"and black is completely helpless ":30...Rd5? 31:Qg7+! 30...Rb8 31:Re4! or 30...Rf8 31:Qd2! "a sudden change in the target of the attack"31...Nb4 32:Bç3 or 31...Bb4 32:Qa2 Be1 33:Qa6 etc |

| Arthur.J.Fizelbotom: Thanks <nelech>, I don't feel so bad now for not seeing it... indeed, truly "Kasparovian" |

| Eyal: <how is Qh5 winning?> Position after 25.Qh5:
click for larger viewWhite is aiming for Qe5, and Black doesn't seem to have an adequate defense. For example: 25...Qd6? simply loses to 26.Bxc3, since Black cannot recapture (the rook is tied to the back rank). 25...Qc4 26.Qe5 Bf8 27.d6 or Bh3.
25....Nxa2 26.Qe5 Qf8 27.Be4 Kh8 (27...Bb4 28.Qf5 g6 29.Qf6 Bc3 30.Bxc3 Nxc3 31.Qxa6) 28.Qh5 Qg8 29.Bf5 Rd8 30.Qg5 and Black is under huge pressure. 25...Qf8 26.Bh3 Rc7 (26...Rc4 27.Bf1 Rc8 28.Re3 Bb4 [28...Nxa2/Na4 29.Bd3] 29.a3) 27.Re3 Nxa2 (27...b4 28.d6) 28.Bxg7! Qxg7 (28...Kxg7 29.Qe5+ and Qxc7) 29.Re8+ Bf8 30.d6. |

| jonjon2034: this is a 100% draw with perpetual check.
Rook moving from G to H file continiously checking the king. only 2 squares for king to move too are
h3. g3. g4
any other square results in loss of pawn making it a draw.... so i dont see how black wins here.. this is an easy draw to see.. i guess kasparov gave up or something. |

| AsifH: jonjon2034 it's a win!
The king can get to G1. |

Any comments on this alternative? >27.... g6. black bishop is controlling e7. |

| mjmorri: <theodor:27.... g6. black bishop is controlling e7.> Then 28.Nh6+ Kf8 29.Bf6 looks annoying if not dangerous. |

| Jimfromprovidence: If 49 Kc2, I can not find a conclusive win anywhere..

| beginner64: A better move by Karpov was 21..Ra8.
Sure, it would have been inferior to the one played, but then ALL the king's men would have been on the A file. |

| Eyal: <mjmorri: In a September post, I asked about the possbility of 27.Nf5 threatening the g pawn and Ne7+. Any comments on this alternative?> 27.Nf5 indeed looks like a very strong move - though I'd say even more for supporting the advance of the d-pawn than for the two reasons mentioned. 27...g6? which was mentioned above, for example, would lose to 28.d6! |

| jonjon2034: yes the King can get to G1.Rh3.. were in the same position reversed... Blacks King and pawn are IMMOVEABLE. allowing the rook to give check Or move of the line.. we are again in a draw position.. so break it down.
Move 71 white to play.
RG8+ black king has only one move to ensure we are not drawing. Kh3 RH8+ King mus focus on escape. Kg3
again RG8+.. Kh2..Rh8+...kg1
then RH3.
nail in the coffin its a draw... as the white king will move back and forth from e2 to f3 e1.. all key squares stopping the advancement of the black king.. so anyway you look at it.. it is a draw... unless one or both of these players give up the position. |

| jonjon2034: well there is a way out after rook e5+ the black king can create an escape but this simply leads to a queen and king ending versus rook and king. but after RH3.. Re5+ Kf3.. Kf1. Kf4.
Black queens with g1. KxE5 then its back to an unclear position. Black is up in points i guess cause black has a queen but still one of the 2 giants will have to blunder... |

Black queens with g1. KxE5 then its back to an unclear position.> There's nothing unclear about it - it's an elementary win for Black. Firstly, Q vs. R is a theoretical win, and while sometimes it may be a bit tricky for the side with the queen, here it's quite simple since the king and rook are separated, and after Qg5+ Black would soon win the white rook by a fork (if you want to see exactly how it's done, you can check a tablebase at http://www.k4it.de/index.php?topic=... - this tells you with absolute certainty the result of any position with 6 pieces and less). Secondly, Black can simply play Re2 instead of queening immediately with g1, and then White would have to give up his rook for the g-pawn. |

| Jimfromprovidence: The reason I like 49 Kc2 is the following representative but unforced line: If 49 Kc2 Kc4 50 Kb1 Rb8+ 51 Ka1, this is the position.

Black cannot succeed with 51…Rb2 because after 52 Rxb2 axb2+ 53 Kxb2 the result is a drawn position. Black cannot gain the opposition. Contrast the above position with the text position below after white’s 51st move.

Here, black can proceed with 51…Rb2 because if 52 Rxb2 axb2+ 53 Kxb2 black can gain the opposition. That's why I initially posted that I cannot find a win after 49 Kc2, because if black cannot play 51...Rb2, how else does he succeed? |

| engineerX: Karpov had a slightly funny position after 20...Qa5, but he played the endgame really well. An endgame to be studied in detail I think. |

| chessmaster.wesnny: Is there a win if he move 61. Rh5 followed by 62. Rf5? |
|

 |
| Honza Cervenka: <chessmaster.wesnny: Is there a win if he move 61. Rh5 followed by 62. Rf5?> You must have a wrong number of moves or something as 61.Rh5 is not a legal move here. The Rook is on h5 already. |

| akapovsky: wonderfull endgame by Karpov! |
|
| Jan-07-09 |
| nelech: Very strong endgame play by Karpov indeed but Kasparov dominated first and could have won with 25 Qh5!( or even 25 Qf3 ) and later with 27 Nf5 he could have taken a big advantage . This really was the turning point in the first match |
|
| Jan-07-09 |
| TommyC: Karpov should have played 21...Ra8, for the visual effect. |
|
| May-05-09 |
| scarredwolf11648: Kasparov totally lost at the end. The rook cuts off the white king from closing in on the pawn/almost queen. |
|
| Jun-15-09 |
| WhiteRook48: what about 70 Rg8+ |
|
| Jul-17-09 |
| strobane: What are the details on Karpov's recently announced rematch with Kasparov? Anybody know? |

| outplayer: 48.Kc1 is a mistake. 48.Kc3! draws. |
