The familiar maneuver  from Kasparov.
1. e2e4  1... c7c5  2. g1f3  2... d7d6  3. d2d4  3... c5d4  4. f3d4  4... g8f6  5. b1c3  5... a7a6  6. f1c4 Fischer's  beloved line against the Najdorf has picked up popularity of late. 6... e7e6  7. c1e3  7... b7b5  8. c4b3 The bishop is very active on the a2-g8  diagonal, but the maneuver costs White time, and it often stays on the  road of Black's raging pawns. This is the reason why the English Attack  blossomed at the end of the past century. White wanted to save all the  tempi on maneuvering by just capturing a hypothetically annoying black  knight on c4 in one move with Bf1xc4. 8... f8e7  9. a2a3  9... e8g8  10. d1e2 An  important difference in comparison to the usual English attacks. The queen stays away from the Nc4 tempi, does not obstruct the d-file, and protects  the g4-square as well. 10... c8b7  11. f2f3  11... b8c6  12. e1c1  12... c6a5  13. h2h4  13... a8c8  14. c1b1 Allowing the positional exchange sacrifice. But  unlike the Movsesian-Kasparov game above, Aronian has his bishop on b3,  and this definitely improves his defensive chances on the queenside. 14... c8c3  15. b2c3  15... d8c7  16. g2g4 Aronian was blitzing while Giri was  taking plenty of time on the clock.
