|Sep-26-07|| ||HFlew: I think I would have missed this in an actual game. The first 2 moves I looked at were the pawn moves, but the B can catch them. Then, because I knew it was a puzzle, I looked harder and found Kd4.|
|Sep-26-07|| ||fm avari viraf: One cannot become a good Chess player without learning the "end game". Though, it is last phase of the game, mostly chess players tend to neglect. Therefore, learn the "end game" thoroughly & be victorious! Here, Black cannot lose the game & so he employed the technique of 2 distant passed pawns where the White Bishop stood in vain & died in despair!|
|Sep-26-07|| ||chessamateur: I got this but of course it took awhile because I looked at the 2 pawn moves first. I doubt I would get this in a blitz game but I'm sure I would find it in a slow game. Nice puzzle either way.|
|Sep-26-07|| ||cu8sfan: I always thought endgames were boring until I started going through "Fundamental Chess Endings" by Müller/Lamprecht. Ever since, I'm hooked. I just love endgames, especially pawn endgames. And you know, it's correct: "When you study an opening, you're learning an opening, but when you're studying endgames you're learning chess." Don't know who said it (Lasker?)|
|Sep-26-07|| ||greensfield: It's not long before you see 62...Kd4, and when you do, its all over for white.|
|Sep-26-07|| ||YouRang: <cu8sfan: I always thought endgames were boring until ...>|
Funny, I've always loved endgames, but I find openings boring. Of course, this probably has something to do with why I stink at openings. :-)
|Sep-26-07|| ||cu8sfan: <YouRang> Well, at the level I play, if I get out of the opening unscathed and can survive the skirmishes of the middlegame I know I have a great chance to win because most players don't concentrate on the endgame. Then again, surviving the middlegame is easier said than done. (-:|
|Sep-26-07|| ||patzer2: Black's 62...Kd4 provides an amusing finish and an instructive endgame tactic for today's puzzle solution.|
|Sep-26-07|| ||playground player: Funny: the winning move jumped right out at me, and no other move ever suggested itself. But then I usually win endgames, except when I make a really bonehead play. It'd be nice if I could get those out of my repertoire!|
|Sep-26-07|| ||YouRang: BTW <cu8sfan>, I found this quote:|
<If you have any doubt what to study, study endgames. Openings teach you openings. Endings teach you chess.>

|Sep-26-07|| ||mpmeints: psmith: <mpmeints> After 54...axb4 55. cxb4 Bxb4 56. Kf3 White easily blocks the Black pawns. Black can't make progress. Opposite colored Bishops leads to a draw. (Correct me if I'm wrong.)|
I have not worked it out, but I would think that with the pawns on black and a bishop on dark to protect from a distance, black could move his king in and force whites king out and/or force white to sacrifice a bishop and then advance the a pawn.
But I do see the why the pawn become as if not more important to keep in this situation.
|Sep-26-07|| ||pawnofdoom: There were only like three considerable moves in thsi position, so that makes it pretty easy. g2 fails after Bxg2. If you try to continue with b2 then the bishop goes back and the game is drawn. If c2 first, then Kxg3 and all winning chances are lost. But Kd4 attacks the bishop ina way and wins.|
Its cool to have two pawns against a bhishop in an endgame like this. Technically black is down material, but here, white has no chances to win unless somehow black gets his king to b1 and his pawn to b2, while black has a Kb3 and then plays Bd3#, which is like impossible
|Sep-26-07|| ||outsider: damn. i knew the game and remembered the solution immediately. wish i had a chance to solve it, it's so cute...|
|Sep-26-07|| ||YouRang: <pawnofdoom><white has no chances to win unless somehow black gets his king to b1 and his pawn to b2, while black has a Kb3 and then plays Bd3#, which is like impossible>|
I think you're mistaken -- there is actually no way for white to mate black. In the situation you described, after Bd3+ black has ...Ka1.
|Sep-26-07|| ||gambitfan: < mpmeints: I wonder why at move 54 black sacrifices the bishop instead of taking the pawn with the pawn and then exchange pawns or take both and have a more significant advantage(materially).|
It seems that a full two pawn advantage at that point would have also led to a win.
You asked an interesting question...
At move 54, Black exchange a Bishop against 2 pawns... which is not such a huge sacrifice...
Black must have calculated bery precisely the promoting chances of the pawns...
Would Black have won more quickly if they had made the exchange you suggest?
It would be interesting to checj, but I am not convinced of it...
|Sep-26-07|| ||euripides: <After 54...axb4 55. cxb4 Bxb4 56. Kf3 White easily blocks the Black pawns.> It's a dead draw. For instance White can put the king on g2, play Be2-f3, and then move the bishop up and down the f3-a8 diagonal. Black's king can never attack more than two squares on that diagonal so the bishop will never run out of moves; g2 is occupied by the king and f3 is protected by the bishop and king, so there is no way to break the blockade.|
|Sep-26-07|| ||TheaN: 3/3
Better late than never (although I already solved this one in the afternoon I didn't post). Black overloads the only compensation White has for the pawns:
63.Bb1-h7 (Bd3 Kxd3) g2.
63.Bh1-a8 b2 64.Be4 g2.
|Sep-26-07|| ||MostlyAverageJoe: <realbrob: In your opinion, what's the ranking one should have to solve this puzzle easily? 1400?>|
My 7-year old son has empirically demonstrated that rating of about 850 ELO is sufficient to solve that puzzle. His explanation of why Kd4 wins was completely satisfactory. Took about 30 seconds.
|Sep-26-07|| ||gauer: Is this an example of Opposition in an ending of type non: K + P(s) vs K + 0 or more) * (P(s)) ?|
Once white has played 62 Kxf4, it does appear that def iii of mutual zugzwang is satisfied, and had to also check whether the related definitions of corresponding squares or mined square(s) or trebuchet or triangulation were present, and they don't appear to be.
In some cases, certain types of
K + P(s) + Kt(s) vs K + 0 or more) * (P(s)) or K + P(s) + Kt(s) vs K + 0 or more) * (P(s)) + Kt(s) or K + P(s) vs K + 0 or more) * (P(s)) + Kt(s) can occasionally play very similarily in strategy to the above mentioned ending (Knight endings added to Pawn endings are approximated well by Pawn endings).
Does anyone know of a catalogue of Oppositions for small-sized Pawnless endings? It would be wonderful to see Fritz or similar switch on an opposition warning light as part of its themed annotatings.
|Sep-26-07|| ||cionics: This must be an "easy" puzzle for Wednesday since I got it in about 10 seconds! This is not typical for me.|
|Sep-27-07|| ||not yet a patzer: <MostlyAverageJoe> I <DO NOT> need you bringing me down from my delusional visions of grandeur by informing me that your 7-year-old son also was able to solve this problem.|
Sheesh! Back to my miserable chess idiot, not yet a patzer life.

At the level I play, if I get out of the opening unscathed and survive the skirmishes of the middlegame, it's because my opponent resigned somewhere along the way without me noticing...
