| Oct-02-15 | | ColeTrane: 29. Kh1 !! |
|
| Oct-02-15 | | diagonalley: hmmm... the first three moves stand out, but a fair bit of calculation remains before the sacrifice can be justified... one wonders how far ahead judit saw... very impressive nonetheless |
|
| Oct-02-15 | | Al2009: Not so difficult, indeed... |
|
| Oct-02-15 | | morfishine: I got it, all the way up to the very first move <25.Rxg7> ***** |
|
Oct-02-15
 | | scormus: ColeTrane, Kh1 yes! The silent assassin |
|
| Oct-02-15 | | blessingmandindi: I just cant believe it. I am always solving up to two and a half stars but yesterday's two and a half stars I failed but today I just managed to solve three stars. That is progress for me I guess, in a weird way though. |
|
| Oct-02-15 | | gofer: I look at this and I see lots of possible paths;
25 Qd7 ...
25 Qh3 ...
25 Nd1 ...
But one stands out as being very forcing...
<25 Rxg7 Kxg7>
<26 Qh6+ ...>
26 ... Kh8
27 g6 
26 ... Kg8
27 g6 hxg6
28 Qxg6+ Kh8
29 Kh1!
<26 ... Kf7>
<27 Rb1! ...>
So the only question is whether black has recently
played Qxb2 - winning a pawn and losing the game!
~~~
<Al Wazir> 27...Rf6 ? 
click for larger view28 Qxh7+ Kf8
29 g7+ mating
~~~
To all those that are saying <29 Kh1> "Doesn't this need a lot of calculation?"... 
click for larger viewThis is pretty standard stuff. Rf8 must move to stop the immediate mate threat... 30 Qh6+ Kg8
31 Rg1+ Kf7
32 Rg7+ Ke8
33 Qe6+ mating
The only chance for a defence is <29 ... Rf4> hoping to play Rg4 if Ph5
is still on the board Judit cooly shows that this doesn't work! ~~~
<diagonalley: one wonders how far ahead judit saw> I imagine it was approximately around here! When she sacrifices Bd2 + two pawns to displace the black queen and get a rook on the 7th! Gambling on
black's greed...
Beautiful play...

