Bug

So, I was playing against a computer and the computer will play until I checkmate him. I had a queen and rook vs his king (lol), but the game ended in a draw after he moved...and said insufficient material...lol

Whatever was happening on the clock, the system declared it a draw based on material. We'll have a look at that game.

Even so, where were you on the clock when the draw was declared?  (I guess it might matter..)

It does matter. If the side with more material runs out of time then the game is declared a draw by insufficient material as the side with only a King has no way of winning.

This game was played so long ago, I forgot the clock situation, but I seem to remember that I was not low on time at that point (I think I would have checked if I ran out of time or not) but I can't be certain about that...

Because the last sequence of moves was a mate by rook and queen vs king, I should have been able to make those move extremely quickly, and so unless I had only like 2 or 3 seconds left by the time I queened, I don't think I would have ran out of time. But again, I can't be sure anymore, it's been too long since this game was played. Sorry.
