| David2009: Friday's puzzle Tarrasch vs Reti, 1922 White 40 ? White continues his mating attack with 40 Kf6 threatening Kf7 and Bg7#. Now
40...Nxd4 loses to 41 Kf7 Rg8 42 Rd8 threatening Bg7#.
40...Rg8 allows Kf7 threatening Rd8. This leaves
40...Kg8 which staves off mate longest: 41 Rg7+ Kh1 42 Rb7 Nd6 43 Rd7 Nc8 (else either the N is lost or mate) 44 Kf7 Rg8 45 Rd8 Nd6+ 46 RxN and mates quickly. Letting White capture the N on d6 is little better. Time to
check:

| bengalcat47: I have seen this endgame study by Troitzky before, where it is given as follows: White has his King on d5, Bishop on h6, and Pawn at g7. Black's King is on f7, and he has Pawns at e7 and h7. The solution is 1 g8=Q+, Kxg8;
2 Ke6, Kh8; 3 Kf7 and mate next move.

| Once: <Fish55: 40. Rb7 followed by Kf6 seems simpler to me than the variation beginning with 40. Kf6, Kg8.> Yeah, me too! You and I seem to be the only ones who went for the pragmatic over the flashy. Straight off, the move 40. Kf6 appeals, with plans of scaring off the black rook and snaffling pawns or setting up mating threats or windmills with the K, R and B combination. But I'm worried about 40...Nxd4. To be sure, mate ends the game but I'm already a pawn down. I need to be sure that the attack will work before throwing another prawn on the barbie with 40. Kf6 But hang on a minute, why not kick the knight away first and then play Kf6? Then we end up with something like this: 40. Rb7 Na3 41. Kf6 Nc4 42. Rd7 Kg8 43. Rg7+ Kh8 44. Re7 Rxe7 45. Kxe7 Kg8
46. Kxe6 Na3 47. Kxd5
click for larger viewTo be sure, it's nowhere near as decisive as "40. Kf6 resigns". But on a Friday night after a hard day at t'mill, it seems to be a darned sight less work to calculate. Mind you, Herr Fritz reckons there are other ways to win from the diagram position. 40. Kf6 is the clear best move (+7.7), but he also likes 40. Bg5 (intending Bf6) and 40. Bg7+ (intending Bf6) - both +1.7 ish after a couple of minutes because black's e and h pawns are falling. 40. Rb7 is around +2. Indeed, just about any sensible move for white seems to get at least one pawns' advantage. So, yes, 40. Kf6 is the star move and kudos to everyone else for spotting it. But <fish55> and I can take heart that our lines also win, albeit a lot more slowly. I suppose there are two schools of thought. One says - "when you see a good move look for a better one". The other says "when you see a good move, play it and leave the brilliancies for the GMs". Oh, and in an endgame, march his majesty as far up the board as you safely can. Because then magic will often happen. |

| turbo231: This is the first time I have solved a friday's puzzle. And it took me only a minute.To me it was easier than a monday's puzzle. That rook did not stand a chance against the white King! |

| CHESSTTCAMPS: In this endgame, white is down a pawn, but has a bishop for a knight in a dominating position. That extra pawn on e6 is backward and of little use to black other than to protect the d and f-pawns. White's king, rook, and knight occupy ideal spots; black's passive army can't keep up. A simple plan for white is evident: oust the black king from the corner, win the h-pawn, and enter with the king to threaten mate and win more pawns. This can not be prevented; the play is really more technical than tactical. 40.Bg7+ Kg8 41.Bf6 and now:
A) 41... Na3 42.Rg7+ Kf8 (Kh8?? 43.Rxg6#) 43.Rxh7 Nc4+ 44.Kf4 Nd6 45.Kg5 Nf7+ 46.Kxg6 wins the N and forces mate quickly A.1) 44... Ra8/b8/c8/d8 45.Rh8+
A.2) 44... Kg8 45.Rg7+ Kf8 46.Kg5! (playing for mate limits black's options) e5 47.Kxg6 exd4 48.Rh7 Ne5+ 49.Bxe5 Rxe5 50.Kf6 Kg8 51.Kxe5 Kxh7 52.Kxd4 with a simple K&P ending. A.1.1) 46... Ne3 47.g3 e5 48.Kxg6 Re6 49.dxe5 (Rh7 Ke8) Ke8 (d4 50.Rd7) 50.h4 d4 51.Rg8+ Kd7 52.Rd8+ The d-pawn falls and it will cost black a rook to stop the h-pawn B) 41... h5 42.Kf4! e5+ 43.dxe5 and black still has no good defense against Kg5 followed by Kxg6. Time to check the game. |

| CHESSTTCAMPS: Ouch - I saw Kf6 but missed the threat of Kf7. Still, it would be difficult for white to not win this, even without finding the most efficient way. |

| Marmot PFL: I found an easy win with 40 Bg7+ Kf8 41 Bf6, followed by Rg7+ Kf8 and Rxh7, then Kf4-g5 etc. With his king trapped Black has no play, for instance if 41...Rc8 42 Rg7+ Kf8 43 Rxh7 Rc7 44 Rxc7 Nxc7 45 Bd8 and Kxe6 winning. However the move in the game 40 Kf6 is much better. No wonder black resigned. |

