Was this considered bad sportsmanship?
So I was playing a game of chess with a good friend of mine who I’ve known for years. Part of our dynamic is that we do tease each other here and there, but it’s all friendly, just guys being guys. We were playing chess, and I forfeited the match about 3 moves away from a checkmate. He got annoyed and claimed it was bad sportsmanship even though I politely pointed out that I was bested. Now I was upset that I lost, but I was not trying to prevent the win. If anything, I view it as the same thing as winning normally because I’ve made the decision to throw in the towel. He said that I was trying to spite him and that grandmasters usually quit early on when they know that they have faced defeat, and he said I had plenty of time to forfeit but choosing to do it then shows bad sportsmanship and pettiness. He had won the two previous games we played, and I had asked for my time on this match to which he had reluctantly agreed. After the match, he then made fun of me for losing and claimed I was just mad that I lost. We debated for a bit about it. I claimed he was just saying this because he didn’t checkmate me and conclusively win the way he wanted. He then just kept mocking me, and was showing the match to a friend of his to make fun of me (we were on the phone)
I guess my question is whether or not it was bad sportsmanship, and what I can do to avoid this situation in the future. How do I let the person know that I respect them and their skill after losing, while still maintaining self respect, when the person is better and is more than happy to remind you that they are?
