Making a habit of always checking back middle broadway pairs on such drawy boards like this is pretty exploitable against regs unless you do it with monsters too but then your just losing to much value in general imo .Against an unknown i guess its good.
Are you folding all turn cards execept the jack/ace of diamonds?
Against i guy who 3bets first hand in BB the turn lead is kinda suspicious, if hes dutch or sweedish uknown im prolly calling and soul reading river
