KK OOP vs. LAG nightmare flop

[kimchi]

Villain LAG (UTG) is 48/35/4.9 and has been running hot. He recently iso-raised my AKo UTG raise with Q9s from UTG+1 he's be raising all sorts of nonesense (74o) from various positions.

The other guy is unknown, but while waiting for my BB has been cold-calling raises in this very aggressive table. I played 1 hand against him and called and won a river c/r with AQo UI after an obvious straight and FD failed to complete on the river in a large pot.

I hated that flop. Should I have checked and let him (maybe) bluff on the flop? I didn't like the apparently loose guy OTB.

Turn? I didn't want to get bluffed off the best hand - so is a check/call any good here?

The turn check suprised me. Should I have check/called the river to induce a bluff or is getting raised off the potentially best hand after a donk not worth it?

I was praying for an ace-free flop - but my heart sank when I saw that one.
