Villian is running 16/2/1.6, %0 3bet, %100 fold to 3bet, %67 fold to flop cbet. Running over 1.2k hands

My question is with 16/2 this easily looks like set mining multi tabler here but considering how passive and nitty is this an ok turn card to crank all in with? Ideally against another player who actually has agg up around 3 and a higher pfr% and and actuall 3bet % I could see him having a set of 6's here. This player never 3 bets? Should I slow down here or fistpump and switch over to another table?
