| Jul-25-15 | | gofer: <27 Rxe6 ...>
This move has tow very important aspects;
a) defending Pe7
b) removing the defender of Pf7 (or the f7 square which ever you prefer) 27 ... fxe6
28 Qxe6 mating
Black has to find a defence...
<27 ... Qxa6>
<28 Rxf7! ...>
Now black is in trouble the king cannot take Rf7...
28 ... Kxf7
29 e8=Q+ ...
29 ... Rbxe8
28 g6+ Kg8
29 Rxe8+ Bf8
30 Qe6+ Kg7
31 Qf7+ Kh6
32 Rxf8 
29 ... Rhxe8
28 g6+ Kg8 (Kf8 Qf2+/Qf3+/Qf4+ Kg8 Qf7+ Kh8 Rxe8+ mating)
29 Rxe8+ Bf8 (Rxe8 Qxe8+ Bf8 Qf7+ mating)
30 Qe6+ Kh8
31 Qf6+ Kg8
32 Qf7+ Kh8
32 Qh7#
So what can black do???
~~~
Yeah! A nice clean Saturday puzzle solved! |

|
| Jul-25-15 | | patzer2: Here's my look at the game and today's Saturday puzzle (27. ?) with the chessgames.com Opening Explorer (OE) and Deep Fritz 14 x 64: <1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 d6 6. Bg5 e6 7. Qd2 a6 8. O-O-O h6> This is the second most popular option in the OE. The most popular move is 8...Be7 as in Short vs Kasparov, 2015. <9. Be3 Bd7> The popular move is 9...Be7 as in Junior vs Loop, 2007. <10. f3 Qc7> The popular move is 10...b5 as in
S Zhigalko vs U Eliseev, 2013. <11. g4 Ne5 12. h4 b5 13. Rg1 h5?!> This is the only move in the OE with 13...h5? And rightly so as it allows White to take the initiative with advantage after 13..h5? 14. g4  to  . Instead, Black can hold with 13...b4 as in
Lahno vs D Kononenko, 2003. <14. g5!> With this strong move, White begins to take control of the game. Less strong is <drunkenknight>'s 2002 suggestion 14. gxh4 when Fritz indicates play might continue 14...Nxh5 15. f4 b4 16. Ncb5! axb5 17. fxe4 Rxa2 18. Kb1 Ra8 =. <14...Ng8 15. Be2 Rb8 16. f4 b4 17. Nb1 Ng4 18. Bxa6 g6 19. Rgf1 Nxe3?>
This allows White a strong advantage.
Instead, Fritz indicates Black can hold with 19...Ne7 when play might continue 20. Bd3 Nxe3 21. Qxe3 Qb6 22. Qf2 Bg7 23. Nb3 Qc7 = (+0.21 @ 21 depth, Deep Fritz 14). <20. Qxe3 Ne7 21. f5!> This pawn push gives White a strong attack. <21...gxf5 22. exf5 e5> Not 22... exf5? when play might continue 23. Nxf5 Rb6 24. Be2 d5 25. Nxe7 Bxe7 26. Rxd5 Rd6 27. Re5 Re6 28. Rxe6 Bxe6 29. Bb5+ Bd7 30. Qd4 Rf8 31. Qd5 Bxb5 32. Qxb5+ Qd7 33. Qb8+ Qd8 34. Qb7 Qd7 35. Qa8+ Qd8 36. Qe4 Qd6 37. Rd1 f5 38. Qf3 Qe6 39. Qxh5+ Rf7 40. Nd2 (+6.69 @ 21 depth, Deep Fritz 14 x 64). <23. f6> Here Fritz prefers the winning alternative 23. Nd2! when play might continue 23... Rb6 24. Bc4 d5 25. Bb3 exd4 26. Qxd4 Rh7 27. f6 Ng6 28. Qxd5 (+3.57 @ 20 depth, Deep Fritz 14). <23... exd4 24. Rxd4 Be6 25. fxe7 Bg7 26. Re4 Qa5 27. Rxe6!> This solves today's Saturday puzzle. I found it but my follow up was not as strong as the game continuation. <27...Qxa6 28. Rxf7 > (+11.46 @ 21 depth, Deep Fritz 14).
This is the strongest follow up, but white also wins with 14. Qf4, 14.
Qf3 or 14. Qf2.
