Anti-Sicilian - 2.Nf3 d6 3.d4 cxd4 4.Qxd4

In his first opening database for Modern Chess, the Indian GM Sundar Shyam suggests a very interesting antidote to the Sicilian. After 1.e4 c5 2.Nf3 d6 3.d4 cxd4, he goes for 4.Qxd4!? Of course, at first sight, this move seems a little bit strange. White starts playing with the queen as early as move 4. It turns out, however, that Black doesn't have an efficient way to make use of this concession. Moreover, with his last move, White creates the positional threat of c2-c4, obtaining the so-called Maroczy Bind or the Hedgehog.
