Stop and go play refers to a situation when you want to go all-in for a hand but you opt to call a pre-flop bet of an opponent instead but still having the intention of pushing on the flop.
When you are short stacked it might be a reasonable move to go all in when an opponent raises in front of you. Of course you need to consider that you have a decent hand.
If you are really short stacked and all your chips will not be enough to for another full size bet in case your opponent raises, then most likely they will have the odds to call and see the cards so they can make the best hand. In this scenario what you can employ is the stop and go play cause most probably you do not have enough chips to convince them to fold their hand when you re-raise.
It will always be more difficult for your opponent to calling what you do on the flop rather than what you do before the flop. This reduces the odds for your opponent and so they will need to think hard if they want to more cards to give them a better hand. Most likely they will not.
