Cover Story / 2014 Sinquefield Cup Best Performance in History?


Many saw Caruana’s result in St. Louis as the best ever for a single classical tournament. Let’s see if that conclusion holds up to objective scrutiny, if there is such a thing. This table does not factor in any ratings inflation and only includes events with at least eight rounds. AVG. RATING

The list doesn't include estimated ratings of historical players, like Emanuel Lasker’s 18/22 in London, 1899 or Alexander Alekhine’s 13/14 in San Remo, 1930. Nor does it factor in combined events like Fischer’s two 6-0 drubbings of Bent Larsen and Mark Taimanov in 1971. Performances like Sofia Polgar’s 81


100-point estimated lead enough to sway all audiences? As with most chess history of this ilk, the debate may never be settled.


Qc8, was much simpler. 42. Bf2 Rxc1!? Consistent, but it was not too late to


return to d7 with the queen. 43. Rxe6 fxe6 44. g4! fxg4?! “I felt that I had complicated the win


quite a lot,” admitted Caruana, “and here I missed his Qd3-e2-d3 maneuver. I completely missed 44. ... Bh4! 45. Bxh4 R8c3—that would have been a nice way to end the game.”


28. … Nf5 29. Bxf5 gxf5 30. f4?! Only now does Nakamura’s drift become


irreversible. Had Nakamura spent more than six seconds on this move he might have realized that the resulting blocked position is awful for him and he should be trying to attack the f5-pawn using a plan such as 30. Ne2 Rh8 (30. ... Qxb5 31. Qc2!) 31. Qd3.


30. ... g4 31. Qd3 Rac8 32. Rc1 Rc4! 33. Ne2


(see diagram top of next column) White’s intended try 33. Qxf5 Nxd4!


leads to an endgame highly favorable for Black.


33. ... Nc7!! 34. Nc3?! Now the pressure builds inexorably.


32 November 2014 | Chess Life


White should have sought solace in a rook ending after 34. Rxc4 dxc4 35. Qxc4 Nxb5 36. a4 Nxd4 (36. ... Nd6!? offers a safe advantage for Black.) 37. Nxd4 Bxd4 38. Qxd4+ Qxd4 39. Bxd4+ Rxd4 40. Re7.


34. ... Rc8 35. h3!?


Desperation, but White could not wait for ... Ne8 and ... Bd8-a5.


35. ... gxh3 36. Kh2 Nxb5 37. Nxb5 Qxb5 38. Kxh3 Qd7 39. Kg2 b5 40. Rb1 a6


The time control has been reached with Caruana a safe pawn ahead and the win should be a matter of technique. However, here for the first time in the tournament, Caruana begins to show some uncertainty.


41. Rbc1 Qe6 41. ... R8c6! intending to follow with ...


45. Qe2 Kf7 46. Qd3! R1c2 47. Qh7+ Ke8 /9 in Rome, 1989 offers differing numbers due to players with low ratings. Is Caruana’s


48. f5? The move 48. Kf1 would have made any


win for Black very difficult, especially given Caruana’s time trouble.
