Attacking with the sicilian kan

Here's an interesting set-up for Black, leading to double edged positions.

You can see Black's preparing to attack white's kingside. This is especially effective as White tends to castle kingside at least 50% of the time against the Sicilian Paulsen/Kan.

Judit Polgar was one of the first to use this set-up

But this was used more recently by J.Xiong 

and also Fabiano Caruana

and Anish Giri