My follow up solution was 28. Qf4 which wins after 28...Qxf1+ 29. Qxf1
fxe6 30. Qa6 Kf7 31. Qxd6 Rhe8 32. Nd2 Rb7 33. g6+ Kg8 34. Ne4 Rbxe7 35. Qxb4
(+5.07 @ 20 depth, Deep Fritz 14).
<28... Kxf7 29. e8=Q+ Rbxe8 30. g6+
Kg8 31. Rxe8+ Bf8 32. Qe6+ 1-0>
Black resigns as it's mate after 32...Kg7 33. Qf7+ Kh6 34. Re6 Qf1+ 35. Qxf1 Be7 36. g7+ Kxg7 37. Rxe7+ Kg6 38. Qf7+ Kh6 39. Qg7#. |

| Jul-25-15 | | morfishine: Great finish by Karpov. I was thinking this was that great game vs Topalov Karpov vs Topalov, 1994 But then realized this was a different game Here, I had <27.Rxe6> followed by 27...Qxa6 and now <28.Rxf7> which is pretty much the highlight of the combination; continuing 28...Kxf7 But now I played 29.g6+ Ke8 30.Qf3

Which felt strong since 31.Qf7+ seems hard to meet

| Jul-25-15 | | wooden nickel: This is a match between two great players. There are many moves to try today all over the board.
<al wazir: My idea (for what it's worth) was 27. Qa7 ...>
Well, that was sure worth a try.
Also 27.Qf2 (or Qf3?!) seems to be a strong move!
If 27... Qxa6 28.Rxe6 Qxf1+ 29.Qxf1 fxe6
click for larger viewOf course the played 27.Rxe6! is the real winner, but only if one spots the following 30.g6+!
That little bastard (pardon my Bavarian!) ruins Black. |
|
| Jul-25-15 | | alshatranji: What about 28.Qf3? White threatens Qxf7#, and there doesn't seem to be a good defense. |
|
| Jul-25-15 | | alshatranji: Wooden nickel had a similar idea, but I think the queen move is stronger after Rxf6. |
|
| Jul-25-15 | | patzer2: <alshatranji: What about 28.Qf3?> White wins, though it's not as strong as the game continuation. White wins after 28. Qf3 Qxf1+ 29. Qxf1 fxe6 30. Qa6 Kf7 31. Qxd6 Rhe8 32. Nd2 Rb7 33. g6+ Kg8 34. Ne4 Rbxe7 35. Qxb4 (+5.07 @ 20 depth, Deep Fritz 14). |

|
| Jul-25-15 | | patzer2: If 29...Rhxe8 (diagram below),

|
| Jul-25-15 | | thegoodanarchist: van der Wiel lost because he chose too many of the same moves I would have chosen. |
|
Jul-25-15
 | | Jimfromprovidence: 27...Bxb2+, assuming 28 Kxb2 fxe6, throws the puzzle into a nice alternative ending, for those interested.

 | | agb2002: White has a bishop, a knight and two pawns for the bishop pair. Black threatens Qxa6 and Kxe7.
The bishop on e6 protects f7. This invites to play 27.Rxe6: A) 27... fxe6 28.Qxe6 (28.Qf3 Kd7 29.Qf7 Rbe8, unclear) 28... Qxa6 29.Qf7+ Kd7 30.e8=Q#. B) 27... Qxa6 28.Rxf7
B.1) 28... Kxf7 29.e8=Q+ (29.g6+ Ke8, unclear)
B.1.a) 29... Rbxe8 30.g6+ Kg8 (30... Kf8 31.Rxe8#) 31.Rxe8+ Bf8 32.Qe6+ Kg7 33.Qf7+ Kh6 34.Rxf8 wins. B.1.b) 29... Rhxe8 30.g6+ Kf8 (30... Kg8 31.Rxe8+ and mate soon) 31.Qf4+ Kg8 32.Qf7+ Kh8 33.Rxe8+ Rxe8 34.Qxe8 Bf8 35.Qxf8#. B.2) 28... Rg8 29.Qf4 with the threat 30.Rf8+ Kd7 31.e8=Q+ Rxe8 32.Qf7+ looks winning. |

| | agb2002: <Jimfromprovidence: 27...Bxb2+, assuming 28 Kxb2 fxe6, throws the puzzle into a nice alternative ending, for those interested.> I considered Bxb2+ for a very short moment and forgot it even quicker. Probably because after 28.Kxb2 fxe6 29.Qf2, aiming at a7 and f7, Black looks defenseless. |
|
| Jul-25-15 | | alshatranji: Thank you patzer2 for the analysis. I wouldn’t want to argue with Deep Fritz, but after 28. Qf3 Qxf1+ 29. Qxf1 fxe6, the move 30. g6 is worth considering: 30 … Bh6+, 31. Nd2 Kxe7, 32. Qf7+ Kd8, 33. g7 |
|
| Jul-25-15 | | patzer2: <alshatranji> Yes 28. Qf3 Qxf1+ 29. Qxf1 fxe6 30. g6 (+3.84 @ 24 depth, Deep Fritz 14 x 64) also wins. |

Probably because after 28.Kxb2 fxe6 29.Qf2, aiming at a7 and f7, Black looks defenseless.> Missed that move. I was looking at 29 g6, seeing that black could exchange queens after which white could put his rook on f7 and get his knight into play.

