Apr-27-05  awfulhangover: Very easy puzzle. I found it in a few seconds.
But, I could easily have missed over the board! I miss easier stuff like that sometimes!
Apr-27-05  cuendillar: After reading My System, wouldn't the overprotecting 43.g3 be strong?

To be serious, nice final combination

Apr-27-05  cade: 43.Rh8 allows Black to play 43...Rf6+ and force the White King out of the action. The mate threat is gone.
Apr-27-05  zb2cr: <Saph>,

You wrote,
<I found 43.Rf8+ Kxf8 44.Kxe6 Kg8 45.Rb8+ Bf8 46.Bd6 which wins Black's bishop for White.>

Why so complicated? After 44 ... Kg8; 45 Rxe7 wins the Bishop right away. Black can't move his King further into the corner. His possibilities are 45 ... b3, 45 ... Ra2, and 45 ... Rb5, none of which seem adequate.

Apr-27-05  YouRang: I got it without much difficulty. When you notice that there is a mate threat after 44. Kxe6 (in addition to the more obvious threat to take the e7 bishop), then the benefit of the deflection 43. Rf8+ is clear.

  Gypsy: <aw1988> Well, your rook conjecture still stands. My promotion conjecture has been shot down. :-)

  kevin86: After 45 ♖h8 ♖f6+ and black uses his pin to turn the tables-after which it will be white who is fighting for his life.
Apr-27-05  alphee: <jahhaj> <Gregor Samsa Mendel> Interstingly, ♖h8 is the move ChessBase 9 indicate (with its blue arrows system) when confronted to this position if you load the game from the DB! Fritz, obviously think different<patzer2:>
Apr-27-05  aw1988: I got Monday Tuesday and Wednesday so far. 3/3 is a good track record. :)
Apr-27-05  RookFile: Sorry, I didn't have a lot of time
earlier. Rh8 is complex, but also
appears to be a good move. What I'm
looking at is: 43. Rh8 Rf6+ 44. Ke4.

In this position, white has a double
threat of 45. Rh7+, as well as 45. Bxf6. So, I see nothing better than 44... Re6.

At this point, the "quiet" move
45. Rbb8 appears quite strong, with
the threat of: 46. Rh7+ Kg6,
47. f5+! Kh5 ( ... Kxh7 48. Rh8 mate )
and now, I didn't bother to look
for a direct mate because after the
simple 48. fxe6, white still has all
his threats and has just picked off
a rook.

Probably this analysis can be tightened up even further, but the idea of Rh8 to play for mate appears to be quite strong.

Unless black has a defense to the
Rbb8 idea?

When comparing the complexities of 43.Rh8 with the simplicity of Nimzowich's own 43.Rf8+! I wonder if there still is a thing or two of tactics to learn from Nimzowich.

  patzer2: <Gypsy> Indeed 43. Rf8+! is an extremely difficult win. I worked for a while with Fritz 8 and finally gave up after:

43. Rh8 Rf6+ 44. Ke4 Re6 45. Rh7+ Ke8 46. Rb8+ Kd7 47. Rxb4 Kc6 48. Rc4+ Kb6 49. Rd4 Rb5 50. g4 Kc6 51. Rd2 a5 52. Rh2 Bf8 53. Kf5 Re8 54. Rh8 Kd5 55. Rd2+ Kc4 56. Rc2+ Kd5 57. Rc7 Reb8 58. Rhh7 Bd6 59. Rhd7 R5b6 60. Ra7 Rf8+ 61. Kg6 Kc5 62. Kg7 Bxe5+ 63. Kxf8 Bxf4 64. Rxa5+ Kc6 65. Rad5 Rb2 66. Rd3 Rg2 67. R7d4 Rxg4 68. Rc3+ Kb5 69. Rf3 Bd6+ 70. Rxd6 Rh4 71. Rf5+ Kc4 72. Rc6+ Kb4 73. Rf1 Kb5 .

