When you do not want overcalls

[SlantNGo]

I'm not sure if I've ever applied this concept correctly, but I felt pretty confident that this was a good time for it. No solid read on either of them, but BB looked to be LAG after ~20 hands.

At the flop, I'm ready to concede defeat. Done with the hand. But when both the flop & turn are checked through, with BB betting the river, I thought there was a good chance he was just bluffing, and I think a normal player would be able to lay down a King here for 2 bets.

Would it have just been better to bet the turn?
