I never believed in aerial jousting. It's so ahistorical. If I have the advantage, in either aircraft, energy, or both, I will attack. If I am cornered, I will attack. If a comrade is in need of help, and I have a good percentage of escaping possible probems, I will attack. If 'the field is level', I may attack, I may not. Any other situation, I will extend. I fly a La-7, but that has nothing to do with the principles I fly by.
