My Recent Game : Stalemate or Checkmate

After my opponent made a blunder move in the middle game, it gave me the control of game.  To my surprised, the opponent didn't toward the end game.  If I had not paid attention to the end game, the game could have ended up stalemate.  So I was careful with my rook and king & make sure I had the position to win the game.  After a careful analysis, I won the game.
