The best answer?
Don't get into those stalemates to begin with!
That's one reason I don't DA. All the DA is, is an exercise in who can force a stalemate first, or who can barrel roll the best in scissors, or who can dump the most E and bleed all their speed forcing that ONE post-merge, looped, shot.
Don't get into the stalemate, to begin with!
Of course, easier said than done. I guess you could say, don't fly so predictably that the enemy does the same thing as you, and you get trapped. I.E. If you immelman, and he does too, instead of coming back down and degenerating into a stalemate turn fight, try another immelman, or break the opposite way (figure 8 instead of circle) or whatever. These aren't the best examples, but hopefully you get what I'm saying.
