The current partnership is formed between these two batsmen, Virat Kohli and Maxwell. These two are the best in the attacking batting Royal Challengers Bangalore team. If they can perform well for a long time then surely Royal Challengers Bangalore team will be able to score 200 plus runs. Virat Kohli has already scored a half-century and if he can last till 20 overs then there is definitely a chance of a century. Meanwhile Maxwell is the best batsman, but unfortunately Maxwell is already out. So far Royal Challenger Bangalore team's run collection is 124 runs for 3 wickets in 14 overs.
You are right that Virat Kohli stayed till the last even he was unbeaten, unfortunately could not score a century due to lack of ball. However, I would like to say that among the Royal Challengers Bangalore team today, only Virat Kohli played well. Like you I also expected a hard-core performance from Glenn Maxwell but he didn't take the team much forward today. And that's why they couldn't touch 200 at the end of the match and I think 183 runs as a target is not impossible for Kolkata Knight Riders. Moreover, if we look at the performance between the two teams last year then Royal Challengers Bangalore did not win once against Kolkata.
Although I haven't seen any changes between the squads of the two teams last year and this year, but I think Kolkata Knight Riders will win today's match considering the higher target, if Andrew Russell gives his strong performance, Kolkata will easily win today.
