Dec-19-13 | | Ziryab: Was the loss of the h-pawn fatal? I don't think so. Evan after 50. Ra4, Black is not without resources. Perhaps 53...Nc5 was the game losing error? Does White have a clear win if Black does not facilitate the creation of a passed pawn? |

 | | beatgiant: <Ziryab>
Black looks lost at move 53. If not <53...Nc5>, I don't see a way to prevent 54. Ka3, 55. Kb4, and the c-pawn will soon fall. Then White can eventually push c4, c5 and get a passed pawn. |
|
Dec-20-13 | | Ziryab: I found playing the position against the computer that snatching the c-pawn too soon activates Black's bishop. Nonetheless, I did conclude that Black is already lost at move 50. See http://chessskill.blogspot.com/2013... for some discussion. 41...Qa3 seems to be the final decisive error. With 41...Qxb4 42.cxb4 Black has prospects of holding (I think). |

 | | KEG: Tarrasch had begun horribly at Monte Carlo, losing three and drawing one in his first four games. But he then began a come-back and was just over an even score when he scored his first big win in this tournament with a nice victory over the always tough Schlechter. Although not without a few hitches, Tarrasch here displayed the iron logic that had brought him to the top of the chess world before Lasker seized the crown from Steinitz. It is not quite clear to me why Schlechter gave up his h-pawn so easily on move 29, but even from there it was a tough ending. Had Schlechter not mistimed the Queen trade, he just might have held the draw. The final minor-piece ending was fascination.

Believe it or not, this seems to have been a novelty at the time. While 11...Qc7 is most frequently played and while that and 11...cxd4 are normal, the text has had its adherents since 1902 and is entirely sound. 12. Nbd2
Tarrasch here begins the classic Ruy Lopez maneuver of Knight to d2 and then f1 and finally g3. He could have played d5 between here and move 16, he preferred to maintain the tension in the center for this period. 12... Re8
Schlechter also preferred to keep the tension in the center, and abstained from cxd4 from here through move 16. 13. Nf1 h6

This move defined much of the rest of the game. Safe and solid would have been 18...Ng6. But Schlechter here decided not to allow Tarrasch to control the flow of the game. An interesting choice on his part. The position after 18...g5?! was:

Tarrasch decided that 19. Nhf5 was premature. He had another means of preparing his King-side Lopez-style attack. 19... Ng6

Not a piece or pawn had yet been taken and the game had developed slowly, but now Tarrasch's Knight were ready to do battle on the King's wing. What was surprising was that Tarrasch, having prepared all this so slowly and carefully, now allowed some of the sting of his idea to be lost via a distraction on the other wing. |

20... Qb7
I question whether this was more accurate than 20...Bg7, 20...Nf4, or even 20...Reb8, but that all became moot because--for reasons not readily apparent--Tarrasch decided to simplify on the Queen's side before undertaking his attack on the King's side. This made his attacking venture less potent. But all this is theoretical, since--as the game went--the decisive infiltration occurred on the Queen's side notwithstanding Tarrasch's eventual win of the Black h-pawn. 21. axb5
As suggested above, 21. Ng4! with the threat of Nf5 coming would have been much stronger. This diversion of attention is the major flaw in what was otherwise a strategic masterpiece of a game by Tarrasch. 21... axb5
22. RxR RxR
 click for larger viewNow Tarrasch's King-side attack proceeded. My problem with all this is that Schlechter obtained scary-looking counter-play on the Queen-side with the incursion of his Rook. What is remarkable is that, as the game went, Tarrasch pretty much brushed aside Schlechter's play on the a-file. Perhaps he judged that, in the fullness of time, he would be able to handle Schlechter's counter-attack and turn the tables on him on the Queen's wing. If so, that was amazing (and I'm not sure I believe it). Anyway, back to the King's side.
23. Ng4 NxN
24. hxN
 click for larger viewIn what follows, it is wonderful to observe Tarrasch's simultaneous handling of his King-side attack while neutralizing Schlechter's control of the a-file. A classic case of being able to play both sides of the board. Meanwhile, and surprisingly, Schlechter (a first-rate strategist himself for who is often seriously under-rated) seemed to lose the thread of what was happening. Given Schlechter's blunder on move 29, one must wonder whether he was facing time-pressure as the move-30 time control approached. 24... Ra2
Tarrasch obviously knew this was coming. His cool and calm response coupled with the iron logic of his attack was a display of Tarrasch's positional genius. 25. Bc1
25. Qb1 looks indicated, but Tarrasch obviously knew what he was doing. The position was now:
 click for larger view25... Nf4
This move has come in for some over-the-top criticism: "Aimless. The Knight must retreat." (Tournament Book) Perhaps 25...Nf4 was not Black's best, but retreating the Knight would not have placed Schlechter in much better shape than did the text since either 25...Ne7 or 25...Nh8 would be met by 26. Nh5 or 26. Nf5 respectively. Best for Black was perhaps 25...c4 followed by 26...b4. In any case, the text did little to hurt Schlechter's chances. He did have to retreat his Knight to Ng6 after Tarrasch played g3, but only much later did the presence of a White Pawn on g3 prove of assistance to White, and then only after Schlechter's move-29 blunder. 26. Nf5
 click for larger viewThis was still a complex position with all sorts of chances for both sides. But it was beginning here, and then on move 29, that Schlechter lost his usual cool (time pressure?) and made Tarrasch's well-thought out attacking scheme more lethal than it had to be. |