With two Rooks versus Rook and Pawn, White probably wins. But who wants to go through all this, when the game continuation leads to a quick and sure win. I'm not surprised some strong program didn't pick 43. Rh8!? but it's not a practical move for human play when a move like 43. Rf8+! is available.

Apr-27-05  beenthere240: Can black defend with 41...Rf6+ (as in the proposed defences to 43. Rh8)? It drives the white king back and threatens a draw by repetition. Thus, was 41...b4 a blunder?

  Gypsy: <all> I recommend to your attention a dangerous tactical resourse for Black at the end of the game: <44...Rb5! 45.Rxe7 b3>. For instance 46.Bb2? Rb6+ drops the rook and 46.Bd6 b2 seems to offer no more than a draw by a perpetual (eg, 47.Rf7+ Kg8 48.Rg8+ Kg7 49.Rf7+ Kg6 50.g4 =). About the best is the pedestrian 46.Rc7 Rb6+ 47.Bd6+ Kg8 (Black is a tempo short for 47...Rxd6+) 48.Rc1 (White is a tempo short for 48.f5 b2 49.f6 Rxd6+) a5 49.Kd5 and White wins (by that one tempo again).

  Calli: Even 41...♖f6+ 42.♔e4 ♖c4+ 43.♖d4 ♖xd4+ 44.♗xd4 ♖e6+ 45.♗e5 is hard to hold for Black

  Calli: <gypsy> 44...Rb5 45.Rxe7 b3 46.Rf7+ Kg8 (ke8? Bd6) 47.Rg7+ Kf8 48.Rg3! wins because of the threat of Bd6+
Apr-27-05

  Calli: Actually 39...Rg6 may hold for Rudy, so 39...Rc4+ may be an error.
Apr-27-05

  Gypsy: Very nice <Calli>, as always! Thx, I searched for a resolute conclusion like that. But I walked by your sequence without noticing its full merit.
Apr-27-05  RookFile: Ok, I'm not sure I completely understand the objection to 43. Rh8.

43. Rh8 Rf6+ 44. Ke4 Re6 45. Rbb8
and now, somebody said 45.... Bf6.

So, this is no problem, 46. Rhf8+ Ke7
47. Rxf6 Rxf6 48. Rb7+ Ke6 49. Rb6+ Ke7 50. Rxf6 and soon, Rxh6.

The final position is a simple win for white.

Apr-27-05  RookFile: Also interesting is the line
43. Rh8 Rf6+ 44. Ke4 Re6 45. Rbb8
Bf6 46. Rhf8+ Ke7 47. Rxf6 Rxf6 48. Rb7+ Ke8 49. Bxf6, and now... 49.... Ra4 to save the b pawn.

What's interesting is the White
attempt to play the king up to
e6 and checkmate black. Not sure
I see a good answer to this for black.

  Gypsy: <RookFile> Well, the variation I had it mind was 43.Rh8 Rf6+ 44.Ke4 Re6 45.Rbb8! Bf6 46.Rhf8+ Kg7 (of course) 47.Rxf6 Rxf6 48.Rb7+ Kg6 49.f5+! Kg5 50.Rg7+ . Since you came up with the Rbb8, I thought you may appreciate an oportunity to give the rest.

I think this is a harder variation to compute than the game's 43.Rf8+ variation. On the other hand, White always has at least a perpetual at hand.

Apr-27-05  RookFile: Yes, Rh8 is harder for the human
brain, anyway, to calculate than
Nimzo's approach. Thanks for
your analysis. Rh8 appears also to win.

  Richard Taylor: I found this -if I wasnt tired I would have seen most of the complications OTB (there weren't too many - as far I could see looking at thepostion casually - but endings can so deceptive) - was trying to see a defence for Black but nothing seemed to work - was bit worried about Black's pawns etc

A good deflection sac - old Nimzo eh ?!

Feb-24-06  who: Why not 13...Bxa5
Aug-20-07  sanyas: <zb2cr> He probably meant 43.Rf8+ Kxf8 44.Kxe6 Ke8 45.Rb8 Bd8 46.Bf6.
