16...d4! stays ahead. 17.exd4 17.Nxe4? Nxe4 18.Qd3 Ng5-+ 17...Nxd4 17.Nce2 17.Ncxd5± Nxd5 18.Bxf3 18.Qxd5 Qxd5 19.Nxd5 Bc5± 18.Nxd5 Rbd8± 18...exf3 19.Qxd5 19.Nxd5 Rbd8± 19...Qxd5 20.Nxd5 17...Bxg2 18.Nxg2 White should play 18.Kxg2= d4 19.Nxd4 18...Rfd8 18...Ng4! 19.Red1 Rbd8 19.Bxf6! gxf6 20.c3? 20.Nh4= and White has nothing to worry. 20...Qe6? Better is 20...Ne5-+ aiming for ...Nf3+. 21.Nh4 Qh3 21.Nd4 21.Nef4± Qc8 22.Red1 22.Nxd5 Kh8= 21...Nxd4 21...Qd7 22.cxd4± Much less strong is 22.exd4 Rb6 22...Rbc8 22...Rd6± 23.Rac1 23.a4+- 23...Bb6 23...Bb8± was called for. 24.b4 24.Qe2+- 24...Rc4 25.Nf4 25.Qe2 deserves consideration. 25...Qc8 26.Rxc4 26.Qd1 26...bxc4 26...dxc4= 27.Ne2 f5 27.Qe2 27.Ne2 27...Qc6 27...Bc7= keeps the balance. 28.Qh5 28.Qg4+± Kf8 29.Qh5 28...f5?
28...Bc7!= and Black is okay. 29.Qg5+!+- Resist 29.Qxf5?! Bc7± 29...Kh8 29...Kf8± is a better defense. 30.a4 Rg8? Accuracy: White = 21%, Black = 8%. . Loss on time!? 30...Rd6 is a better chance.
