All this whining about HO'ing is soooo boring.
The majority of the time I see people moaning about being HO'd, its from an encounter where both planes are turning hard trying to out-maneuver one another. They end up turning into each other, both take the shot, one wins, the other squeals on 200.
I don't see the problem with the above situation. I'd never deliberately engineer it as reduces my odds of winning the encounter to - at best - 50:50, but if it happens (and from time to time it does) I'm damn well going to take the shot rather than wait to be shredded by the other guy.
The other situation that comes up regularly is with b'n'z'ers. Their intended target turns to meet the attack, thus setting up the HO. At this point, both players have to realize they jointly engineered the situation. The attacker has the opportunity to pull out of the attack and set up again. The defending player usually has other (often better) options to defend. If they both press the HO, they have to accept there's a strong possibility of coming out second best i.e. don't moan on 200 when you lose.
EDIT: Forgot to ask: What on earth is 'no risk HO'? 'No imagination HO' I could understand but playing chicken with heavily armed fighter aircraft certainly isn't risk free.
