No reads, 4th or 5th hand of the game.

This was my game plan on the flop:
1) Shove if no A or K shows up
2) ~80 bet if an overcard came and shut it down if I get called or raised.

So, my questions are:
1) if the flop are all undercards, if shoving 700+ plus chips optimal or try to extract chips by making 1/2-full pot size bet?

2) If an overcard appears on the flop, still go ahead and make an exploratory bet and shutdown or check fold if we don't have any reads?

Thanks.

Open shoving that flop is 100% unnecessary. I would push if reraised after I had bet t130-160 or so.

I would bet around the same if a K flopped. I think for an ace I would shade towards the lower end of a t130 c-bet.
