Bowlers try all sort of things to get an advantage, however narrow that may be, over batsmen including being ambidextrous, pausing in the middle of the bowling action etc. Shiva's style too is one of a kind.
The batsman defended the ball with relative ease but umpire Vinod Seshan immediately deemed the delivery to be a "dead ball". Bedi was the epitome of a smooth and technically correct action of a left-arm spinner, and it was only natural that Shiva's 360-degree turn before delivering brought out this reaction from the spin legend: "Weirdo", he wrote in his tweet accompanying the video.
"I use different variations in one-dayers and T20s so I thought of doing the same because the Bengal batsmen were developing a partnership". "The umpires said dead ball, so I asked, "why are you calling it a dead ball?"
"Unless the 360-degree twirl was part of the bowler's run-up for every ball, the umpire may need to consider whether he/she feels that the twirl was done in an attempt to distract the batsman in some way. But when bowlers do something like this it's deemed a dead ball", he concluded. Batsmen always go for the reverse-sweep or the switch-hit against bowlers.
The argument for and against the technique comes with interpretation of the game's law, which states; "Either umpire shall call and signal Dead ball when ... there is an instance of a deliberate attempt to distract under either of Laws 41.4 (Deliberate attempt to distract striker) or 41.5 (Deliberate distraction, deception or obstruction of batsman)".
But former England captain Michael Vaughan posted saying he saw nothing wrong with delivery.
