AK - fast or slow?

1/3 8 handed

Game is very easy. Most players are FOF post and fairly face up. V2 is unknown but has been a massive station. I tried bluffing turn and bombing river when he checked back flop earlier HU, he called turn with ATo no pair, river A board is like 4-4-J-7-A backdoor flush, he called turn one time for pot and then called pot OTR, he's also been seen bluffing and playing wild. V1 is a straightforward FOF post.

--H has 850$, V1 has 400$, V2 has 1k--

BTN fish straddles, H sees A♦ K♦ and opens to 20 from MP, V1 calls LJ, V2 calls HJ, 3 ways OOP.

Flop 60 - 9♦ 5♣ 2♠

H checks, V1 checks, V2 bets 30, H calls, V1 folds

Turn 120 - 4♦

H checks, V2 checks back

River 120 - T♣

Hero checks?

Would you play this hand faster? I was going to check-raise turn.
