Cricket's Twenty20 World Cup is in full swing, with teams jostling for a semi-final spot in the two groups of the Super 12 stage.AFP Sport takes a look at the five best knocks of the tournament so far:Kohli masterclassHe came, he saw, he conquered. "King Kohli" hit an unbeaten 82 to lead India to a memorable win over arch-rivals Pakistan with more than 90,000 fans in attendance at the MCG.Kohli lifted India from a precarious 31-4 while chasing a target of 160 in their first match, to guide the team home on the last ball in a dramatic final over.His two sixes off Pakistan quick Haris Rauf at the end of the 19th over in the tense chase and a 113-run partnership with Hardik Pandya were the keys to the win, and the knock has already been termed one for the ages.Stoinis blitzHolders Australia were stunned by New Zealand in the tournament opener and stumbled in their chase against Sri Lanka.
Stoinis then walked in to smash an unbeaten 59 off 18 balls in his hometown Perth.The big-hitter demolished the opposition attack with four fours and five sixes to raise the fastest T20 fifty by an Australian in 17 balls, as the hosts won with 21 balls to spare.Skipper Aaron Finch had the best seat in the house at the non-striker's end as he stood with Stoinis in an unbeaten stand of 69, calling it a "special innings".Balbirnie specialGiant-killers Ireland kicked out two-time champions West Indies from the tournament in round one and skipper Andy Balbirnie made sure they toppled one more big gun in England.Balbirnie hammered a 47-ball 62 to guide his team to 157 all out, as he smashed Chris Woakes for two fours and one six in a single over.The knock inspired Ireland's bowlers, who kept England to 105-5 when rain stopped play.
