Apr-04-06  Jim Bartle: This is one of those games where it's much easier to find the right move when it's presented as a puzzle.

I found the answer in a second because Be5+ is the only move that isn't an immediate draw. During play I'm not so sure I'd see it...

Apr-04-06  Alterno: What coincidence: yesterday at the club I had a similar problem (somewhat more pawns). Saw this one in a fraction of an hour.

  kevin86: This one was very easy. The text is the only move to save the pawn-and there was no winning without it. If white takes at e5,then Ke3 gains the fatal opposition.IF he refuses the sac the black bishop will hold his pawn while the black king elbows white's king away for the white pawn.
Apr-04-06  gerpm: I got it right away
Apr-04-06  dakgootje: <Saw this one in a fraction of an hour.> ah thats very nice if youre playing bullet chess ;-)
Apr-04-06  Sadistic: I think white might be able to draw with 46 Rg8 h4 47.a8=Q Bxa8 48. Rxa8 Kg2 49. Ka2 h3 50. Kb3 Be4 51. Rg8+ K anywhere and Rg6! Now if h2 then Rh6 and if the king goes back to protect the pawn then check on g6, if not then Rxh2, Bxh2 and Kxc3 with a draw. Anyone see any flaw in my analysis?
Apr-04-06  aroyni: Fritz 9. finds mate in 27 with 56.Kc4 and mate in 17 with 56.Kxc6
Apr-04-06  iamverywellatchess: Is there a puzzele of the day every day in this web-page?

If so, what a feet! It must be hard to get these players together every day! What if one of them has to do something else like shopping for food one day?

You could use my games, I guess on those days! You should let me know this and I will be happy to give you many good puzzeles from my own museum of games. Some will be very hard for many of the kabbazers here but at least they can see the genie in action!

Apr-04-06  belka: okay, it's easy to see that Be5+ is the only winning *attempt* and possible to conclude that it's therefore the solution ... yes, however:

1. it's only a Tuesday puzzle.
2. just because it's a puzzle doesn't mean black to play wins.

I don't think anyone yet has mentioned that CG reserves the right to throw in spoilers, i.e. puzzles where the obvious solution fails. Just because the move is easy to see (it's thematic!), and the only move that saves the pawn (for this turn!) doesn't imply it's the right move.

Shifting Black's king one square makes this move losing. It might happen on some other puzzle.

So, those who think it's too easy because every other move draws, therefore this is the solution, I'm sorry, but that only works in chess-puzzle land. You can't justify moves that way OTB.

Apr-04-06  acirce: You never ever "solve" a puzzle just by "finding the first move". You have to be sure about how to achieve the desired result after all critical replies.

When you are so sure that your solution works in all lines that you would be able to play it and win (or draw if that is the idea) even with only 10-15 seconds or so left on the clock, only then have you solved it.

It's annoying with all the "I found this immediately" and similar people say all the time. The time it takes until you get the idea about a likely first move is irrelevant for all purposes. It's the time it takes to work it all out that counts.

THIS position is of course simple, but it applies on them all!

Apr-04-06  EmperorAtahualpa: I knew 58...Be5+ had to be the solution, since this is only Tuesday after all. But I must say that I didn't calculate all the possibilities, and I guess many of us didn't!
Apr-04-06  YouRang: <Sadistic><I think white might be able to draw with 46 Rg8 h4 47.a8=Q Bxa8 48. Rxa8 Kg2 49. Ka2 h3 50. Kb3 Be4 ...> First, I think you mean 50...Be5 (not Be4). Second, what does White do if Black plays 50...h2?
Apr-04-06  YouRang: Hello<EmperorAtahualpa> <I knew 58...Be5+ had to be the solution, since this is only Tuesday after all. But I must say that I didn't calculate all the possibilities, and I guess many of us didn't!>

I didn't think there were that many possiblities to calculate. :-)

The main case to calculate is if White takes the bishop, but then it's easy to see that the Black's king goes to e3, d2, eats the white pawn and promotes.

If White declines the bishop, then it's standard fare for the Black king to shoo the White king away from his pawn, and again eat and promote.

Apr-04-06  hayton3: <patzer2> <58...Be5+! decoys the White King> Technically it's a 'deflection' as the king is fatally diverted away from a crucial part of the board.

  Gypsy: <hayton3: <patzer2> <58...Be5+! decoys the White King> Technically it's a 'deflection' as the king is fatally diverted away from a crucial part of the board.> It could even be argued that it is also a strange form of skewer and x-ray defense.
Apr-04-06  YouRang: It's a strange skewer x-ray deflection!

This is a case where it takes longer to assign a name to the tactic than it does to find the tactic. :-D

Apr-04-06  AniamL: I immediately found the correct move and the following mate in 27!!!!!

Oh, using a chess program doesn't count? :(

At least I found Be5+

Apr-04-06  whatthefat: <acirce>
Thank you! I couldn't agree more.
Apr-04-06  iamverywellatchess: Have I been silenced again? Does anyone here me? I need help with this web-page!
Apr-04-06  BlueMooner: If you cannot see ...Be5+ then I would suggest you stick to checkers in future?!
Apr-04-06  Chakra: I think that mose people are missing the critical point of this puzzle, that is King Pawn endings, I have played may games which were a theoretical draw but my opponent did not understand the ending. It took myself a long term to understand basic king vs king pawn endgames, as i never bother to study them
Apr-04-06  hayton3: <Gypsy> <It could even be argued that it is also a strange form of skewer and x-ray defense.> Indeed! If the king takes the bishop it's a <deflection> but it if the king goes anywhere else it's an <x-ray> defence :)

  Gypsy: <hayton3> Glad to see that great minds think likewise! :-))
Apr-07-06  LIFE Master AJ: I had an "evil cookie" problem, (spyware) earlier tonight, so I cleared all of my cookies. Then I came here to bum around, I felt like reading, but not like doing any serious work.

Of course, at first, I could not figure out what happened to my handle ...

Salutations!!!!! You are 100% correct.
