But, the burden of memorization is extremely high, and there are a ton of lines you need to know. As such, most people jump around a lot with the white pieces and look to poke and prod in different spots. I would know firsthand—I actually beat the Najdorf twice myself in the recently concluded Prague Masters, but I chose a different line the second time around. It surprises me a little that Hikaru repeated the same variation that he played with Firouzja a few days ago, but you can't argue with success $1 7... f8e7 The main move. 8. h2h3 This has been something of a trend as of late, though it doesn't strike me as that challenging for Black. 8... h7h6  9. f1c4  9... c8e6  10. c4b3 This position is extremely common without h3 and /h6 included, and I don't think their inclusion should change much. 10... b8c6 Probably fine, but might not be totally necessary. 11. f3h4  11... c6a5
