The Panno Variation. Black plans ...b7-b5.
8. Qd2 Rb8








   
9. Rc1
A popular line. White can play 9. Rb1 with the idea of b2-b4, 9...Bd7 10. b4 e6 11. a4 a5 12. b5 Nb4 13. Nc1 e5 14. dxe5 dxe5 15. Nd3 Nxd3+ 16. Bxd3, with a small edge to White in Khismatullin, D - Gabrielian, A, Kolomna 2016.
9...h5
A rare continuation. The alternative is 9...Bd7.
10. Nd1!?
Other moves: 10. b3 Re8 11. h3 (11. d5) 11...Nh7 12. g3 (12. d5!) 12...e5, Sadler, M - Lewis, A, London 1995, 13. d5!? Na5 14. Bg2 b5 15. cxb5 axb5 16. Nd1, with a small edge to White;
10. h3 Nh7?! (10...e5!? 11. d5 Ne7 12. g4 c6 13. Rg1 b5 14. b3 (14. Ng3) 14...bxc4 15. bxc4 cxd5 (15...c5) 16. cxd5 Bd7 17.

20...Qb8?!
A mistake. 20...Qc7 is stronger, Black continues to defend the a5-pawn, and White has only a small advantage.
