Out of interest is there any reason you're opening 3bb with 16bb? Seems bad to me in general. In this circumstance you should be getting it in and doing so on the flop is just strange.

It's worth looking at flop textures that people might be tempted to make awful folds on and compare this to how much of a mistake it actually is. Most stuff people may find a fold with on flops is stuff you're beating anyway. No one is folding TT for tiny bets on a Q42tt board for example. Boards they may (rarely) find folds on are definitely much stronger for you. I'd imagine people are folding really tiny amounts in both circumstances though if I'm being honest so the mistake probably isn't that big either way.

In a home game you should know the person well enough to know what they do in spots like this. If they're nits it can be an easy fold, if they're any sort of competent you're getting it in pre and just being happy.
