Do you believe in the value shove?
I find that at the low/micro NL, a straight-forward overbet shove (rather than cold-calls, check-raises and value bets) will often allow you to extract the most money when you have a really good hand. A main reason IMO is opponent out of disbelief. "Overbet must mean bluff. Why would he want to overbet and scare away people with a monster?"
The value shove works best when you suspect or know (e.g. he check-raised you on flop) opponent has good but losing hand i.e. a big pair preflop, or TP / an overpair postflop.
The value shove also prevents one other thing. If an opponent called a wrong sized (but not all-in) bet, outdrew me and still got the rest of my stack, I would likely go on tilt.
Here are some examples, the 1st 6 all AA PFAIs. Look what my opponents called me in some cases:
