 | | jahhaj: <al wazir> Agreed, about the only endgame knowledge needed for this puzzle is the    vs is not normally a win, so 75. gxf8= + is not a solution to this puzzle. |
 |
| Aug-25-05 | | sfm: Another neat detail: I wondered why white played 71.Kh6,Be3+ 72.Kg6. Why not just 71.Kg6 ? Because of 71.-,c2 72.Bxc2, e4 and black eats the g-pawn in time. But with the black bishop on e3 that defense is gone, white gets his bishop to point at e6 before black can grab g7. |

| Aug-25-05 | | teme: <cade: I got this really fast, 4.5 seconds.> LOL nice joke |
|
| Aug-25-05 | | prinsallan: Very forcing moves and very easy to spot...
But i didnt as usual. Im having a rough week ;(
I was looking at 75. Bxe6+ and thinking that this line was forced: 75... Rxe6 76 Rd8 Re8 77 Rxe8 c2 78 Rxf8#Of course... I missed that 75... Rxe6 isnt just Rxe6... Its Rxe6+ and the tempo wins it all for black. Im off for this week, cya next week and have a great weekend all. |

| Aug-25-05 | | aginis: How about
75.gf=+ xf8 76.f6!
A. 76...g8 77.xe6+ f8 78.f7+ g8 79.g7++ h8 80.g1 f8+ 81.f7  B. 76...c8 (or b8, a8) 77.xe6 e8 (77...c2 78.h7 any 79.h8#) 78.h7 C. 76...c2 77.xc2 a8 78.g6 e4 79.h7 g8 80.g7+ h8 (80...f8 81.f7 ) 81.f7 e5 82.g1 a6+ 83.e6 a7 84.c1 e3 85.c8+ h7 86.f5+ h6 87.h8+ h7 88.xa7# D. 76...e4 77.g7! c2 78.g1 c1= 79.xc1 g8 80.g1+ h7 81.xe6 f8+ 82.f7 in this case the black pawns protect the white king in his strong position. Combined with the fact that the black king is pressed against the wall this allow white to win a RBvR endgame. |

 | | Richard Taylor: This was a fascinating game - Svesnikov's sac of his b pawn was almost heroic - I saw the solution quite quickly but this is all very instructive (as they say in the trade) - |
|
| Aug-25-05 | | aginis: An addition to my earlier post.
E. 75.gf=+ xf8 76.f6! c2! 77.xc2 e4! 78.xe4 b8 (78...e5 79.d5 ) 79.g6 e5 80.d6 g8 81.f7+ f8 82.e6!! e4 83.e7 e3 84.e6 e2 85.h7 e1= 86.h8# |
|
| Aug-25-05 | | Happypuppet: aginis, in variation B, what if Black plays 77.. Ke8? |

 | | kevin86: I looked at this one backwards:I saw d8 not as a sacrifice,but as an attack on black's rook and a pseudo pin on said rook-against the bishop. The rook is overworked-it cannot both guard the last row and the pawn at e6. It only took the coaxing of the white rook to show this weakness. The final position is amusing,black can queen-but the king can only wait for the coroner to arrive. Yes,he is not mearly dead-but really most sincerely dead! |

| Aug-25-05 | | homersheineken: Yeah, My first Thrusday!!! I saw that one in about 3 seconds....Probably my fastest ever. But i'm sure tomorrow will squash my fragile confidence :) |

| Aug-25-05 | | avidfan: A suimate
75.Rf7 Ba3 76.Rf1 Re7 77.Rf8#
or 76...Rb8 77.Bxe6#
or 76...Rf8 77.Bxe6+ 78.Rf7 79.Bxf7#
but the text move is so much more elegant!
The e6 pawn is a shield for Black's king on the long g8 diagonal, as well as a liability in defence by disallowing lateral checks from the rook. 75.Rf7 Bxg7 76.Rxg7+ Kh8 77.Kh6 Rg7 78.Rh7#
Is this the same Sveshnikov of the Sicilian Defence variation?

| Aug-25-05 | | ThomYorke: When people solve the puzzle itīs easy, when they donīt itīs hard. Nice theory... |
|
| Aug-25-05 | | aginis: <happypuppet> good catch
if 76...b8 77.xe6? e8=
instead 76...Rb8 77.Rh7 Kg8 78.Rg7+ Kh8 (78...Kf8 79.Bxe6 any 80.Rg8#) 79.Bxe6 c2 ( 79...Rb2 80.Rg8+ Kh7 81.Rd8 Rb6 82.Rd1 ) 80.Rg2 Rb7 81.Rxc2 e4 82.Rc8+ Kh7 83.Bf5+ Kh6 84.Rh8+ Rh7 85.Rxh7# you've caught the main point of this position black must move his king to e8 or remove the white king from his stronghold on f6 in order to draw. |
|
| Aug-25-05 | | aginis: <ThomYorke> the puzzle is easy if the first move sticks out like a sore thumb (never mind that you have no idea what the second move should be) and its hard if the first move requires some foresight. tuesdays puzzle is a perfect example.
objectively the puzzle was easy, the way these guys think the first move doesn't create any weaknesses so its hard to find and thus complaints of a hard puzzle. |

| Aug-25-05 | | chessic eric: <avidfan> Are those lines you've posted "76...,Black to play awfully and lose?" I don't know where to begin... Very nice puzzle CG, a few interesting possibilities (75.Rd8, 75.Rf7, 75.Kf6) which require some legwork (as <aginis> posted) to decide which is best. I did choose 75.Rd8, but did anybody else analyze 75.Kf6? Seems to decide the issue pretty quickly, but I'm interested to hear what y'all think... |
|
| Aug-25-05 | | HastyMover: <ThomYorke: When people solve the puzzle itīs easy, when they donīt itīs hard. Nice theory...> I disagree wholeheartedly. The ONLY ones I ever get are the hard ones. I keep telling myself that. It's a real boost to my self esteem. :~) |
|
| Aug-25-05 | | aginis: <chess eric> 75.f6 c2! 76.xc2 e4! 77.xe4 c8 78.g6 c6 79.a7 e5+ 80.g5 e4 looks like a draw and i think it works for 75...f7 as well |
|

 | | YouRang: Got it! At first it looked difficult, but when I realized that Bxe6 was mate, if only the black's rook was not protecting e6, it was obvious to attack/deflect black's rook with Re8. |
|
Aug-25-05
 | | jamesmaskell: I didnt get it :( I guessed Kf7 wrongly. I can now she how the bishop can escape then you're done. I reckoned it would be Rf7 Re7/ Rxf8 mate. Re7 though would be a ridiculous move though for Black. Oh well...its getting to the end of the week... |
|
| Aug-25-05 | | snowie1: gxf8+...Kxf8 76Ba4...Ra8 77 Rf7+...Kg8 78Rg7+...Kh8 79 Rh7+...Kg8 80 Bb3+...and the cowboy must move to the f8 square he liked so much. But the text was faster and a nice move. |
|
| Aug-25-05 | | aginis: <snowie1>
80.Bb3 isn't check in your line
there is still a pawn on e6
not to mention that you haven't considered 76.c2 as a defense
or 76.Rc8 both are stronger than the proposed Ra8 which sets up for a skewer on the back rank. |
|
| Aug-25-05 | | black knight c6: relatively easy to see puzzle, Rd8 making use of the Bxe6# threat, but great pawn sac by Svesh. |
|
| Jul-27-09 | | WhiteRook48: 75 Rd8 ha! |
