Jul-10-10  OBIT: I see some of today's posters have pointed out some interesting ideas in the K+P endings. One of these endings can't possibly happen from the puzzle position (this is the one proposed by <dzechiel> where the c-pawn is removed), but it is interesting and instructive how Black draws with the distant opposition.

Also, <lostinspace's> line 37. Nxa6 Nxa6 38. Kb5 Nb8 39. a6 Nxa6 40. Kxa6 Kf7 41. Kb7 c5 42. Kc6 c4 43. Kc5 Ke7 44. Kxc4 Kd8 45. Kc5 Kc7 46. c4 is winning, but, as <CHESSTTCAMPS> points out, after 46...a5 Black has the opposition, and White needs a little finesse to win. However, I think 45. Kc5 is making the win harder than it has to be. Play 45. Kb5 instead, and this time White is the one who gets the opposition: 45. Kb5 Kc7 (else White plays Kb6) 46. Kc5 a5 47. c4, and now Black has to give way.

Jul-10-10  OBIT: Wow, suddenly many comments showed up about the <lostinspace> line. All I can say is, guys, play 45. Kb5 instead of 45. Kc5. See if you don't find the win a heckuva lot easier.
Jul-10-10  CHESSTTCAMPS: <OBIT: Wow, suddenly many comments showed up about the <lostinspace> line. All I can say is, guys, play 45. Kb5 instead of 45. Kc5. See if you don't find the win a heckuva lot easier.>

Agreed. When I responded to the <lostinspace> post, I was responding to the diagram and I didn't pay proper attention to the line of play that got there. I'll be more careful next time.

Jul-10-10  Marmot PFL: <White has the opposition and will win easily.>

In positions like that the extra pawn wins easily with or without the opposition.

  Jimfromprovidence: Thanks to all of the kibitzers today. Outstanding commentary concerning the opposition principle, with kudos to <CHESSTTCAMPS>.

It was your response to the position proposed by <lost in space> that gave me the Aha! moment.

I was confused because I thought once white gains the opposition as in my original diagram below, he can never give it up in order to win.

The above statement is too rigid. White can temporarily give up the opposition in order to win as long as he can force black to give back the opposition at any time! That is the case in this match; white controls who has the opposition.

Below is a viable continuation derived from the puzzle position with white to play.

Black has the opposition but it does him no good. White can follow up with Kb6 and black cannot do much except something like ...Kb8. white now has c7+, allowing his king to slide over and take both of black's e pawns, regaining the opposition. That dangerous c pawn allows him to control play.

Jul-10-10  Yodaman: And it's a Puzzle of the Day played in Netherlands!

Guess who is going to upset Spain tomorrow in the FIFA World Cup Finals?

Netherlands!

Yay! I'm from the USA and would like to call soccer football.

Jul-10-10  TheBish: Dzindzichashvili vs Ljubojevic, 1985

White to play (37.?) "Very Difficult"

Black's king is so far removed from the action on the queenside, that White breaks through with the aid of a temporary knight sacrifice:

37. Nxa6!

If it weren't for this move, the game would be a draw, as the White king has no entry point otherwise.

37...Nxa6+ 38. Kb5 Kb8 39. a6 Nxa6

(No better is 39...c6+ 40. Kb6.)

40. Kxa6 Kf7 41. Kb7 c5 42. c4 Ke7 43. Kc6 and White will win the K+P endgame with an extra pawn.

Not really that difficult, but a nice exercise none the less!

Jul-10-10  Marmot PFL: <Also, <lostinspace's> line 37. Nxa6 Nxa6 38. Kb5 Nb8 39. a6 Nxa6 40. Kxa6 Kf7 41. Kb7 c5 42. Kc6 c4 43. Kc5 Ke7 44. Kxc4 Kd8 45. Kc5 Kc7 46. c4 is winning, but, as <CHESSTTCAMPS> points out, after 46...a5 Black has the opposition, and White needs a little finesse to win. However, I think 45. Kc5 is making the win harder than it has to be. Play 45. Kb5 instead>

Simpler still is 42 c4 <instead of Kc6>. In my last comment i missed that the black pawn had reached h5. To get there I thought he needed to make 2 moves without white moving - then i saw that in this line white had squandered valuable time chasing the pawn with his king instead of just blocking and eating it.

