I have never until now started saying anything in the start of the game. Of course if someone starts I will reply. The reasons I do it is that I am not very good at English. So I afraid start a conversation in middle of a game where I will not have the time to think carefully before I write. Also because I feel that way I think there are and others who feel the same way, so I don’t want to interrupt them.
I write to the opponent some times 1-2 turns before the game ends. All the times had to do with: Good fight or I was lucky in one draw (If I won the game but in the middle I wasn’t good) etc.
