Fire a round ... or two? JJJ Board.

This hand came up recently.. 7 left, micro tourney, we've played about 15 hands or so together.. I had been pretty tight so far, blinds worth stealing..

Alright I'll stop it there because this is where it gets a little murky.. I have about 205K behind right now, with blinds at 10/20K and moving up to 15/30K very soon.. I win and Im in the thick of things and don't need to get desparate.. Do I fire another shell (All-in) or just concede the hand and see if I hit an ace?

Any objections to the flop bet? I thought it was okay considering he's not calling without a solid pair.. I didn't put him on anything big and think I can bump him off his hand..

my logic was: if he had a small-mid pair, he would have surely bet the flop.. if he had a high pair, he would have raised me pre..
