Easy solution, think hard. If you know you lost a game resign it, if your not sure ask your opponent, if neither are sure play through. A good sportsman would not take advantage of the situation by trying to win a game they already lost. I have resigned numerous games that i know i lost, big deal there just games. Instead of going on and on about it just figure it out. Fencer has a few more important things to deal with and we should just be glad we have the chance to play or resign games at all.
