Ambidextrous Pieterson and the trouble thereafter!

Recently in an Eng-NZ ODI, England's Kevin Pieterson played a shot that created some arguments in the Cricketing community. At the outset, I was wondering what the ruckus was all about but after carefully giving it some thought, I did see some validity in these arguments.

Kevin Pieterson's swap shot

As Michael Holding points out in his commentary, if the batsman can change his guard at the last minute, the bowler should also be allowed to do so without notifying the umpire who then would notify the batsman. He should be allowed to sneak in from behind the umpire and bowl either a left or right-handed delivery as he chooses. Although not many players are ambidextrous and will be able to do this effectively, the privileges should be the same. However, a counter argument to this could be that the batsman has a split second to react and play his stroke while the bowler has comparatively more time to think and plan his next delivery.

Cricket is changing so much day after day and one never knows what stranger things are yet to come our way!!!
