Never doubt, in A&A like most games you can win psychologically.
An oppononent gets mentally defeated to thepoint they surrender even though there is still a strong chance of winning.
If you quit early you will never know the limit of your own skill.
In fact I’m going to be harsh and say ANYONE who quits after just 3 rounds is not someone I’d ever like to play against because they are basically saying that if things don’t go there way in the beginning then they don’t want to play.
I’ve certainly recovered from the worst starts, once as Japan i failed in almost all attacks and ended up with 2x damaged BB navy and 2 fighter + bomber Airforce by round 3 and still won on the coat tails of a strong German team mate performance.
Nothing worse than players who makes high risk moves that fail with the sure knowledge if the dice goes against them then they can just start again.
