See here and look for En Passant.

"The last rule about pawns is called “en passant,” which is French basically means “in passing”. If a pawn moves out two squares on its first move, and by doing so lands to the side of an opponent’s pawn (effectively jumping past the other pawn’s ability to capture it), that other pawn has the option of capturing the first pawn as it passes by. This special move must be done immediately after the first pawn has moved past, otherwise the option to capture it is no longer available."

I was going to win this game against computer and it said insufficient material!! Look at the image I have attached and tell me how a queen, a rook and few pawn are insufficient for a lone king!!

Didn't know where to report this error. Guess this is the place. Will someone look at it please?

Cheers.

Kanupartha:

You ran out of time. The computer had insufficient material to mate you. (Just a lone king!) Hence, it was a draw. Consider yourself lucky.

I'd have thought that was pretty obvious. If you could win by running out of time why would you make any moves!?
