SB checks, Hero ??

i would either check or bet really small

I don't mind value betting or betting small to induce a bluff if I thought villain was capable of turning overpairs into bluffs.

When he calls our turn raise I don't think there are a great deal of 10's in his range apart from J10, Q10 (910 is possible but unlikely obviously) he could also have picked up hearts with AJhh etc

On second thoughts I don't mind checking back either lol.
