He might be the modern Korchnoi $1 17... b4d2 Anand is following a clear path. 18. d1d2  18... c8b7  19. c6d6  19... e8e6 A nice maneuver. 20. d6a3 It seems So is in control, but ... 20... b7a6 The key move in Anand's strategy $1 He will be able to seize the a-file as well. 21. d3c2  21... a6e2 Once again, a neat, clear path. 22. d2e2  22... e6a6 The pin is more than annoying for White. 23. a3d3  23... d8a5 The impression is that White's position is about to crack at any second, but So finds a nice resource. 24. e5e6 Blocks the e6-square for the knight, thus keeping it away from the queenside. 24... f7e6  25. h1e1 But this is not the optimal follow-up $1 25... a6c6  26. a4c3 Practically, resignation. 26... a5a1  27. c1d2  27... a1b2
