In reality, you need to fight in every situation while there's still a chance, especially in tournaments during the playoff stage. I often see reports saying something like, "I lost some of my army and GG." However, it should be noted that the tournament is called "Novichok," so the probability of an opponent making a mistake also exists. I have had situations where I won games even when I didn't have enough resources to build structures. My advice to all beginners: You need to fight! And it's never too late to give up!
It reminded me of the game with Hermit from the fifth installment of Heroes, where both players lost several times, but no one showed it :D
