Everyone who plays chess (at any level) experiences “lose completely by surprise”, because if we weren’t surprised, then we must have seen it coming, and if so, we would not have played the bad move we did! Check out video clips of world championship games and you can see how many games end from a downward spiral in which someone was taken completely by surprise at some point.
I think the hardest part of chess is how to keep going during a game even after being surprised. At some point, chess becomes a battle against your own ego and imperfection, rather than against your opponent. In this way, human chess does not resemble computer chess, since computers have no ego.
