity wise is 45%, i'd check behind.
Note if it was a KQ8cc flop i would like the barrel a lot more because he is going to have less Kx in his range than Ax and he will have a lot more flush draws because the Ace of that suit is not exposed
