Nf3 d6 3. Grandmasters sometimes choose this variation when they wish to avoid theory; for instance, it was played by Garry Kasparov in the online game Kasparov - The World.

Black can block the check with Bd7, Nc6 or The position after Nc6 can also be reached via the Rossolimo Variation after 1. Nf3 Nc6 3. Bb5 d6. Most common is Bd7, when after 4. Nc3 Nf6 7. Nxd4 Bg7 Kasparov noted its novelty. Another possibility for White is 3. The most frequent continuation is Nf6 4.

Be2, when White sometimes plays 3. Nc3, which usually transposes to the Open Sicilian after Nc6 without 3. Bb5 The Rossolimo Variation, 3. Bb5, is a well-respected alternative to 3. It is named after Nicolas Rossolimo, and is related to the Moscow Variation. Bg7, Bd7 a hybrid line that also arises from the Moscow Variation after Nc3 is a common transpositional device for White, who can play 4.

Black sometimes plays Nf6 or Nc3 just to see what Black will do before making up his mind to play d4.

With 3. Nf6, or the French Defense after Nf3, Black has some rarely played options apart from Nc6 and These include: Ways for White to prevent this include 3. Qxd4, although Black can also meet 3.

Bg7 4. The idea is that 3. Nxd4 Nf6 5. Nc3 e5, when Nb5 is prevented, and Black will equalize by playing Bb4 and However, after 3. Nf6 is the Nimzowitsch Variation. Nc3 and now a Nxc3 5. Nxd5 exd5 6. Qxd5 Qb6 Ke2 Rf1 Bc5 Kd1 with sharp play favoring White. Qc7 is the Quinteros Variation.

This used to be thought highly dubious, but has been somewhat rehabilitated by 3. Nf3, White can adopt a number of so-called "anti-Sicilian" lines, including: 2. Lines with 3. Nf3 usually transposes to the Open Sicilian; and 3. White can also keep his options open with 3. Andrew Soltis has dubbed that the "Chameleon System," since White maintains the option of playing a Closed Sicilian with 4.

Two drawbacks are that a the Closed Sicilian lines with an early Nge2 are not very challenging for Black, and b if Black plays Nc6 3. Nge2 g6, 4.

Nc3 first before continuing 3. The modern main line runs 2. Nf3 Bg7. Here White can play the positional 5. Bc4, aiming for a kingside attack.

A less common option is Declining it is possible, but accepting it by After 4. Nxc3, it is doubtful that White has enough compensation for the pawn. However, it can be dangerous for Black if he is unprepared, as there are many traps to look out for. Ne2 the Keres Variation , was a favorite of Paul Keres, and has similar ideas to the Chameleon System discussed under 2.

Nc3 - White can follow up with 3. Nbc3, continuing to defer the choice between the two. However, Black can gain an advantage with accurate play.