| Billy Vaughan: The only move I see is 40. Kf6 with the idea of Kf7 and Bg7#. |

| chrisowen: I thought it was rather easy. I favour the king in approach. Tarrasch piles in the pieces where black cannot stop the mate threat via g7 without giving up the knight. Nd6 doesn't dig himself out of a hole. Land the knight filling in the f7 king march leaves him at his mercy and is just a goodwill act. |

| whatthefat: Unfortunately, I don't think it's sound, but I thought 40.Rd6 was interesting. |
|

| njchess: Reti gambles on a wing pawn advance with 17. ... a5 and 18. ... b4. Meanwhile, Tarrasch plays for the center 17. Ng3, 18. Rfe1 and 20. Nf5! and obtains an advantage with 21. Rxe7. Nicely done. The rest is technique. |

| Patriot: <<whatthefat>: Unfortunately, I don't think it's sound, but I thought 40.Rd6 was interesting.> You're absolutely right--it's not sound. I see no winning idea here: 40.Rd6 Nxd6 41.Kxd6 Kg8 42.Kd7 Kf7 and the black rook is free to harass white's pawns, e6 is protected by the king and white's bishop has no targets. |

| VincentL: In this "Difficult" position the threat of a back rank mate is there, if the black rook strays from the eighth rank. The black knight cannot easily manouevre to defend the pawns. Despite this, I think it must be white to play and draw. Firstly lines that don't work:
40. Rb7 Na3 41. Rb6 Nc4+ forking K and R
40. Rf7 Na3 41 Rf6 Nc4+ and the white king must retreat 40. Kf6 Nxd4 41. Rd6 Kg8.
Let's try 40. Rf7 Na3 41. Rf8+ Rxf8 42. Bxf8
Now if 42....Kg8 43. Bxa3 and white wins.
If 42....Nc4+ 43. Kxe6 restoring restoring material parity. If on move 40 black plays 40.... Nc3 then 41. Rf6 winning the e pawn next move, and restoring material equality. If 40... Rd8 41. Rf8+ Rxf8 42. Bxf8 Kg8 43. Bb4! defending both a3 and c3, thus preventing the black knight from infiltrating amongst white's pawns. 43... Kf7 Now white must be careful. Black is going to the opposition if white is not careful. 44. f3 h3 45. h4 h4 46. f4. Now black must retreat with the king or the knight. Retreating with the king allows 47. Kxe6, drawing, or 46... Na7 47. Bc5, or 46...Nc7 47. Ba5. On 47....Nb5 48.. Bb4 and the position on move 46 returns. I think this must be it. Let's see. |

| Jimfromprovidence: I did not get 34...Nd6. I liked 34 ...Rc8.
click for larger view It concedes the e pawn after 35 Rxe6, but protects against Rg7+. It also gets black's king out of jail after 35...Kf7.

| tivrfoa: nice king march |
|
| Nov-06-09 |
| Quentinc: <JimfromProvidence,> I would think that if 34...Rc8, White would just march the King up to e5 as in the game, rather than playing 35. Rxe6. Then he can take the e pawn with the King. Black does not have a lot of moves. |

| Richard Taylor: <lzromeu: Very easy. The easiest of the week.
Natural move by white.
If you see all the game it's clearly the end of king march. <Richard Taylor: Tarrasch had planned this from about move 24> Fantastic positional player> Tarrasch was anall round player adn played some very extraordinary brilliant attacks and comnbinations. When he was young he played Alkehine and won easily - in fact at that time he was a much better player. He missed the chance to play for The World Champs initially (when he was at his peak) as at first he said Alekhine wasn't good enough which was true at the time - then he coudln't get a match until he was realtively old and lost to Lasker. The other thing about Alekhine is that he avoided playing any major World Champ matches once he won the title. I have now played about 100 of his (Tarrasch's) games and they are extraordinary games. Lasker is also great and Rubinstein, and later Capa and Alekhine but Tarrasch at his peak was one of the greats. I also have books of Lasker, Alekhine Rubinstein, Capablanca and Morphy. Also, Botvinnik, Keres, Petrosian, Smyslov (who I feel is one of the greatest players) Spassky, Purdy, Sarapu, Fischer and Tal. Also I have most of Karpov's and most of Korchnoi's games. And quite a lot of Kasparov's but I want more books of his games. The more modern players are in books about openings etc as well as online.
But I would like to have collections of some of the strong players playing now. I do have a book of Anand's games but I don't feel he annotates his own games very well. But Tarrasch's games are fascinating for all aspects - endings, strategy, attacks and so on. |

| patzer2: The most surprising thing here is that Tarrash apparently prepared his fantastic King march as early as 33. f3!, eschewing the easy capture of a pawn for this amazing attack with the one piece he must defend above all others. So sometimes in Chess, as is ofen the case in sports, "the best defense is a good offense." |
