OTOH so has the grob. :-)
But still it is a opening with some good points. The position is solid with nothing obviously wrong. You quickly leave the tactical opening traps of the Sicilian, which wharris undoubtably knows very well.
Of course it is not as strong as the traditional variations. Unorthodox openings tend to be unorthodox for a reason. And somehow I doubt that wharris will have trouble with it.
But it isn't a horrible mistake either.
Cheers,
