As mentioned game was abandoned,
I am playing a chess game. Suddenly, a pop up shows that my opp wins-though he didn't checkmate me! I don't resign, reload, disconnect, or anything like that. So why I lost? When I use "Details" to see why I lost, It just say: "White Wins" (I am Black)
Can anyone help me??
