| Once: This one reminds me of Rudyard Kipling's poem "if". The poem gives a long and almost impossible list of things that you have to do to be a man. Here's the last verse: If you can talk with crowds and keep your virtue,
Or walk with kings - nor lose the common touch,
If neither foes nor loving friends can hurt you,
If all men count with you, but none too much;
If you can fill the unforgiving minute
With sixty seconds' worth of distance run,
Yours is the Earth and everything that's in it,
And - which is more - you'll be a Man, my son!
Returning to Yates-Rubinstein 1925, here is the revised version: If you can spot 72. Bg4
And that black defends with 72. ... Bb6
If you can improve on Yates with 74. fxg4
And improve on Rubinstein with 74. ... Rc2
Then you can count today's insane puzzle as solved.
And - what is more - you are a better player than me, my son. More prosaically, Fritz 11 confirms <Talinn>, <microoks> and others in that 74. hxg4 should lead to a draw because black has 74. ... Rc2 but 74. fxg4 wins for white. |

| lost in space: I deleted my post as I found the same solution as <dzechiel>. Now - with more time and reading the posts of the kibitzers, especially the one of <tallinn> - I came to the conclusion to analyse dzechiels solution once again more in detail: 72. Bg4! Bb6! 73. Rxb6 hxg4 74. <fxg4!> This move seems more natural to me as hxg4: getting rid of the double pawn, avoiding all problems with the stalemate issues. The resulting position is looking like this:
click for larger viewThe best move for Black seems to be 74. f3+ 75. Kxf3
Which options does Black have?
A: 75...Kxh3 76. Rxd6 (threat: mate Rh6#) Rd3+ 77. Ke4 Rd2 78. Kf5 Rxf2 79. Kxg5 Kg3 80. Re6 Rd2 81. d6 Rd5+ 82. Kf6 Kxg4 with big advantage for white B. 75... Rxd5? is getting mate after 76. Rb7 Rd3+ 77. Kg2 Rxh3 78. f3! Rg3+ Kf2 and there is no escape for Black. C: 75. Rd4 (seems to be the best move) 76. Rxd6 Rf4+ 77. Ke3 Kxh3 78. Re6 Rf8 79. Re4 Rd8 80. Rd4 Re8+ Kd3 Kg2 82. f4 gxf4 83. Rxf4 Kg3 84. Rd4 with a clealy won endgame for white. Of course not all moves are forced, but I think all in all: the position after 74. <fxg4> is won for white. |

| al wazir: <Manic: 75...Rc2 76.Kf1 and white wins d6 and should easily win. 75...Rb6 76.Rc1 Rb1 77.Rc4 transposes into the game after 76.Rc4.> Thanks. I didn't recognize all the threats white had. This game was a dead draw from move 43 on. I bet Rubinstein was sorry afterward that he didn't take it. |

| efrain chavez: Perhaps the most amazing fact of the game is how after move 74, Rubinstein misses a very easy draw. |
|

| jovack: I don't think white deserves to win this game.
He was not even trying to come up with something, and let rubinstein put himself in an awkward position. |

| patzer2: For today's Sunday puzzle, White plays the sham sacrifice 72. Bg4! to set up a deep passed pawn combination. In the follow-up White must avoid Black's attempt to pull off a stalemate before maneuvering his Rook to force the exchanges necessary to play 79. e5 and set up the winning 81. e6  . P.S.: The exchange of posts between <tallinn> and <manic> is interesting in pointing out the winning continuation against the more difficult defense 74...Rc2! |

| paul1959: <tallin> <manic> Black job would be simpler after 74..Rc2 75 Rc6 Rc1 76 Kh2 Rc3. White can't lose f3 as g4 would go too and Black King is freed. Looks that Rubinstein missed the draw after all. |
|
| Jul-20-08 |
| paul1959: Even clearer after 74 Rc2 75 Rc6 Rc1 76 Kh2 is 76 Rf1. White can't play 77 Rc2 Rxf2+ and 77 Rxd6 loses all three White pawns on the K side. Black keeps the rook on the first rank and White cannot win. |

| ravel5184: Wow! First Sunday puzzle solved by me in a life and a half! |

| Artar1: 72. Bg4 sets up a side-row mate. If ...hxg4, then Rh7#. 72...Bb6 is the only defense, threatening Rxf2 and the possibility of a perpetual-check draw. 73.Rxb6 eliminates the draw possibility and puts Black a piece down. Yeah! 73...hxg4 restores the material balance.
74. hxg4! pins the Black king to the h-file, setting up a possible side-row mate. Yeah! 74...Rb2! Ahhhh! &%$#$%^! I missed this defensive play for Black. Okay, so I'm biased! Oh, the agony of defeat! The rest you already know. Great puzzle.

