There are plenty of spots where you are against someone whose range contains a lot of really strong hands he's afraid to bet so checking it might be best. However, you should be turning good SDV hands into bluffs if they're really nitty and even times when you are probably good but checking it back is bad because he will sometimes win if you check but can almost never call a bet.
these hands are from donkaments but I think they illustrate these points, they are both essentially bluffs
first hand involves bare king play, blockers help. I think I am good quite often (in general his range is weak) but he's going to fold sooo many better hands and hands with equity that it's worth betting. (p.s. I think pre is probably meh)

This hand, SB was very aggro and straightforward and I'm pretty good here but checking it back is a total disaster when his range is so many draws and combo hands like A8xx with clubs or a 7 that "missed" but accidentally have me beat.

In summation, don't make it easy for people to win at SD with marginal hands against you especially if they are OOP and nutcamping wankers.
