After f3 players have to rely more on their own judgement rather than repeat 25 moves of, for example, Najdorf theory as the move is not so well covered in opening text as this major opening. In the presnt game it also allows White to set up a Maroczy pawn formation which is a very different, and more positional line, than variations such as the Najdorf or the Sveshnikov Sicilians.} Nc6 ({Modern theory also indicates} 5... e5 6.

Qd3 {for example, in Leventic-Cebalo, CRO-ch Zagreb 2004.
