|Oct-20-07|| ||Jimfromprovidence: This post is in response to today's comments of <TrueBlue> concerning Thursday's puzzle. |
<41. Rxg7 h3 42. Rh7 h2 43. b5
Kc8 44. b6 Rd2+ 45. Ke6 Rd4 46. Rxh2 Rxe4+ 47. Kxf6 Kd7 48. Rb2 Re8 49. b7 Re6+ 50. Kf5 Re8 51. b8=Q Rxb8 52. Rxb8 Kxd6
easiest Saturday. And two days ago the puzzle was unsolvable. Is it just me or are those puzzles just getting weird?>
Thursday involved turning a game that was materially even into a victory by forcing a pawn sacrifice and the creation of a passed pawn, which then takes advantage of black’s overextended king to create a winning line of attack.
The forcing moves are 40 e6 fxe6 41 Ra8 Rd7. I then played 42 Rc8+. I believe that this move is winning because it puts black’s king in no-man’s land. If black responds 42… Kb5 or Kb6 then the black king is shut off in the attempt to stop white from advancing his King up the e file to support the f pawn’s advance. If Black plays 42 … Kd6 this eventually leads leaves his unconnected b, c and e pawns vulnerable to capture.
One continuation that worked for me is 42 Rc8+ Kd6 43 Kf4 Rf7 44 Kg5 Ke5 45 Rxc5+ Kd6 46 Rc1 e5 47 Rc8 Ke6 48 Re8+ Kd7 49 Rxe5 Kd6. As a result, black loses his c and e pawns, while white still retains his passed pawn on f6.

|Oct-20-07|| ||ConstantImprovement: <newton296 43. Ra8 mates . no need for all the drama . but your slower line wins also i would say. so count the solve.>|
That is the important thing when working out variations in your head: To consider the simple moves, too. I would not call it drama, but a nice, if negligible, variation. And: Thanks for the solve count, BUT:
After seeing the solution after 41. e5, I do not think that either you, I or anyone else (MarmotPFL for instance), who announced: "Well, 41. e5 Rd2+ 42. Ke6 and winning", got it.
The puzzle is "Very difficult" because you had to see in your mind that after 42. Ke6 Kc8 43. d7+ Kb8 the move 44. d8Q+ does not work because of 44. ... Rd8:.
So, because of the attacked white rook, one had to find 44. Ra6! and after 44. ... Kc7 the final strike 45. Rd6!, being aware that the line ends 45. ... Rd6:+ 46. d6:+ Kd8 47. b5 h3 48. b6 h2 49. b7 h1Q
So everyone who chose 41. e5 probably did not get it, but those who played 41. b5 or 41. Rg7 may claim a, though less stellar, solve.
|Oct-20-07|| ||Jack Kerouac: Carl Schlechter's moniker was 'The Drawing Master' because he could seemingly draw at will against the best. To be able to do that, you need be very, very good.Maybe not inspiring, but very hard to beat.
Kramnik is sort of the modern version of that mode of play.
Don't like his style of play? Okay.
Then try beating him.
|Oct-20-07|| ||zb2cr: Is it just me, or is this just a transposition to the White side of Thursday's puzzle? |
I went for 41. Rxg7, h3; 42. Rh7, h2; 43. b5, Rb2; 44. Kc6, Ke8; 45. b6.
|Oct-20-07|| ||Mendrys: I'll give myself partial credit (about a 40 out of 100) for this one. Like other's having seen yesterday's puzzle made 41. e5 easier to see. While I could see the basic reasons why this should win I did not do the calculations necessary to "prove" the win. I'm lazy this way and this has hurt me often in endgames. You can't really "solve" one of these puzzles in 1 to 2 seconds.|
|Oct-20-07|| ||zahbaz: Glad to say I got this quick.... vindicates yesterday. Another clever ending.|
|Oct-20-07|| ||Marmot PFL: <ConstantImprovement> Somehow I missed the announcment that you were given the task of deciding who may or may not "claim" anything. How the hell do you presume to know what I did or didn't see?|
|Oct-20-07|| ||Crowaholic: <TrueBlue: easiest Saturday. And two days ago the puzzle was unsolvable. Is it just me or are those puzzles just getting weird?>|
At least that was my impression, too. I found this one WAY easier than Thursday's. At first I wanted to look for the catch in Rxg7 (there is probably none if <MostlyAverageJoe>'s computer is right) but then thought blocking e5 is probably better because Ke6 is very dangerous for Black. The rest of the line was totally obvious. And if the black rook captures on e5, then after Kc6 the d pawn is unstoppable.
|Oct-20-07|| ||patzer2: For today's puzzle solution Schlecter plays the surprise 41. e5!, which sacrifices the pawn in order to shelter the King from the Rook's checks and make a decisive advance of the pawn on d6. This move picks up on the theme of yesterday's winning solution 50...g4! in T Wiesniak vs Kholmov, 1991.|
|Oct-20-07|| ||ConstantImprovement: <Somehow I missed the announcment that you were given the task of deciding who may or may not "claim" anything. How the hell do you presume to know what I did or didn't see?>|
My assessment about you is that you are
quite arrogant, but not half as strong. So I assumed you did not get it, but stopped after "seeing" Ke6, selfsatisfied. And be honest: I was right, wasn't I?
|Oct-20-07|| ||TheaN: 6/6.... with some spikes, though, as I missed that Rd2+ guards d8!|
41.e5! nuff said.
