Timeout + insufficient material

Hi, I had never heard of the insufficient material rule, but it came up in my last game.  I looked it up, and I don't understand how it applies to the game I played.  

It really seems to me like a slam-dunk black victory if I hadn't danced around long enough to waste his last few precious seconds.  I expected a regular timeout draw.

You were white and your opponent was the one who ran out of time.

You had only a king. Kings can't mate other kings by themselves. Therefore, you have insufficient mating material.

So even though your opponent ran out of time, a draw is declared.

 Don't know if this helps, but here's a previous discussion of the rule (there are many if you want to do a forum search).

No, I was playing white.

I looked at that thread just now, actually.  But I'm wondering how the rule applies to my recent game, where my opponent had a Queen and a Rook on the board.  That's... sufficient.

Yes, I noticed that and was fixing my comments when you replied.

Ok thanks, I understand.
