Didnt really have a chance to type up my thoughts in OP as I was on my phone. Basically this is it.
To a random fish, our hand looks very much like AK. This isnt our hand, but it plays exactly the same in this spot (we have AA obv), being that he doesnt have AK ever (imo).
Even though we do block the nuts, there are a few flushes he could have in this spot (ie 1 pair on the flop, donk because hes a fish and must be good, call the turn because we have flush draw, shove river because it looks like I have AK and thats toppest pair toppest kicker.
I just felt that his range is definitely alot better than our hand, even though he can just be spacking off with worse 1 pairs. We also have 40 BBs left if we fold the river.
Really that easy a call based on the fact we have bare

?