|
| Jul-25-15 | | morfishine: <Jimfromprovidence> I too pondered 27...Bxb2+ probably for about as long as <agb2002> if not shorter, mainly because the White Knight prevents Black Queen from entering via <a3> ***** |

| Jul-25-15 | | thegoodanarchist: <morfishine: Great finish by Karpov. I was thinking this was that great game vs Topalov Karpov vs Topalov, 1994 But then realized this was a different game> Thanks for the link - ouch for Topa, the loser in at least two immortal games, the other beat down from Kasparov: Kasparov vs Topalov, 1999
Maybe someone can find a spectacular beating of Topa by either Kramnik or Anand, or both, and then dub them "so and so's immortal" to heap more ignominy upon the Bulgarian GM. |

 | | Penguincw: 27.Rxe6 was obvious, but that's the only ply I got.
< Maybe someone can find a spectacular beating of Topa by either Kramnik or Anand, or both, and then dub them "so and so's immortal" to heap more ignominy upon the Bulgarian GM. > Hate to go against my favourite player, but here's one great game by Kramnik: a king walk done <blindfolded>. Kramnik vs Topalov, 2003
As for Anand, a couple of games come to my mind right away: Anand vs Topalov, 2010 (G4) I remember when I first saw this game, I kept constantly reviewing it over and over. Topalov vs Anand, 2010 Game that clinched Anand his title. Anand vs Topalov, 2005 A spectacular draw by the 2 players. Topalov vs Anand, 2005 Again, not a win by Anand, but he was able to hold Topalov to a draw despite being up in a queen ending 2 (split) pawns to zero. If Topalov had won the game, he would've started 7/7. Instead, it was "only" 6.5/7. |
|
| Jul-25-15 | | CHESSTTCAMPS: White has 2 pawns+N+B for a bishop pair, but black threatens Qxa6, Qxa2 and Kxe7. On the other hand, white's majors are lined up vertically towards the black king position (much stronger than the black counterparts), suggesting a breakthrough sac on e6. 27.Rxe6! gives white a quick path to victory after direct acceptance: A) 27... fxe6? 28.Qxe6 Bxb2+ (Qxa6? 29.Qf7+ Kd7 30.e8=Q#) 29.Kd1! and black has no defense to the threat Qf7+ followed by mate. B) 27... Qxa6 28.Qf4! Qxf1+ (fxe6+? 29.Qf7+ etc) 29.Qxf1 fxe6 30.g6! Bxb2+ (Kxe7 31.Qf7+ Kd8 32.Qxg7 Re8 33.Kd2 (not Nd2?? Re1#) is a winning endgame. C) 27... Qxa2 28.Rxd6 Qxb2+ (or Bxb2+) 29.Kd2 - the white king is safe and white is a piece up with the threat of 30.Bb5+ forcing mate. All I have time for - time for review. |
|
| Jul-25-15 | | CHESSTTCAMPS: I also considered 28.Rxf7 in line B, but didn't work it through correctly. |

Probably because after 28.Kxb2 fxe6 29.Qf2, aiming at a7 and f7, Black looks defenseless.> 27...Bxb2+ does look like Black's best try. After 28. Kxb2 fxe6 29. Qf2 Qe5+ 30. Kc1 Kd7 31. Qa7+ Kc6 Black is barely alive, but can still hope for a tactical error.