26... c4
Doubtful. It was needlessly committal on the Queen's side while giving Tarrasch an extra tempo on the King's side. Schlechter should probably just have played 26...Ng6 immediately even though this would have been a tacit concession that his prior move (25...Nf4) was not best. If Schlechter wanted to press further on the Queen's side, 26...Qa6 (with an eye to a later Ra1 and maybe thereafter c4) was best. Tarrasch now doubled down on the King's side:
27. g3 Ng6
28. Kg2!
Making room for his Rook.
28... f6
29. Rh1
 click for larger viewHere, for reasons hard to fathom (unless Schlechter was desperately short of time), Schlechter gave up his h-pawn. He could have defended it by either 29...BxN (as suggested by the Tournament Book) or just played 29. Rh7. Tarrasch would still have had serious pressure, but the Black position seems tenable. But for whatever reason, Schlechter now played:
29... Bc8?
Tarrasch accepted the gift:
30. Nxh6+ BxN
31. RxB
 click for larger view<Ziryab> questions whether, despite the loss of the h-pawn, Black is truly lost here. It is hard to say. White's extra pawn was a doubled g-pawn. At the very least, Black can offer a stiff defense for a very long time. <beatgiant> says that Black was lost by move 53. That is certainly true. But a lot was to transpire in this game before Tarrasch had anything approaching a clear win. 31... Qg7
32. Rh1 Nf8

37. b3
This created at least two possibilities for White: (a) an eventual b4; or (b) an upcoming bxc4. Meanwhile, his Rook still stood menacingly on the h-file. 37... Qc7
Allowing his Rook to retreat while keeping Qa5 as a possibility. 38. Qb2
 click for larger viewSchlechter now had to choose between two reasonable plans: (i) retreat his Rook and play defense; or (ii) go all out on the Queen's side with Qa5 and try to keep Tarrasch busy on that wing. As I will discuss in my next post on this game, Schlechter chose the latter option, and then things got wild with both players erring. The final result notwithstanding, I like Schlechter's choice. |

Jul-04-22
 | | KEG: Post IV
38... Qa5
Now Tarrasch faced a choice: (1) lock up the Queen-side with 39. b4; or (2) open up the b-file with 39. bxc4. I'm not sure which option was theoretically best (Stockfish prefers 39. b4 while Fritz thinks the choice is close). 39. bxc4 bxc4
How should Tarrasch now proceed?
 click for larger view40. Rc1?
This can't be right. Tarrasch had several strong (even if not clearly winning) ideas to pursue. e.g. (A) 40. Bb6 (probably best) Qa6 (if 40...Qa3 White can trade Queens and abandon the c-pawn and play to win the complex ending after 41. QxQ RxQ 42. Bc7 Rxc3 43. Bxd6. Alternatively, he could back off a bit in this line with the less committal 42. Rc1; (B) 40. f4 looking either to tie up the King's-side with f5 or go for a wild Bishop sacrifice after 40...Qa3 41. Qd2 Qa6 42. fxe5 dxe5 43. Bxg5 ?! fxB 44. Qxg5+ Qg6 45. Qxe5 Qg7 46. QxQ+ KxQ and try to win the ending with four pawns--one of which is doubled--against a Knight . This latter idea is probably over the top, but it is the sort of craziness that first caught my attention. In any case, Tarrasch's hyper-cautious move can't be right. Suddenly Schlechter seemed poised to save the game. 40... Nd7!
With Nc5 of substantial use in many upcoming variations, this was clearly best. 41. Qb4
Tarrasch probably played 40. Rc1 with this move in mind. But now Schlechter had a simple simplifying line available, the position now being.  click for larger view41... Qa3?
I agree with the final assessment of <Ziryab> that this was the "final decisive error." From this point on, Tarrasch never gave Schlechter a chance. As <Zirjab> has suggested, Black can almost certainly just trade Queens here with a likely draw: e.g., 41...QxQ 42. cxQ and then 42...Ba6 43. Bc2 Ra3 44. Bf2 c3! 45. Be1 Nb6. Wild and crazy, but I don't see how White can win from here. Schlechter's move also resulted in a trade of Queens, but with a big difference...Black's c-pawn remains blocked and White has a dangerous--and almost certainly winning plan--by shifting his attack to the Queen's side: 42. QxQ RxQ
 click for larger viewWhat followed was a breath-taking display of Tarrasch's technique. His idea involved bringing his King to the Queen's side and going after the weaknesses in the Black position. 43. Kf2!
The march of the White King begins. Schlechter undoubtedly saw what was coming, and--in his desperation to find an antidote--faltered on more than one occasion. But this in no way detracts from Tarrasch's superb end-game play in what followed. 43... Rb3
Not a blunder but misguided. Schlechter's idea on penetrating on the b-file was easily brushed aside by Tarrasch. 44. Ke1
 click for larger viewContinuing his relentless attack with his King. A classic example of the adage: The King is a fighting piece in the endgame. |

