LOL, i've had someone criticise me for taking "HO" shots like this before. Firstly, the name of the game is kill or be killed, and i will never give up a shot to end a fight to appease someone else sense of "fairness". I may choose to give up the shot if i think the bogey has a guns solution on me. E.G. if its a true HO (where we BOTH have a firing solution) then i'll tend to opt out and use that time for a lead turn attempt for the next and impending follow-up turn. I do this not due to any sense of "fairness", but purely from a self-defensive perspective and also from a tactical perspective (lead turn).
If i have a front-quarter high-deflection snapshot opportunity like this, it's simply because my opponent didnt manage to turn more and faster to do it to me. Whether they decided to or were unable to is immaterial. If they decide not to, then thats their choice, but anyone who knows ACM will realise that there is a high chance that by doing a low-g turn, your opponent takes the high-g turn it will lead them getting the snapshot as pictured above - they must realise this and have accepted it as a possibility and taken contengency measures to avoid it (eg getting out-of-plane etc). Its basic ACM, turn harder you win angles, but loose relative E; turn with less Gs you loose angles but gain relative E. If they were simply UNABLE to turn around quickly enough and were actually TRYING too, but just couldnt match opponents turn rate, then they lost the fight fair and square: they were probably the victim of a lead-turn and/or poor speed-control.
I really cant see why people can complain about getting shot down in this fashion. Its not really a pure HO, its a front-quarter snap-shot where only one has the guns solution.
All this BS about 'fairness' and stuff is just that: BS. Why on earth should people fight a contrived and prolonged battle for your opponents 6 when there are plenty of opportunities to end it earlier than that?? And where do you draw the line between a "fair" snapshot and an "unfair" one? 90 deg? 91deg, 85.87989deg AOT?? There's no such thing as "fair" or "unfair" snapshots, just snapshots.
