Jul-11-04  acirce: Smyslov plays the R vs R+f+h pawns ending flawlessly and shows why it is a theoretical draw, very instructive.
Oct-17-04  fgh: I tell you something: terrible play by white in the endgame.

  tpstar: "Much depends on how far advanced the white pawns are. With h- and f-pawns, a third-rank defence like Philidor's in 6.33 is not enough to reach a draw ... However, if he starts from a normal position, the attacker usually cannot confine the defending king to the back rank. The following defensive effort by endgame virtuoso Vasily Smyslov is so impressive that Mark Dvoretsky thinks that for a practical player it is enough to study it to understand the whole ending with h- and f-pawns and rook vs rook."

"Black's rook occupies a good position on b5 as it hinders the advance of White's king: <1. Rg6+> After 1. f5 Black can give checks from behind: 1 ... Rb1 2. h6+ Kh7 3. Kg5 Rg1+ 4. Kf4 Rf1+ 5. Ke5 Re1+ 6. Kf6, and then: a) The immediate 6 ... Kxh6? runs into 7. Kf7+! Kh7 8. Ra2 Rh1 (8 ... Kh6 9. f6 Rb1 10. Rh2+! Kg5 11. Kg7 ) 9. f6 . b) 6 ... Rb1! is correct: Black draws after 7. Re6 Kxh6 =. <1 ... Kf7 2. Rg5> In "Batsford Chess Endings," Speelman draws attention to Kopaev's idea (see ECE 582) 2. Kh4!? with the plan of Rg3 to cut Black's king off from the h-pawn (he argues that therefore 1 ... Kh7 might even be preferable to Smyslov's 1 ... Kf7). Black must now find 2 ... Rb1! (2 ... Ra5? 3. Rg3 Ra1 4. h6 Rh1+ 5. Kg5 Ra1 6. f5 Rb1 7. Rg4 Ra1 8. Rh4 Rg1+ 9. Kf4 Rf1+ 10. Kg4 Rg1+ 11. Kf3 Rg8 12. h7 ) 3. Kg5 Rg1+ 4. Kh6 Rf1 5. Rg7+ Kf6 6. Rg8 Kf7 7. Rg4 Rh1 = in order to draw. <2 ... Rb1!> The south-west corner is the right place for the rook. It can give check from the side or behind depending on White's winning attempts. <3. Rc5> 3. h6 Ra1! (3 ... Rg1+? 4. Kf5 Rh1 5. Rg7+ ) 4. h7 (4. Rh5 Kg8 5. h7+ Kh8 6. f5 Ra4+ 7. Kg5 Ra6 =) Rg1+ 5. Kf3 Rh1 6. Ra5 Kg6 7. Ra7 Kf5 =. <3 ... Kf6 4. Rc6+ Kg7!> This decision is of crucial importance. After 4 ... Kf7? Black's king is driven to the back rank: 5. Kg5 Rg1+ 6. Kf5 Rh1 7. Rc7+ . <5. Kg5 Rg1+! 6. Kf5 Ra1 7. Rc7+ Kh6 8. Re7 Rb1 9. Re8 Kg7 10. Re5 Ra1 11. Rd5 Rf1> 11 ... Rb1 =. <12. Rd4 Ra1 13.

Kf5 Ra1 17. h6+ Kh7!> Now Black's king has to go to the h-file so that it can take the h-pawn when necessary. <18. Rd6 Ra2 19. Kg5 Rg2+ 20. Kf6 Kxh6! 21. Ke7+ Kh7> Or 21 ... Kg7 22. f5 Re2+ 23.

Rg4+ Kf8 1/2-1/2> You should study the role of Black's king in detail. It must avoid being confined to its back rank and can stay on g7 until White plays Rg6+ or h6+. After Rg6+ both ... Kf7 and ... Kh7 draw, but h6+ forces it to go to h7."

Mar-02-08  Resignation Trap: First, the header for the tournament name is wrong. This game was from the Chigorin Memorial played in late 1947.

Smyslov had this type of endgame six years earlier (Smyslov vs Bondarevsky, 1941 ) and undoubtedly learned how to master it after studying that game. He also had advantages over players of today: after Black's 41st move and again after White's 66th move, the game was adjourned. Nowadays, games are finished in one session, and when the players reach such endgames, they are frequently playing at a very fast rate and more errors are made.

