O tempora, o mores

丁立人 (Dīng Lìrén) – Alexander Igorevich Grischuk
Candidates Tournament; Berlin, March 23, 2018

Position after 27. ... Kf8-g8

In today’s game 丁立人 (Dīng Lìrén) missed his golden chance to make, even brilliantly, his first goal. Or maybe, who knows, the realpolitik to the chess superpower has induced him not to defy doom. Whatever it is, in the position of the diagram White could already put the last nail in Grischuk’s coffin with 28. Nd8! – which should not be too difficult to see – with the Knight obviously taboo due to Qe2-e8+. Instead, he plays another good move, quite by chance: 28. Nxd5!? Bxd5 29. Nf4!? 丁立人 (Dīng Lìrén) continues playing safely, and again misses his most basic killer moves (29. Nd8! or, perhaps even more mercilessly, 29. Rxd5! Qxd5 30. Nd8! with mate in four moves). 29. ... Nc1 30. Qxh5 Nd3 31. Nxd5 Nf7 32. Qe2? Perhaps it is not wrong in absolute terms, but 32. Nxf6+ gxf6 33. Bxf7+ Qxf7 34. Qg4+ Kh7 35. Qf5+ Kg7 36. Re4 was a much simpler way to win. Now Grischuk’s Knights jump and dance. 32. ... Nfe5 33. Be4 Rh4 34. f4 Rxf4 35. Nxf4 Nxf4 36. Bh7+ Kh8 37. Qe4 Qc6 38. Bd4? A tactical slip that dissipates any advantage. With the obvious 38. Qxf4 Kxh7 39. Bd4 White still retained quite a bit of a winning view. 38. ... Nxh3+? With 38. ... Ned3!∞ Grischuk would have shrugged off any illusions his opponent might have had about the outcome. 39. Kh2 Ng5 40. Qxc6 Rxc6 41. Bc2 Ngf7 42. Bxe5. This seems a very questionable way of insisting to play for the win. What follows is an infinite stillicide towards an inevitable draw by exhaustion. 42. ... Nxe5 43. Rd5 Re6 44.
