what's the best line for ATo on a KQ5r flop? for example, we raise UTG and are called by the BTN. flop is KQ5r. lets assume villain is a solid reg

if we cbet, what do we do on non-jack turns?
if we cbet, do we also cbet if the BB comes along (multiway pot)?
is check/folding this flop better than check/calling?

thanks!
