2/4 TPTK vs. tight player

[buzz_ly]

I have the table image of someone who can't fold. Pretty sure this is super standard but haven't played much NL lately.

I raise AKo, 18/12 cold calls, all else fold.

Flop K92 rainbow. I lead 24, he calls.

Turn 4. I bet 70, he makes it 150, I call.

River Q. I check he shoves for ~$300. I fold.

Fold the turn?
