Many players also turn the knight back to b3 and then try to play in English Attack style, with Be3 and the g4-g5 push. But the 7.Nf3 move is more difficult to understand, despite having been played in many games. Praggnanandhaa will make his intentions clearer with his next move.} Qc7 {A thematic move, aimed at avoiding the development of the white bishop on c4.} (7... Be7 8.

I'm always happy when I see new ideas in openings as studied as the Najdorf Defense, as it shows that chess is very much alive. The idea of the knight returning to h2 is perhaps more associated with Ruy Lopez positions. Here the plan is to take the knight to g4 and then to e3, reinforcing control of the d5-square.} (8. g4) (8. Bg5) (8. Bd3) 8... Nbd7 {A novelty.} (8... Be6 9. Be2 Nbd7 10. a4 Be7 11.
