White has an extra pawn. The position is simplified, and Black has good chances to make a draw in this rook-endgame. The position of Black's Rook is excellent, but Black has problems with one's King.
After possibly making some mistakes, Black managed to make a draw.
The computer program Toga II with white pieces was tactically excellent till the end of the game. However, perhaps it missed some long-term strategic vision in the endgame.
Starting from the present position, Black had 3 minutes of the remaining time.
