Vs random reg 100 ~ hands in

Reads: pretty agressive postflop, did c/r turn with draw and bluffed a blank river.

Saw checkback in 3bet pot with k7 on 56J bet 4 turn and checked A

i showdown AK

Pros of making the call:

Maybe the toppest of top of my range

His line doesnt make sense

My range looks capped too pretty weak hands

For not making the call:

Very odd spot to bluff, if he would have bluffed would he bluff the turn?

What is the play?
