Beat Deccan Chargers and secure a place in the semifinals with a total of 16 points.
If Kolkata Knight Riders beat Rajasthan Royals (who would then be at 13 points) and Chennai Super Kings beat Kings XI Punjab (who would then be at 14 points), Royal Challengers Bangalore can afford to lose the game but with a net run rate better than that of Kings XI Punjab.
Bottom-Line: Win the virtual knock-out against Deccan Chargers and get to play the semifinal!
