After 20 minutes thought, Black replied...

9...Nc5 10.d4 Ncd7 11.b3 c6 12.Ba3!
White is comfortable

12...e4 13.Ne1 d5 14.Bxe7 Qxe7 15.cxd5 Nxd5 16.Nxd5 cxd5 17.f4! Nf6

White intends to create a fortress [ both players thought that Black was better, but after 33.Qe1 White's c-file activity may prove more effective than Black's grip on the g-file.]

33...Rxg3 34.Kxg3 a4? 35.bxa4! Qa6 36.Rb2 Kg7?
[ 36...Qxa4! and White can invade on the white squares]

37.a5! Kf8 38.Rb6! Qxa5 39.Rxb7! Qxa2 40.Rc7
The time control, and White offered a draw

40...Qe2 41.Kh2 h5 42.h4 Ke8 43.Rh7 Qg4 44.Ra7 Qg6 45.Rb7 Kd8 46.Ra7 Kc8 47.Re7
