Well you can switch legally right to left or vice versa during the bowler's run up. Kevin Pietersen was the first to do it. It was ruled legal by the ICC. So we wasted one of our great weapons years ago and our batsman could really have messed up bowlers, captains and fielders ...... but never did.

Don't know whether an ambidextrous bowler can change hands and disguise which arm he intends to bowl with ......

Has to inform the Umpire before a delivery. I reckon ambidextrous bowling is rare. Left handed batsman can bowl right handed and left handed bowlers can bat right handed. I suppose it's what feel comfortable.

Does he HAVE to, or is it just long-standing etiquette? Is it a rule? Our ambidextrous batsman used to inform the umpire and opposing captain if he changed left to right, but that was in the days when gentlemen were gentlemen and our captain once sent off one of our players for deliberately baulking a player about to catch him out.

Bowlers in the hundred and T20 do everything they can to disguise the delivery. Howell holds it two handed in his run-up, Narine keeps it behind his back. Would it be any more deceiving coming left instead of right arm? And if the batsman can change his stance during the run-up why would it be unfair for the bowler to do so?
