You have a 15 BB stack in the big blind. An aggressive button raises and you hold A♦8♣. Rather than shove pre-flop, you can call and lead any flop.

Short-stacked OOP vs an aggressive raiser with A♦8♣. Which line generates the most fold equity?

WhyCall and stop-and-go. Shoving pre-flop lets him call with two live cards and a price. By calling and then jamming the flop, you make him decide against a board that missed him most of the time - so he folds more often. It's a fold-equity tool for a short stack out of position.
What happensYou call.  Pot: 2,100 (5.25 BB). Heads-up to the flop with ~5,100 behind.

Flop A♥ T♣ 4♦ - you even flopped top pair. Execute the plan?

You're first to act on the flop with your stop-and-go set up. Best?

WhyLead all-in. The stop-and-go shoves the flop regardless - and here you actually flopped top pair, so you have a real hand too. Leading forces him to call your jam into a board that often missed him, maximizing fold equity (with the bonus that you're frequently ahead).
What happensYou jam; he folds a hand that whiffed.  The stop-and-go works.
Instead of a pre-flop shove he'd call with any two, you called and jammed the flop - making him decide against a board that missed him. The stop-and-go converts position and timing into fold equity for a short stack.

The stop-and-go: short and out of position, call pre-flop and lead all-in on the flop - it denies the raiser the easy pre-flop call and adds fold equity.