| Lutwidge: OK, I take back my quibble about White's moves being easy to find in light of 74. fxg4(!). "Insane" is right. :) |

| Some call me Tim: Insane because of the stalemating options but I tend to agree that 74...Rc2 will draw with correct play. Anyone have a refutation? As pointed out by <JG27Pyth> if 75. Rc6 Rc1 76. Kh2 Rc3 seems to force 77. Kg2 and then ...Rc1 is back to square one. |

| TheaN: 6/7
Got the ideas of 72.Bg4 Bb6 and 73.hxg4 keeping the mate threats, but I had to work out Rc6 with a minor edge on the board it seems (would've Rb2 surprised Yates... don't think it did). Half points for Saturday and Sunday; not too bad for my doing. |
|
| Jul-20-08 |
| Salaskan: Incredibly easy. Can't believe I solved a Sunday puzzle. The black king has no flight squares, so Bg4 is immediately obvious, threatening Rh7 and mate next move. Playing Rh7 first fails because black can create a flight square with g4; the bishop blocks this pawn move. I hadn't seen the defence by black, Bb6, which threats perpetual check with Rxf2+, so white must exchange bishops, but after this, it's easy to win. I wonder, though, why didn't white capture immediately on d6 at move 75? |

| mworld: these insane puzzles boggle me. This one more so than usual. I thought bg4 led to a draw...and it seems that it does....so why is that the right answer?? were we looking for a draw here? |
|

| GoldenKnight: I actually thought this was rather obvious. White's and Black's first moves were obvious, then all White had to do was maneuver into a position where Black had to exchange rooks in such a way as to free one of his pawns, thus not allowing stalemate. Got it quickly here and could have done it OTB. Really easy for a Sunday. |

| Manic: <patzer2: The exchange of posts between <tallinn> and <manic> is interesting in pointing out the winning continuation against the more difficult defense 74...Rc2!> I think you should correct the wording. It should be "pointing out that 74...Rc2! draws" rather than "the winning comtinuation". Good analysis by <tallinn>. |
|
| Jul-21-08 |
| Dr. J: <Manic: After 74.hxg4 Rc2 75.Rc6 Rc1 76.Kh2 Rc2 77.Kg1 and black's rook must move off the c-file, say to a2. Then 78.Kf1 now d6 drops.> Not so, I think. Black can resume checking: 78 ... Ra1+ 79 Ke2 Ra2+ and I don't see how White can escape check without losing the f-pawns or restoring the stalemate position (by moving K-...-g2). At the same time I was puzzled why Manic didn't play the "obvious" 78 Rxd6 since 78 ... R-a6 fails. But this is refuted by 78 ,,, Ra1+ 79 Kg2 Ra6 draw! So this seems to show 74 fxg4 is the only way to win (OR DOES IT???) Like a lot of people I was pleased I saw the obvious Bg4 but seriously underestimated the complexity of the resulting situation. So in conclusion ... (next post) |

| Jul-21-08 |
| Dr. J: To all who claimed to have solved this problem "easily" because "Bg4 is obvious", I point out, in keeping with the Kipling theme above: "If you can keep your head when all about you are losing theirs, then you don't understand the gravity of the situation." |

| kevin86: A brilliant 64th move! The bishop,of course,is immune and,black must simplify-leading to a lost pawn ending. |

| Pawn and Two: <kevin86: A brilliant 64th move! The bishop, of course, is immune and, black must simplify-leading to a lost pawn ending.> The position was a draw after 64.Kg2, and remained so until Black's error, 71...Rd2?. Black missed the drawing move 71...Be1!. Several people have pointed out that White's position is winning after 74.fxg4!, but after the move played, 74.hxg4?, Black could have drawn by playing 74...Rc2!. |
|
Jul-23-08
|
| patzer2: <manic> <It should be "pointing out that 74...Rc2! draws"> Good point! I guess the best defense to 74...Rc2! = is to avoid it with White's winning improvement 74. fxg4! . |