Jul-05-22

44... Rb2
This created only a temporary inconvenience for Tarrasch, since--while it momentarily held the second rank--it made it unnecessary for Tarrasch to defend his c-pawn. 45. Bc2 Kf7
46. Kd1
Ready now to expand on the Queen's side:
 click for larger view46... Ra2
Implicitly conceding that his adventure on the b-file was misguided. But by now his position was almost certainly beyond repair. 47. Rb1!
 click for larger view47... Ra3
48. Kd2
The White King plays defense before shifting to offense! 48... Ba6
To have even a ghost of a chance, Schlechter would have had to play 48...Ra5 followed by 49...Nc5. Now Tarrasch rolled, although as will be seen the finale was not as simple as it might appear at first glance. 49. Rb4!
An important nuance (although Tarrasch could probably have won anyway). This move freezes the Black Bishop thus preventing the Black Rook from evading the Rook trade Tarrasch envisioned. 49... Ke7
50. Ra4!
Game now over, provided one has the essential technique in the coming minor-piece ending. 50... RxR
51. BxR
 click for larger viewAt first, I thought the win for White now would be a piece of cake--until I tried winning it against my computer. This is indeed a clear win for White, make no mistake. But some serious endgame skill is still required. As will be seen, Tarrasch had plenty of that. 51... Kd8
I see nothing better.
52. Kc2
The King continues its trek to the Queen's side. 52... Kc7
53. Kb2
 click for larger view53... Nc5
Back in 2013, <Ziryab> and <beatgiant> discussed whether this last move by Schlechter was a mistake. The point made by <Ziryab> was that the text allowed Tarrasch to trade Bishop for Knight thus creating a passed (and protected!) d-pawn for himself. This is entirely valid. The problem, however, as <beatgiant> correctly noted, is that absent Nc5 the White King enters the Black side of the board with devastating effect; e.g., 53...Nb6 54. Bc6 Nd7 55. Ka3 Bc8 56. Ba4 Nd7 57. Kb4 Kd8 58. Ka5. Though everything theoretically loses for Black here, Schlechter's move had the virtue of forcing Tarrasch shed his passed d-pawn to achieve his ultimate breakthrough. This portion of the endgame required nuanced play by Tarrasch. Not all that difficult, perhaps, but Tarrasch had to stay on his toes. 54. BxN
One must imagine that Tarrasch had calculated this exchange through to the end. 54... dxB

But his winning procedure is nonetheless convincing and a pleasure to play over. |

The seemingly obvious 59. Bxc4 would have allowed Schlechter to offer robust resistance and it is far from clear to me that White can still win: e.g., 59. Bxc4 Bd7+ 60. Ka3 Kc7 61. Bb3 Bc8 62. c4 Ba6 and White looks stymied to me. But Tarrasch had a way to break the Gordian knot: 59. d6!
Black is now helpless:
 click for larger viewOn further reflection, I see that Tarrasch probably had a simpler way to win: e.g., 59. Bc6 [59. Be8 also works in a similar fashion] Ba6 60. Bd7Kc7 61. Ka5 Bb7 [61...KxB clearly doesn't work] 62. Bc6 Bc8 [62...BxB 63, dxB KxB 64. Ka6 leads to an obviously won King and Pawn ending for White using zugzwang] 63. Kb5 Kd6 64. Kb6 and Black is out of moves. But Tarrasch's method is completely winning, and more aesthetically pleasing than the above tempo method. Returning the actual game (see above diagram):
59... Be6
The most stubborn resistance, but ultimately useless against what Tarrasch had planned. 60. Be8
60. d7 immediately also works.
Have a look at Schlechter's plight after Tarrasch's 60. Be8:  click for larger viewBlack has no move that doesn't allow White to make decisive progress. 60... Bg8
As good or s bad as anything.
61. d7 Kc7