41....fxe5? 42.Ke6 Kc8 43.d7+ Kd8 44.Ra8+
41....Rxe5+? 42.Kc6 Ke8 43.d7+
41....h3 42.e6 (h2?? 43.Ra8#) Rd2+ 43.Kc6 Rc2+ 44.Kb6 Rc8 45.e7+
41....Rd2+ 42.Ke6 Kc8 43.d7+ Kb8! (I was looking at the normal Kd8 with Ra8+ and d8=Q, but this obviously fails to Rxd8....) 44.Ra6! and Black will lose the control of d7 and d8.
I'm giving the point as I saw all other variations, and I probably would've seen this variation OTB. At any point, even though an immediate d8 isn't possible, Ke7 will lock Black up completely. With the threat of the h-pawn it is something worthy to consider. however.
|Oct-20-07|| ||Marmot PFL: <ConstantImprovement> Easier to talk about someone over the net than face to face, now isn't it? My "assessment" is that you are a snide, condescending jerk who likes to dish it out but can't take it back. I would like nothing better than to play a few games with you and we would see if you could indeed "walk the walk" but I think we both already know the answer...
<the move 44. d8Q+ does not work because of 44. ... Rd8:> well no kidding Einstein, a beginner could see that.|
|Oct-20-07|| ||xrt999: 41.Rxg7 wins quite easily. Without too much calculation you can see that white is up a pawn, then after Rh7, white guards the h-file. White's king will come to e6 in this line as well, taking the f pawn or not. Black has no play. |
I like 41.e5 better, though, black is forced and lost completely.
|Oct-20-07|| ||znprdx: Rather feisty stuff <Marmot PFL> but it is annoying when self-appointed poobahs (like < ConstantImprovement>) see themselves as sacrosanct omniscient authorities.....|
|Sep-12-09|| ||Once: I don't know which is more enjoyable ... white's effective pawn march or reading the sparring back in 2007.|
Is it just my imagination, or isn't CG.com a much friendlier and less confrontational place these days?
Personal goal for the day: find a way to slip "self appointed poobahs" and "sacrosanct omniscient authorities" into the conversation without the wife noticing... :-)
|Sep-12-09|| ||tivrfoa: 45. ... Rxd6+
46. exd6+ Kd8
Now: Usain Bolt (pawn at b4) vs Tyson Gay (pawn at h4)
47. b5 h3
48. b6 h2
49. b7 h1=Q (Tyson Gay wins... Oo)
|Sep-12-09|| ||chillowack: <Once: Is it just my imagination, or isn't CG.com a much friendlier and less confrontational place these days?>|
"These days"? That was year before last. (I hope you're right though: it's sad to keep coming across these nasty squabbles. Let's just all be friends and enjoy the chess!)
I love Schlecter's ingenious trap: 7...Be4 8.Ra7!
He may have been "the drawing master," but Schlecter was also a great player.
|Sep-12-09|| ||lostgalaxy: 17...Nc6 trying to relocate the Knight to b5 via a7 would been sounder, I think.|
|Sep-12-09|| ||WhiteRook48: 7...Be4! should work|
|Sep-13-09|| ||Dr. J: I am having trouble finding the win if Black plays 29 ... Rxb3+ instead or 29 ... Rxf2. My main variations are:|
A) 30 Kc2 Rc3+ 31 Kd2 Rc4 32 Ke3 Rc3+ 33 Kf4 Rc2 34 Kg3(?) Rc4;
B) 30 Ke2 Rb2+ 31 Ke3 Rb3+ 32 Kf4 Rb2 33 Kg3 Rd2 34 d5 b3 35 Rb6 b2.
White does not seem to be getting anywhere. Help, please??
|Sep-13-09|| ||Dr. J: <WhiteRook48>: 7 ... Be4? 8 Rxa7! Rxa7 9 c7! wins.|
|Jun-04-12|| ||Gypsy: <Dr. J: I am having trouble finding the win if Black plays 29 ... Rxb3+ ...>|
May go something like this:
<29...Rxb3+ 30.Kc4 Rb2 31.Kd5...>
Since White now has also check-mate threats, Black really does not have much to hang his hat on. Depending on how Black proceeds, White probably arranges the passed pawn march <d4-d5-d6-d7-d8Q>; about as in the game.
