Why does black lose this game yet?

Jun-25-08  cannibal: Man, that 42.Kb5 is one hell of a move. Is there really no way to save the game for black after that? I see why 45...Kd8 doesn't help (white has enough pawn moves to get black in zugzwang), and after 44...Rd8 probably simply Kxa5 is enough (45...Rd8 46.Kc7 Rd7+ 47.Kb6 doesn't work either). Any miracle saves somewhere out there?
Jun-27-08  ravel5184: ... and now two more kibitzes! On the same day!
Jul-10-08  arsen387: This is one of the most beautiful endgames I've ever seen. 42.Kb5!! is a killer move. Also very interesting is the position after 51.Kc7, blacks are simply in zugzwang, they'll be happy not to move, coz any move loses. Any pawn move loses a pawn, and the K move allows white K to activate.

And a nice tactic is 19.Ng6! if 19..fxg6? then 20.Qxg6+ Kh8 (20..Rf7 then hxg6 wins the exchange) 21.Qxe7 and whites emerge with 2 pawns up. This is a kind of tactics I always miss during my games.

  An Englishman: Good Evening: <whiteshark>, Black is in a spot of trouble because of that pest sitting on h5. In the Classical CK, the pawn h5 can spread gloom over Black's entire position because of the subtly paralyzing effect it has on the King side pawn majority. It's a great example of Nimzo's concept of restraint in action. White's Queen side majority has no such restraints.

Black still has chances to defend. First, he must avoid touching his Queen side pawns (and I think ...a5 and ...b6 were losing). Second, he needs to hit at White's only weakness--ironically, it's his greatest strength, the h-pawn.

So 34...Rc5 comes to mind. If 35.g4, which is probably best, White no longer has the Rf4-g4 option which ties down the Black King. Now 35...Rc7, protecting the f-pawn, freeing the Black King, and threatening to double on the d-file.

Black might be able to swap off all 4 Rooks and live, because his King side can come to life. Thanks to 35.g4, Black can mobilize the King side with ...g6! If hxg6,fxg6 and Black will follow with h6-h5. Otherwise, Black plays ...gxh5; gxh5 and now his center pawns are mobile. With only one set of Rooks on the board, Black can still try to manouver his King to the c-file and his Rook to the King side and push his own pawns.

None of this guarantees that Black can hold this surprisingly difficult position--White retains his outside pawn majority. But it would have given White more obstacles to his goal of gaining the full point.

  whiteshark: <An Englishman> Thank you for your longer evaluation! I'll take a look at it and answer tomorrow.

For the danger of a special pawn structure in pawn endgames that arise after ...g6 I would like to direct you attention to my comment in Averbakh vs Korchnoi, 1965

Your will find many more <<shining examples <<>>>> in

  whiteshark: <An Englishman> I always thought that ♙h5 in the Classical CK is a longterm debt for white. Black's counterplay is on d-file, sometimes on the c-file, too. Black's kingside pawn structure is strong, w/o weakness and white's minor pieces can't enter squares g5/f5 and g6/f6 w/o sacrifice.

  whiteshark: <An Englishman> The best defence I could find in the ♖♖endgames is <34...Rc6>. The threat is 35...Rcd6, doubling rook on the d-file which white can't allow. So <35.Rd2 Rxd2+ 36.Kxd2> is 'forced'. Now <36...Kf8> is good for heading to e7 to safeguard all potential infiltration squares (d6/d7/d8) against a white rook on the d-file.

Jan-11-10  arsen387: <ounos> you're right, mea culpa, then maybe after 20...Kh8 whites should play 21.hxg6 with plenty of threats on h6, which from the first looks strong.
Nov-30-10  hannahbelle: I like this game!
Apr-26-12  Llawdogg: Wow! 42 Kb5!! What a rook sacrifice!

  NeverAgain: Indeed, threats on h6 decide the game quickly should Black take the Knight.

<19...fxg6? 20. Qxe6+ Kh8 21. hxg6> and now
a) <21...Nb6? 22. Bxh6 gxh6 23. Rxh6+ Kg7 24. Nf5#>

b) <21...Qd6 22. Rxh6+ gxh6 23. g7+! Kh7> (<23...Kxg7?> drops the Queen to <24. Nf5+>) <24. gxf8N+> (heh, 24. gxf8Q comes to the same thing - all the same Black can't take the e6 Queen, the new one would take on h6 with check) <24... Rxf8 25. Qf5+ Kg7 26. Qf3>

and in addition to being a piece down (for two pawns) Black will have to give up his Rook to parry the threats to the Queen and the h6 pawn. Stockfish 6 considers <26... Ng8 27. Nf5+ Rxf5 28. Qxf5 Qg6 29. Qxg6+ Kxg6 30. dxc5 Nxc5 31. b4 Ne6 > (eval: 1.85 depth: 34)
