Stacks typically result from a flat scissors or a gunshot overshoot, where the adversary has already closed the range to less than a turnradius as the defender starts the reversal. The desired result is to see forward LOS from the adversary and gain an offensive advantage. Resist the urge to pull toward the adversary, unless necessary to close the range and get inside minimum range for off-boresight ordnance. Any dipping of the wings will lose lift, and generate a faster rate along the ground, which pushes you forward on the 3/9 line. As the adversary floats out front, use a power reduction, dip the nose to employ ordnance, and complete the offensive transition. If the adversary gets behind you, then a transition back to your defense. Otherwise this side-side stack will remain until one aircraft runs out of fuel, a supporting fighter decides the fight, or someone mismanages the aircraft and fall off first and turn the fight into a vertical stack.
