Feb-06-14  Patriot: Material is even.

64...Kf2 is one try.

65.Kf5 Kf3 66.Kg5 Ke4 67.Kg4 =

I looked at several replies and I think this is a draw.

64...g6 may be the only attempt to win.

65.Ke3 Kg3 66.Ke4 Kf2 67.Ke5 Ke3 68.Kf6 Kxf4 69.Kxg6 Ke4 70.Kg5 Kd3 71.Kf4 Kc3 72.Ke3 Kb3 73.Kd3 Kxa3 74.Kc3 Ka4

And it's clear there isn't enough time for white to play 65.Kd5 Kf3 66.Kc6 Kxf4 etc.

--------

Ok, so 64...Kg3 65.Kf5 g6+ should win similar to above. But 64...g6 loses to 65.f5!. Very tough endgame!

  ChemMac: Black needs to be a move ahead after the K side pawns get exchanged. 64...g6? actually loses after 65.f5 gf+ 66.KXf5 Kf3 67.Ke5 and White gets there first. 64...Kg3 wins for Black as shown.
Feb-06-14  morfishine: Well, I drew with 64...Kf2 and then I drew with 64...Kg3

<ChemMac> I noted comments by <master of defense> where in his post after 64...Kg3 if White plays 65.Ke3 Black "wins the race".

However, I have White winning the race after <65.Ke5> with the continuation 65...Kf3 66.Kf5 Ke3 67.Kg5 Kd3 68.Kg6 Kc3 69.Kxg7 Kb3 70.f5 Kxa3 71.f6 Kxb4 72.f7 a5 3.f8=Q+ Kc4

White also wins the race here, but Black has the advantage of having moved his a-pawn one square: 64...Kg3 65.Ke5 Kf3 66.Kf5 Ke3 67.Kg5 Ke4 68.Kg4 Kd4 69.Kg5 Kc3 70.Kg6 Kb3 71.Kxg7 Kxa3 72.f5 Kxb4 73.f6 a5 74.f7 a4 75.f8=Q+ Kc4

*****

Feb-06-14  DWINS: <morfishine>, I cranked up Stockfish and it confirms that Black wins the race.

Following your line, after 64...Kg3 65.Ke5, Black wins with 65...Kf2! 66.Ke6 g6 67.Kf6 Ke3 68.Ke5 Kf3 69.f5 gxf5 70.Kxf5 Ke3 71.Ke5 Kd3 72.Kd5 Kc3 73.Kc5 Kb3 74.Kb6 Kxa3 75.Kxa6 Kxb4

65...Kf2 is a move that I wouldn't have found either as 65...Kf3 seems to be the logical choice. However, Stockfish says that this leads to a draw after 66.Kf5 g6+ 67.Kg5 Ke3 68.Kg4 Ke2 69.Kg3 Ke3 70.Kg4

  gofer: Well there is one simple truth here, black cannot hope to take Pa3 and Pa4 and promote Pb5 before white takes Pg7 and promotes Pf4. So black must try to exchange Pg7 for Pf4. But ideally he would like the white king to have to do this as far way from Pa6 as possible, so that Black can reach Pa3 and Pb4 first! So there are only three options Kf2, Kg3 or g6. In fact after looking at this a little longer I think black is simply trying to salvage a draw! So if the king can get to touching distance of Pg7 his job is done...

64 ... g6
65 f5 gxf5
66 Kxf5 Kf3
67 Ke5 Ke3 (white is ahead by one square and so it probably winning!)

64 ... Kf2
65 f5 Kg6
66 Ke5 Kg5
67 f6 gxf6
68 Kxf6 Kf4
69 Ke6 Ke4 (white is ahead by one square and so it probably winning!)

So we need to be in the white king's face and not allow Ke5...

