$55 acr mid tourney 10 min blinds

Co (lag, pushes action): 45bb
Btn (solid, not a lot of info): 35bb
Bb (hero, card dead): 21bb

8 handed co raise 2.3bb, btn call, i call bb 97o. Pot approx 8.2 bb with antes
Flop t83r i chk, co chk, btn bet 2.5bb
Pot 10.7bb

Do i take the low variance line, preserve my stack and cc and hope the semi uncapped co does not raise, or do i apply max pressure and jam for a pot worth 50% my stack and push co out and move btn off kjs qjs type hands?

I never know if i should take the high or low variance line.
