It was played by Firouzja against Radjabov in the first round of last year's Candidates Tournament. Radjabov is on Lei's team so they certainly did a lot of work on this line. 6. e4e5  6... f6d5  7. c3b5  7... d5b6  8. f1e2  8... b8c6  9. e1g1  9... f8e7  10. c1e3  10... e8g8 The game follows the main line of the variation. 11. b5c3  11... a8b8 This is an important position. 12. b2b3  12... c4b3
