When my time ran out this was the status - opponent had only bare king left. In a recent post called " draw glitch" this is exactly described:
With "a bare king" you never score more than a draw when your opponent runs out of time. I had bishop,queen and couple of pawns. My opponent PDAVISJr offered me a draw but I ignored it and just kept on playing as I've done often on CaissaClassic . I was sure I would a least get draw for this game. Any explanation ? Game's end time is 20.05 UTC (June 12th) .
This is truly worth looking into.

Thanks for this report. I will get this corrected. Until then, if a draw is offered make sure you accept it.
