K+R vs K as insufficient material?

I was playing a 2 minute game vs the computer and was valiantly trying to finish winning a simple K+R vs K  mating sequence before I timed out, when the computer suddenly told me "draw -insufficient material". Huh? What am I missing?

Black cannot give checkmate because he has insufficient material. So when you go trough your clock it's a draw and not a win for black.

OK, thanks. That really bakes my noodle but I`ll take your word for it- I can sort of see the intent.

The other alternative is that you lose for running out of time.

BLACK has insufficient material. I assume you time run out. Took me awhile to figure it out as well  :)

Yes, I ran out of time.  When I reflect a bit more, it makes some sense. Ignoring the clock aspect, theabsolute  worst thing I could possibly do in the game is to lose my rook, in which case it`s a draw. So it`s therefore not reasonable to judge the game a loss for me.  It`s just very counter-intuitive.  Next time, if I am playing against a lone king, I know I can safely sit on my duff and not even make a move, and at least get a draw :-)

King+rook vs. King is one of the harder mates for little kids learning chess. We usually have them practice it a few times till they learn it.

LOL. Even though I`m middle-aged, I keep getting stymied for a couple of moves by the mechanics of it, although I am dead certain that I can eventually nail it. But to pull it off in a 2 minute game with the clock running down eludes me most times :-)
