Mar-24-18  Clemens Scheitz: <Big Pawn's "laughably wrong and arrogant about it too" >

<perfidious, ...you mean in the same inimitably style as you? >

Thanks <perfidious>, you really made my day. What a beautiful example of hitting the nail in the head.

Mar-24-18  jrredfield: Like others have said, this definitely was the easiest Saturday puzzle ever for me. I was actually on the phone taking care of something and decided to go to this page and be ready to solve it after my call was done, but it was so easy that I got it in about 5 seconds even while on the phone. 54.Rxc6 is the only way to break the pawn deadlock, and Black's king is too far away.
Mar-24-18  SEVEN: Oh boy! I love pawn chains.

  Jimfromprovidence: Let's see what happens if we re-purpose the puzzle. If the king is on a4, below, with white to move. does he still win?

Mar-24-18  Andrew Chapman: 'After 54. Rh7+ K any 55. Rxb7, there's no way to prevent promotion. Black's goose is cooked, and so is the puzzle.'

54Rh7+ Rg8. Which explains 53...Kf7

White can play 54.Ka5 and then wait for the rigth moment to play Rxc6. Of course 54. ... Rg6 can destroy his plan

  Mendrys: The hard move, if it can be called that on a Saturday puzzle, is 55. b7.

If 55. Kxa6 then black has an interesting and instructive tactic:

(55. Kxa6 g4 56. fxg4 Rxg4! 57. hxg4 h3 58. gxh3 f3) and the pawn will queen with check. White should still be winning but it will be much harder with Queens on the board. Stockfish pointed this out to me last night and it's something to keep in the toolbox and hopefully recall if approaching a similar pattern in a game.

Mar-24-18  SEVEN: Hendrys, I think Stockfish overlooked something. After 55. Kxa6 g4 56. fxg4 Rxg4 white still can win with 57. b7 No?
Mar-24-18  WorstPlayerEver: <SEVEN>

55. Kxa6 g4 56. fxg4 Rxg4 57. hxg4 h3 58. gxh3 f3 59. b7 f2 60. b8=Q f1=Q+ 61. Kb6 Qb5+ 62. Kc7 Qa4 63. Qb7 is far more complicated than 55. b7

Nothing to do with Stockfish...

1.0 minute analysis by Stockfish 9 v010218

= = =

Hard to calculate, though

Mar-24-18  AlicesKnight: The break is easily seen as it is the only real possibility of something decisive. But it has to be played precisely. A pity Myagmarsuren seems to get noticed solely for his brilliancy (loss) to Fischer at Sousse in 1967.
Mar-24-18  Cheapo by the Dozen: I made a miscalculation that made the win look even easier than it is -- but yeah, this is the sort of thing that most of us could imagine finding over the board. Easy for a Saturday.
Mar-24-18  morfishine: <whiteshark> Nice point about accuracy!
Mar-24-18  Albion 1959: I did experiment with this opening for black, but quickly gave it up. It is too passive and is not easy to gain active piece play and was not conducive to my style of play. It needs a certain mind set to play these types of positions as black. As the game pans out, black gains nothing and adopts a bunker mentality in an attempt to hold out for a draw. On move 30, for better or worse black should have at least tried g4!? to open lines and generate counter play, rather than be slowly squeezed and ground down. The plan of white king to a5 is in effect the only logical plan that could have worked. However, this in itself should not been enough to win. It needed a mistake from black on move 53.Kf7?? before white could make the break through. Better was 53. Kd8, thought after 54. Re6 the pawn on e5 falls and is in the lead. The concept of sacrificing the rook on c6 is just about the only way that white can force a win here, inspired, logical and yet so simple !

  Breunor: Well I saw it right away but I doubt I would have found it over the board. Unfortunately this is the worst kind of position to say 'white to play and win' since Rxc6 is the only real possibility.
Mar-25-18  ruzon: <Cheapo by the Dozen> Except White found that win on move 42!

  al wazir: <ChessHigherCat: I guess that's how you can tell who has you on ignore: 54 Rh7+ Rg7 55. Rh8 Rg8 56. Rf6>. I'm not sure what your reference to "ignore" means (I can see your posts quite clearly) -- nor how you move the ♖ from h8 to f6.

<tpy: It is Friday night so perhaps aL wazir overindulged in his favorite intoxicant thus explaining both the error and the attitude of his post.> No intoxicant.

<perfidious: Probably <wazir> put the king on the wrong square in his analysis>. I might have been looking at the position one ply earlier. But I think it's simpler than that: I just goofed

Mar-25-18  SEVEN: WorstPlayerEver: Watch out my line please. After Kxa6 g4 56. fxg4 Rxg4 I recomment b7 immediately. Dont capture the rook with hxg4

  ChessHigherCat: < al wazir: <ChessHigherCat: I guess that's how you can tell who has you on ignore: 54 Rh7+ Rg7 55. Rh8 Rg8 56. Rf6>. I'm not sure what your reference to "ignore" means (I can see your posts quite clearly) -- nor how you move the ♖ from h8 to f6.>

In other words, instead of admitting that you were totally wrong and arrogant about it on top of that (for once Big Pawn has a point), you seize the opportunity to be gratuitously snotty once again by carping about an obvious typo and ignoring the fact that R+ is bad, as I had clearly stated (which is why I assumed you had me on ignore).

Bravo, you have excelled yourself!

Mar-25-18  WorstPlayerEver: <SEVEN>

Sorry, but I think it comes down to the same conclusion: too complicated. Although White is winning.

55. Kxa6 g4 56. fxg4 Rxg4 57. b7 Rxg2 58. b8=Q f3 59. Qxe5 Ra2+ 60. Kb6 f2 61. Qf4+ Kg8 62. Kxc6 1-0

Mar-25-18  WorstPlayerEver: <..by carping about an obvious typo> <CHC>

No, no, no, you cannot blame another user for your typos! Even when I have that user on ignore myself!

The way I see it: you confuse yourself too often; Bishops won't go from f6 to a3 and Rooks do not move from h8 to f6..

You should try 'Noir Chess'. A training app based on squares and their relationship. Albeit it's very simple, it really is a useful app IMHO

  ChessHigherCat: I admit I'm very bad at notation because I just learned playing blitz and the little notation I learned was old style "Pawn to King 4", but it takes a good deal of bad faith to misunderstand this "Checking the king doesn't do any good, because black just interposes the rook....54 Rh7+ Rg7 55. Rh8 Rg8 56. Rf6" Everybody makes mistakes (even the illustrious you) but deliberately capitalizing on them is childish.
Mar-25-18  WorstPlayerEver: <CHC>

Yeah yeah, I know chess is confusing; Bf6 instead of Bd6 😶
