| Mar-18-20 | | rogl: Judging by the speed of his play, Giri was in preparation until 19...b4. Stockfish at depth>40 gives 19...b4, 19...Rxc4 and 19...bxc4 all 0.00, so I don't know why Giri seems to have overlooked this reply. |

| Mar-27-20 | | JohnBoy: I don't get 46.Rg5 at all. I'd snag the e pawn w 46.Re5+ and 46.Rxe4. Then 47.f3 and sit tight. is there a way for black to break in? |
|
Mar-27-20
 | | perfidious: <JohnBoy>, not sure myself: after the continuation 46....Qd5 47.f3 Qxa2+ etc, I would think White would be unable to set up the usual fortress defence seen in these endings, his f-pawn having moved. |

 | | beatgiant: <JohnBoy>,<perfidious>
With the pawn on f3 instead of f2, it's a book (and tablebase) win for Black, because Black has more room to maneuver his king on the first rank. |
|
Mar-27-20
| | perfidious: Which is probably why Giri rejected the obvious idea. |
|
| Mar-27-20 | | eaglewing: How about 33. axb3? Drawing ideas could be to followup with Bc4 being more active than Bb3 or even a followup of Bf5, surrendering pawn b3. With Bishop f5 and Rook on 4th row square e4 is covered twice trying to block the advance e5-e4 (threatening e4-e3), which seems to be essential for Blacks winning ideas. |

 | | Breunor: Where did white go wrong? Score goes higher and lower, but white falls behind with 29 Bxc4: 1) -1.30 (29 ply) 29...Kg7 30.Qb3 Rb8 31.Bxe6 Rxb3 32.Rg4+ Kf8 33.Bxb3 Qc1+ 34.Kg2 Qc6+ 35.Kg1 h6 36.Rg8+ Ke7 37.Rg7+ Kd6 38.Rg6 Qf3 39.Rxh6 e4 40.Rh3 e3 41.fxe3 Qxe3+ 42.Kg2 Qe2+ 43.Kg1 Qf3 44.Bf7 Qe3+ 45.Kg2 Qe2+ 46.Kg1 Qf3 47.Bh5 Qe3+ 48.Kf1 Qc1+ 49.Kf2 Qc5+ 50.Kg2 Qc2+ 51.Kf3 Ke7 52.Ke3 Qc3+ 53.Kf2 Qc5+ 54.Ke2 Qc2+ 55.Kf1 Qf5+ 56.Kg2 Best is Rh4, which is even:
1) -0.08 (25 ply) 29.Rh4 Rc8 30.Kg1 Kh8 31.Bd1 Qg7 32.Bc2 f5 33.a4 e4 34.Qd2 Re8 35.Qf4 Bg8 36.Kg2 Qe5 37.Rh5 Qxf4 38.gxf4 Rf8 39.a5 Rf6 40.a6 Rxa6 41.Rxf5 Rg6+ 42.Kf1 c3 43.Rf8
g5?
Why 46 Rg5?
Stockfish puts the position after Rg5 at -4.9, but the best move, Re5, is -3.9. Why not 53 QxP?
Why not indeed, Stockfish thinks it is best when run at black''s 53, one minute run: 1) -5.97 (61 ply) 53...Qxh4 54.Kf1 Qh1+ 55.Ke2 Qh5+ 56.Ke1 Qc5 57.Re3 Qc4 58.Rh3 Qc1+ 59.Ke2 Kd6 60.Re3 Qc4+ 61.Ke1 Ke5 62.Rh3 Qb4+ 63.Kd1 Qb1+ 64.Ke2 Qc2+ 65.Ke1 Kd4 66.Rg3 Qc1+ (This line goes on, I'll omit the rest).
But when you show it the text move, it gives a slightly better score: 1) -6.22 (59 ply) 54.Re3 Kf6 55.Kg3 Kf5 56.Kg2 Kg4 57.Rg3+ Kxh4 58.Kf1 Qd1+ 59.Kg2 Kh5 60.Re3 Kg5 61.Ra3 Kf4 62.Rh3 Qg4+ 63.Rg3 Qh5 64.Kg1 Qd5 65.Rh3 Qc5 What about 33 axb3?
Text is best:
1) -1.17 (25 ply) 33.Bxb3 Qc1+ 34.Kg2 Qc6+ 35.Kg1 h6 36.Rg8+ Ke7 37.Rg7+ Kd6 38.Rg8 e4 39.Rd8+ Ke7 40.Rd5 Qc3 41.Rf5 e3 42.fxe3 Qxe3+ 43.Kg2 Qe4+ 44.Rf3 f5 45.Kf2 Kf6 46.a4 Kg5 47.Rf4 Qc6 48.Rh4 Qc1 49.Bc4 Qd2+ 50.Kf3 After axb3:
1) -1.17 (25 ply) 33.Bxb3 Qc1+ 34.Kg2 Qc6+ 35.Kg1 h6 36.Rg8+ Ke7 37.Rg7+ Kd6 38.Rg8 e4 39.Rd8+ Ke7 40.Rd5 Qc3 41.Rf5 e3 42.fxe3 Qxe3+ 43.Kg2 Qe4+ 44.Rf3 f5 45.Kf2 Kf6 46.a4 Kg5 47.Rf4 Qc6 48.Rh4 Qc1 49.Bc4 Qd2+ 50.Kf3 |

Your computer analysis above doesn't seem to know book endgames or use a tablebase.Both 46. Rg5 and 53...Qxh4 were explained above. To draw, White needs to set up a fortress with the king on e2, the pawn on f2, and the rook moving back and forth between e3 and g3. 46. Re5+ Kf6 47. Rxe4 Qd5 forces 48. f3, and after 48...Qxa2+ it's a book win for Black. With the pawn on f3 instead of f2, Black has an additional row behind White's fortress and can use it to oust White's king. Still, this might have been a good practical chance because the win takes many moves, and if Black slips up the 50-move rule might apply. 53...Qh4?? allows <54. Kf1> and now Black can't prevent White's king from reaching e2, achieving the fortress and a book draw. |

 | | Peligroso Patzer: <An Englishman: Good Morning: To think, this game from early in the tournament might end up deciding the Candidates.> I was having the same thought this morning.
To elaborate, not only does this game from round one on March 17, 2020, currently (after round 12) give Nepomniachtchi a half-point lead over Giri, in addition, even if Giri gains exactly one-half point on the current leader over the final two rounds, this game could decide tie-breaks. As I understand the tournament regulations, <even in the case of a tie for first place>, three tie-break criteria are applied hierarchically to decide the winner (and only if the players in the tie for first place have identical tie-break results on each of those three criteria would there be a rapid/blitz/Armageddon playoff; see match regulations, section 4.8.4, at: file:///C:/Users/Owner/Downloads/Regulations_for-
_the_FIDE_Candidates_Tournament_2020%20(1).pdf). The first tie-break criterion is: “The results of the games between the players involved in the tie.” (See section 4.8.2. (a).) |

Nepomniachtchi's maneuvering over the last 25 moves was impressive. Fourteen king moves, from e7 to h4 to d4. |
