I'm still learning the game and have only played in one tournament. However, I did end up going 3-1 in that tournament but still finished at #17 overall based on MOV. In all three of my wins, my opponent conceded before the end of round 6 or before the clock had expired. In all three cases, we both added up points destroyed and all three matches ended with a small MOV on my side.
In one case, it was in round 6. I destroyed one of his two ships. He then pointed out that I couldn't catch and damage his other ship in that turn and I agreed so he conceded at that point and we got lunch. In another game though, I destroyed my opponents center piece ship in the first blow of round 5. He then said he had no path to victory so he conceded at that point. We calculated points on ships killed and it resulted in another narrow victory for me.
I don't remember the game state of the other win.
Being my first tournament, I wasn't sure of what to expect and I didn't really understand MOV. However, after going 3-1, I was thinking I was in the top 10. I was disappointed when I came in at #17 because of MOV but was still VERY VERY pleased as I didn't expect to win a single game going into the tournament.
After the tournament, I reread the tournament rules from FFG to understand MOV and noticed the section about conceding:
"Concession: A player concedes the match. All of that player’s ships and squadrons are destroyed. The players determine their scores."
In my round 6 victory, it was obvious that all ships that could be destroyed were destroyed and no more points could be gained, I don't feel it would be sporting to say that his concession sould destroy all ships and squadrons. However, in my 5th round win, there were other ships I could have destroyed to give me a higher MOV.
So, my question is, what is the etiquette involved in conceding?
