Intentional suicide - knowing he could not win and I was clearly in the stongest position intentioanlly committed suicide.
- this is very objective. We've had complaints where people get accused for secret diplomacy (or see it as an unfair move) because they didn't attack the alleged strongest player. Then there are reports like this when if someone attacks the alleged strongest player, he gets accused for game throwing or for secret alliance as well.
For this game, I can see on the 19th round, red and green didn't hold a bonus, yellow had Oceania, you had SA and Africa. Green's last move was to break your bonus on Africa. After that, you got to eliminate him when it was your turn. Green's move is reasonable rather than avoid attacking you or just sit and wait to get killed because as you say, he has no chance in winning.