In an effort to win, White usually sacrifices the h-Pawn in an attempt to promote the f-Pawn. But if Black wants to draw, it is important to know what to do in the following position:

Smyslov's 106...Ra8! is the only move to draw in this position. For an example of a different (=losing) move see Onischuk vs S B Hansen, 2006 after White's 83rd move.

  4tmac: Extremely difficult ending. Still don't understand it. I'll come back to it later. Nice job <tpstar> on the details. Nice job <Resignation Trap> on the history and the very end. I'll just add that the checks on move 108 & 111 were "only moves".

Did White miss a win anywhere ?!

Mar-12-16  Chinchi: Howard, the answer is NO, at least from move 69.

The rook ending has now transformed to 2 pawns against 1 pawn.

FinalGen considers the position as a win for White.

Now White could have won with 64. Rf6!

Also, the great endgame specialist, Poghosyan, analyzed the above position years earlier and had come to the same conclusion as FinalGen that the attacker (White) wins.

  AylerKupp: <<Howard> Did White miss a win anywhere ?!>

I don't have any engine analysis but as g15713 indicated after 63.Rxg6 FinalGen considers the position as a win for White. This is also the first position that's amenable to Lomonosov 7-piece tablebase evaluation, and they also consider the position as a theoretical win for White, White mating in 36 moves. So since after 63.Rxg6 the position is considered to be a theoretical win for White and the game's final result was a draw, I would conclude that somewhere between moves 63 and 115 White missed the win.

You can use the Lomonosov tablebases to quickly determine where White missed the win between 63.Rxg6 and 115.Rg4+ by using a binary search. I got the following results after each of the following White moves:

(1) 63,Rxg6+ White mates in 36
(2) 89.Rc7+ Draw
(3) 76.Kg4 Draw
(4) 70.Rg2 Draw
(5) 67.Kf2 Draw
(6) 65.Rg5 Draw
(7) 64.Kf4 Draw

So it looks like White missed the win immediately after 63.Rxg6 since after 63...Rd3 the tablebases indicate that White mates in 35 after 64.Rf6, so 64.Kf4 apparently threw away the win, although there might have been other blunders by White and Black in between the tablebase positions I checked. And, of course, this would only be a theoretical win since it would require that White played the best move for the following 35 moves and that might very well not have happened, although if it did then Black probably would have resigned before then.

It would also be instructive to find out when White could first theoretically win. The first position that's amenable to FinalGen analysis is the position after 55.Kxe3 since this is the first position that contains only one piece for both sides besides kings and pawns.

Unfortunately FinalGen estimates that it would require about 2 TB of disk space and about 150 hours of analysis and I don't have either the disk space for the former or the patience for the latter. Maybe someone who is interested has a better system and more patience than I have.

Unfortunately, as chess user <AylerKupp> points out, FinalGen estimates that it would require about 2 TB of disk space when I only have 1 TB SATA drive (865 GB workable space). Instead of waiting to buy a new computer let us try to break down the position.

Game continued:

I propose 58...h4!? as a solid defense and after 59. Ra6+ Kf7 seems to draw according to Stockfish.

58. g4 is a nice try to win

F. 1.4
But Black can respond with:
58...hxg 59. fxg Rc1! - only move to draw according to my cursory analysis (Actually, FinalGen says White wins or Draw)

Those with Lomonosov 7-piece tablebases can verify this as they have an advantage as they contain the exact evaluations (draw or moves to mate) for all positions with no more than 7 pieces on the board.

which led to diagram E. 1.2 in an above post of mine

<"Gligoric played here 1.Kf4? which gave Smyslov the possibility to sacrifice his pawn and to go into a drawn ending with f- and h-pawns: 1...Ra3 2.Rg5 Ra4+ 3.Ke3 Ra3+ 4.Kf2 Ra2+ 5.Kg1 h4 6.gxh4 Kf6 =.

In fact, the position in the diagram is winning, but the correct move was missed by the players during the game and by numerous annotators in their analysis."> Poghosyan (05/23/12)

The capture of the White d-pawn was a red herring which led Black astray while White in turn missed the chance to cutoff the Black king with 64. Rf6.