<64 ... Kg3>

Now I can see a couple of drawing lines for black, but is there really a win...

~~~

I didn't see the combination of Kf2 and g6 putting the white king in a bind...

Feb-06-14  morfishine: <DWINS> Fascinating, thanks! I was trying to "get the opposition" sideways, but it turns out the old fashioned way (on the file) is the correct technique
Feb-06-14  weary willy: ..g6??

  Honza Cervenka: Btw, is the gamescore correct here? For me it is quite hard to believe that after 21.Rc1 black would have played 21...Rd8?? and that white then would not have played simply 22.b4 winning the pinned Knight. I guess that 21...Qd6 and 22...Rd8 was played in the game.

  Honza Cervenka: <weary willy: ..g6??> 64...g6 loses for 65.f5!
Feb-06-14  morfishine: <Honza Cervenka> Good point, after 21...Rd8, Black gets chewed to pieces

  Penguincw: 64...g6 was a reasonable guess, although it loses.
Feb-06-14  weary willy: Yes - agree ...g6 loses - just amending my earlier ...g6?! It's efficiently demolished by f5, as pointed out immediately after my post by ChemMac and now by Honza Cervenka
Feb-06-14  WoodPushkin: Greetings:

Whites seeming opposition is busted by Blacks g♙. This is oblique opposition and comes from a pawns square control ultimately pushing enemy king to a square where he is out of play.

If White moves up Black gets behind enemy f♙. If White tries to hold opposition then g6 switches position to Blacks favor.

As Black steps up and takes away ranks forcing White up the board he has the final resource of g6 which clearly removes Whites opposition to reveal Blacks positional supremacy.

<64. Kg3!>

  Jimfromprovidence: One winning line is 64...Kg3 65 f5 Kg4 66 Ke5 Kf3 67 Ke6 Kf4. Zugzwang!

An instructive bonus to this puzzle is to play the puzzle position with white to move and see if he wins, loses or draws.

Feb-06-14  PJs Studio: At first glance whites centrally located king looks like he's winning but without deep calculations whites king needs to avoid losing by protecting his f4 pawn. If he bounces around it I'm not sure if he can hold. As much of the analysis shown her by you guys, IF white goes after the g7 pawn he loses.

So...can white hold by doing nothing?

Feb-06-14  PJs Studio: Skip my last comment. A correctly timed g6! And white will give up the f pawn and lose the race to the b and a pawns. Interesting. I have lost sleep over these endings!

I'm reminded of Bill Parcells quote:
"In football (chess) there's winning and there's misery."

  agb2002: The material is identical.

The first idea that comes to mind is 64... Kf2, aiming at either White's a- or f-pawn:

A) 65.Kf5 Ke3

A.1) 66.Kg6 Kxf4 67.Kxg7 Ke4 68.Kf6 Kd4 69.Ke6 Kc4 70.Kd6 Kb3 71.Kc5 Kxa3 72.Kb6 Kxb4 73.Kxa6 Kc4 wins.

A.2) 66.Ke5 g6

A.2.a) 67.f5 gxf5 68.Kxf5 Kd4 69.Ke6 Kc4 70.Kd6 Kb3 71.Kc5 Kxa3 72.Kb6 Kxb4 wins.

A.2.b) 67.Kf6 Kxf4 68.Kxg6 Ke4 transposes to A.1.

A.3) 66.Kg5 Kf3

A.3.a) 67.f5 Ke4 68.Kg6 Kf4 69.f6 gxf6 70.Kxf6 Ke4 and Black captures the b-pawn first again.

A.3.b) 67.Kf5 g6+ 68.Kxg6 (68.Ke5 Ke3 transposes to A.2; 68.Kg5 Kg3 69.Kxg6 Kxf4 as in A.3.a) 68... Kxf4 as in A.3.a.

B) 65.Ke5 Kf3 looks similar to previous lines.

C) 65.f5 Kg3 66.Ke5 Kf3 67.Ke6 Ke4 wins.

Feb-06-14  BOSTER: The main idea to play such ending is to attack white pawn by the black king and manoeuvring ,and using g7( g6) pawn push white king away from defending white pawn.

  agb2002: In my line C 66.Ke3, instead of 66.Ke5, draws. If I had seen this I would have considered 64... Kg3.
Feb-06-14  BraveUlysses: The endgame- so subtle, and such a potential nightmare.

My first thought was "surely black is lost".
Then- "must be a draw".

Make me wonder how many games have I shaken on for a draw, when one of us was in fact winning, or could have won.

Feb-06-14  breaker90: Everyone on here is saying 64. ...g6 loses. They say that white wins the race after 65. f5 gxf5 66. Kxf5 Kf3 67. Ke5 Ke3, etc. But it seems like Black wins after 66. ... Ke3! I think ...g6 wins as well.
Feb-06-14  C0ffeeNerd: <breaker90> After 64. ...g6 65. f5 gxf5 66. Kxf5, the black king is still on g2, so 66. ... Ke3 is not possible. Sorry. I too have tried this "stratagem" of not returning to the original position when analyzing another variation.
Feb-06-14  breaker90: <C0ffeeNerd> Ahh, I see. Thank you for the correction.
