It's green because your opponent didn't provide a valid answer or it was submitted late, therefore you automatically get the point. I hope that makes sense.
congratulations- I'm currently tied with my opponents, and things aren't going well.

Yeah, I get that. But does it count for the freebet points? I hope not because that wouldn't be fair to the others. Oh, I see that I have another point for the NBA question. I guess that I can marke this week as a definitive win because I'm 5-0 against famososMuetros.
Cmonn man, cryptofrka wrote about H2H question when free bets are concerned at least 5 times now. You have much better explanation from him in several spots in this thread but here is in short:
H2H questions are looked differently for duel and free bet. For duel you just need to be better than your opponent. For free bet you have to be better than your whole division. Your opponent not posting answers means absolutely nothing when free bet is concerned.
