Shove or fold pre-. If you're playing to cash, then fold. You basically have no fold equity since the pot odds
would be such that he should call with any two. You'll also miss the flop 2/3 of the time, and then what are you going to do? Fold? Then why not fold pre- and save yourself the 800? Bluff shove? Then why not shove initially?
Most of the times you do hit the flop, you'll make one pair. Whether you hit the 7 or the T, you'll pretty much have to get it in with your modest pair. Not bad, but certainly not great.
If you're playing to finish high and possibly win, then shove. Yes, there's a good chance you'll bubble. But to finish high with your chip stack, you're going to need some luck anyway so why not go for it against a player whose range is any two cards? Vs. ATC, you're actually a slight favorite, 50.6%. And when you win, you more than double up.
Over the long run, giving up chips by playing tight at the bubble is sub-optimal in terms of how much money you'll win.
