$200+15 sng, flop a set on level 1

[Crosby]

Adanthar, would you mind elaborating on what the minreraise accomplishes in the hand? You mention that you are seeking to avoid a showdown but I don't see how the minreraise accomplishes that. The button is simply not folding. Does the BB fold enough additional hands for an extra 125 that you want him to fold? Do you mean that you can buy a cheap showdown this way? That makes sense to me since you're likely either way ahead or way behind, and you may have outs if behind, but I don't really see how the minreraise accomplishes that when you're going to throw out a blocking bet or fold anyway.

I feel like I have to be missing something here. I don't minreraise as much as a lot of my opponents, so I'm hoping you could shed some light onto the value of the play here.