After trying hard, I can't find a win for White, though I can't believe the game isn't a winning one for Black. After 44. BxN dxB White's best line seems to be 45. Rc2, though even then I found winning to be, at the very least, an onerous task. After your 45. Ke2 Bd7 White seems able to make progress with 46. Rc2 and then, if 46...Ba4 as you suggest then I thought that 47. Ra2 forcing 47...RxR+ 48. BxR would win...but oops, Black locks White up tight with 48...Bb5 and there does not seem to be a way to break through. So the critical line must begin with 45. Rc2. White now comes ever so close, but I still can't find a win. e.g., 45...Kf7 46. Ke2 Bd7 47. Kd2 Ra1 48. Rb2 Ke7 49. Bc2 Ba4 50. Rb7 Bd7 and now...what? As of now, I see no answer to your idea beginning with 43...Nc5, and perhaps that is a way for Black to draw. My gut tells me I must be missing something, but at least for now I must congratulate you on finding what looks like a drawing line that everybody had overlooked for 120 years. Good job!

After 43...Nc5 44. Bxc5 dxc5 45. Rc2 Kf7, White can try <46. Ba2>. After that, the line goes similarly to what you posted above, but now with a Black piece tied down to the defense of the c-pawn. It looks to me like Black has too many weak spots to be able to hang on. |

Jul-09-22
 | | KEG: <beatgiant>I see your point, but I still wind up with the same Bishop and pawn ending that I can't seem to find a way to win: e.g., 46. Ba2 Ba6 47. Ke3 Bb5 [that pesky Bishop again] 48. Kd2 Ra4 49. Rb2 Bd7 50. Bb1 Ke7 51. Ra2 [I see nothing better] RxR+ 52. BxR Bb5 and here we are again. Am I missing something?
I am becoming convinced that <nizmo11> has found a drawing line and that my original conclusion that the position before 43...Rb3 was a win for White. Now it appears that 43...Rb3 was the losing move. |

I think after 45.Rc2 Bd7 with idea Ba4 (instead of Kf7) is the most accurate reply.

But Black can answer to 49 Bd1 with Ba4!?
Stockfish claims that the Rook endgame after 50.Bxa4 Rxa4 51. Rb1 is just a draw:

Black plays 51...Ra3 or Ra2 and White King does not have any inroads, and the Rook alone can't accomplish much.

Jul-10-22
 | | KEG: <nizmo11> I am unable to follow your line, since after 43...Nc5 44. BxN dxB 45. Rc2 Bd7 46. Ke2 [your 46. Kd2 is not possible, so I assume you meant 46. Ke2] Kf7 White cannot play 47. Bc2 since that square is occupied by White's Rook. Since you have seen more deeply than I did in this position, I would be grateful for your full line beginning with 43...Nc5. This will also allow me to follow the recent suggestion from <beatgiant>. If I accept that the position displayed in the recent post from <beatgiant> is what was intended, I agree with <beatgiant> that 1. f4 is a far better winning chance than 1. Rb1. But even with this superior variation, Black seems to hold: 1...Ke8 2. fxe5 [the idea of <beatgiant>] fxe5 3. Rb1 Black seems to hold on with 3...Ra3 4. Kd2 Ra2+ 5. Kd1 Ra2+ 6. Kd1 [the only winning try] Rg2 7. Rb8+ Kd7 8. Rb7+ Kd6 9. Rb6+ Kd7 10. Rg6, but now Black draws with 10...Rg1+ 11. Kd2 Rg2+ 12. Ke1 [the only way I see to play for a win] 12...Rxg3 13. Rxg5 Re3+ 14. Kd2 Rxe4 15. Rg6 Rf4 16. Ke3 Rf1 and now Black holds with ease: e.g., 17. Ke4 Re1+ 18. Kf5 [again the only possible way to make progress] Re3 19. g5 Rxc3 20. Rc6 Rc1 [better than Rc2] 21. g6 c3 22. g7 Rg1 23. Rg6 RxR 24. KxR c2 25. g8(Q) c1(Q) and the Queen ending looks drawn. A great try by <beatgiant>, but your drawing line still seems to be valid. |

I agree that f4 is the best try for White, and provides at least good practical chances.
