Hero with AKo in SB, V on OTB, 3bet pot

Theoretical hand. People gave me responses to my same post on the live strat forum. What do theory people think about this spot?

1/2. Effective stacks 250. No read on V. Rake promo 6+3 up to 60.

Limp. V OTB bets 10. Hero 40 with AcKd. Limper folds. V calls.

Flop (74): 489r

Hero?

The pros in live strat forum say two options:

Check/fold
Bet and plan to barrel all streets.

What do you think?