Jul-10-10  EyesofBlue: First Saturday puzzle, I got in a long time.... and I mean a LONG time.

My regret with these puzzles, however, like most chess puzzles is that the answer is usually some kind of brazenly-looking sacrifice.

Would I have seen this if this was real game.... where a spectacular-looking sacrifice is usually NOT the answer.

I doubt it.

  NM JRousselle: Way too easy for a Saturday.
Jul-10-10  newzild: A very easy Saturday. I would have taken the a-pawn in a blitz game, I think.

  thegoodanarchist: So the Hungarian Opening is a Pirc Opening with colors reversed. I learned something new today...
Jul-10-10  M.Hassan: "very difficult" White to move. Materials even
IMO: White King is close to a & c pawns of Black. He can get closer to them,eliminate them and make way for his own pawns to achieve queening. Thus one sacrifice! 37. Nxa6 Nxa6+
38.Kb5 Nb8
39.a6 c6+
40.Kb6 Nd7+
41.Kxc6 Nb8+ (if N moves to f6 in order to take e & f pawns,a pawn is queened) 42.Kb7 Nxa6
43.Kxa6 Kf6
44.c4 Ke7
45.Kb6 Kd6
46.c5+ Kd7
47.c6+ Kc8
48.c7 h5
49.Kc6 h4
50.Kd6 hxg
51.hxg Kb7
52.Kd7 K wherever
53.c8=Q
1-0
Let's check
way too early resignation after 37.Nxa6!!
Jul-10-10  M.Hassan: <dzechiel>: Have a nice holiday and cruise.

  patzer2: For today's Saturday puzzle, the sham sacrifice 37. Nxa6! gives Black a shattered position where all Black's Knight can do is flop about like a caught fish, destined for the frying pan, while White gains the opposition to win the resulting King and Pawn ending.

P.S.: I found it easily and didn't try to work out all the details. However, I can't see Black finding any way to swindle a draw. I'm sure that's why Black resigned following this move.

Jul-11-10  tacticalmonster: candidate: 1 Nxa6

a) 1 Nxa6+ 2 Kb5 Nb8 3 a6 Nxa6 4 Kxa6 Kf7 5 Kb7 c5 6 c4 Ke8 7 Kc6 Ke7 8 Kc7 h5 9 Kc6 Kd8 10 Kd6 Kc8 11 Kxe6 Kc7 12 Kxe5

Good luck with that. Most people will look at you as if you are weird.

Jul-16-10  MaxxLange: I recently read that the word "soccer" is from an English slang corruption of "Association Football"
Aug-23-11  DrMAL: Seems an odd (and poor) version of KIA at first that turns who-knows-what but interesting. After 18...dxe4 and the rook trades, black's Q-side seemed weak. 30...Nd8?! to play on the Q-side looked dubious especially after 31...g5, why the knight maneuver then? 32.Kc4 took advantage of this. 32...g4?! lost a critical tempo for black to try and fix his losing position. With 36...Kg6? 37.Nxa6! Nxa6+ 38.Kb5 leads to white's c-pawn promoting. Solid play by Dzinzi.
Aug-23-11  SoundWave: DrMal: why are you included in the 'Hall of Lame' in I play the Fred's user profile? From what I have seen your posts are interesting and insightful..
Aug-23-11  I play the Fred: Soundwave: I spelled out in the profile that <DrMAL> frequently posts some very useful and valuable chess content; it is his relentless updates of his IGNORE list and his hypersensitivity I find troll-like.

Strange that you didn't ask me directly.

Aug-23-11  DrMAL: <SoundWave> LOL. Probably because after he got rude enough over something or another I put him on IGNORE. I was clearly right in doing so, only a troll has a hall of insult. Thanx for the compliment on my posts, I try to help, cheers.
Aug-23-11  Strongest Force: I'll say this about Roman: like Alechine, you had to beat him in opening, middle, and endgame.
Aug-23-11  DrMAL: <StrongestForce> Well, Roman was known as a great theorist in his day, earlier he was Korchnoi's second against Karpov and at this time he was helping Karpov with ideas to use against Kasparov. Later, he was Kamsky's coach for awhile before Kamsky took his law school hiatus. In 1985 he was still at peak whereas Lubo was past his peak.