| Oct-02-15 | | Cybe: al wazir: Where's the win after 27...Rf6 ?
Don't be lazy, Wazir: 28. Q:h7+, 28... Kf8, 29. g7+, etc. |
|
| Oct-02-15 | | whiteshark: My solution has been <25.Rb1 Qxc3 26.Rxg7 Kxg7 27.Qh6+ Kf7 28.Rxb7+ Ke8 29.Qe6+ Kd8 30.Qd7#> I wonder where's the hole in it? |
|
| Oct-02-15 | | wooden nickel: It's hard to resist not sacking the quali here, although it's almost a shame to sac such a beautiful rook and many lines just lead to a perpetual check! I missed 2 important key moves before viewing with the computer.
1) 26.Qh6 Qf7 and then 27.Rb1! and not 27.Qxh7+
2) Judit's move 29.Kh1 and not 29.Qxh5+
Nice Friday puzzle! |
|
| Oct-02-15 | | CHESSTTCAMPS: White has a knight for a bishop plus two weak pawns, but the infiltration of white's major pieces into black's camp shows that white is zeroing in on the king. A forcing move to eliminate a defender is the obvious choice: 25.Rxg7! threatens 26.Qh6 forcing mate.
A) 25... Qxc3 26.Qh6 1-0
B) 25... Rg8 26.Rxh7+ Kxh7 27.Qh6#
C) 25... Kxg7 26.Rb1! (Qxe5+ was my first choice when I saw the problem) Qxb1+ (Rae8 27.Qh6+ K moves 28.Rxb2) 27.Nxb1 Rae8 28.Qh6+ Kg8 29.Nc3 followed by the maneuver Nd1-e3-f5 should be decisive. C1) 26... Qxf3 27.Rxb7+ Kh8 28.Qh6 forces mate.
Time for review... |
|
| Oct-02-15 | | CHESSTTCAMPS: Ouch - missed 26.Rb1?? Qxf2+. Not alone, it appears. |
|
| Oct-02-15 | | whiteshark: Yeah, great minds think alike... ;) |
|
| Oct-02-15 | | patzer2: <whiteshark> My failed Friday solution was also 25. Rb1??, seeing essentially the same mirage of mate you envisioned. However, Fritz quickly busts our bubble with 25...Qxf2+! which allows Black mate-in-six to follow after 26. Kh1 Qh4+ 27. Kg1 Qg3+ 28. Kh1 Rf2 27. Kg1 Qg3+ 28. Kh1 Rf2 29. Rd8+ Rxd8 30. Qe8+ Rxe8 31. Rxb7 Qg2#. In the follow-up, if Black had played 26...Kf7 (diagram below) 
click for larger viewthen 27. Rb1! would have won due to the threat 27... Qxc3 28. Rxb7+ Ke8 29. Qe6+ Kd8 30. Qd7#. According to Fritz, <23...gxh5?> was Black's decisive mistake. Instead the silicon monster indicates Black can force a difficult draw with 23...Rf7! when play might continue 24. Rxf7 (24. Qxe6 Raf8 25. hxg6 hxg6 26. Rxf7 Rxf7 27. Qxg6 Qb3 28. Nd5! Qf3 (not 28... cxd5? 29. Qe6! Qxa4 30. g6  ) 29. Qe6 Kh8 30. g6 Rf8 31. Ne3 Rf4 32. Nf5 Qg4+ 33. Kh2 Qh5+ 34. Kg2 Qf3+
35. Kg1 Qg4+ 36. Kh2 Qh5+ 37. Kg2 Qf3+ 38. Kh2 Qh5+ = with a draw by repetition. Earlier, instead of <15...Nfd7?>, Fritz indicates Black could have grabbed and held the advantage with 15... Nfxe4 when play might continue 16. Be3 Nd6 17. Ra3 Nf5 18. Rb3 Qa7 19. Bxc5 Qxc5 20. Rxb7 Nd6 21. Rc7 e4 22. Qg4 O-O 23. c3 Rad8 24. Re7 h5 25. gxh6 Bxh6 26. Kh1 Rfe8 27. Rxe8+ Rxe8 28. h4 Re5 29. Qh3 Kf8 30. Kg2 Rd5 31. h5 gxh5 32. Rh1 Bf4 33. Qh4 Rg5+ 34. Kf1 Qe5 35. Rg1 Rf5 36. Qd8+ Ne8 37. Rh1 Kg7 38. Qb6 Nf6  (-1.24 @ 22 depth, Deep Fritz 14). P.S.: <whiteshark> Our comments are transposed because this "great mind" had to repost to correct an error :) |
|
| Oct-02-15 | | AvidChessMan: I got it up to 27. g6. Good game. |
|
| Oct-02-15 | | kevin86: Great finish! Figured only the first few moves... |

 | | Jimfromprovidence: <gofer> <To all those that are saying <29 Kh1> "Doesn't this need a lot of calculation?"... This is pretty standard stuff. Rf8 must move to stop the immediate mate threat...> Black can also try 29...Qb3?!, looking at 30...Qf7.
click for larger viewThis line below still works, winning the queen for a rook. 30 Qh6+ Kg8
31 Rg1+ Kf7
32 Rg7+ Ke8
There is something even better, however. It begins
30 Qxh5+ Kg7 31 Rg1+ Kf6 32 Nd5+!

| Oct-02-15 | | saturn2: I feel rather happy to have dismissed finally Rb1, but have to admit it was rather long on my mind. So I saw Rxg7 followed by Qh6, and had the idea of an possible mate with Rock and Queen on the g and h file. Definitely I would have played Qxh5 earlier. I am contend with 1/2 point. Its not a full point because I should have seen concretely the mate or winning of the rock a8, otherwise Rxg7 is a bit speculative. |
|
| Oct-02-15 | | agb2002: White has a knight for a bishop and two pawns.
Black threatens Qxc3.
The first idea that comes to mind is the maneuver 25.Rxg7 Kxg7 (25... Qxc3 26.Qh6 and mate in three) 26.Rd1 but f2 becomes undefended, allowing 26... Qxf2+. Another idea is 25.Rxg7 Kxg7 26.Qh6+
A) 26... Kf7 27.Rd1
A.1) 27... Rad8 27.Qf6+ Kg8 (27... Ke8 28.Qe6#) 28.Rxd8 A.1.a) 28... Rxd8 29.Qxd8+ Kf(g)7 30.Qf6+ followed by 31.Qxe5 + - [N vs P]. A.1.b) 28... Qxc3 29.Q(R)xf8#.
A.1.c) 28... Qa1+ 29.Kg2 solves nothing for Black.
A.2) 27... Rfd8 28.Qf6+ Ke8 (28... Kg8 29.Rxd8+ transposes to A.1.a) 29.Qxe5+ Kf7(8) 30.Qf6+ Ke8 31.Rb1 (31.Qh8+ Ke7 32.Nd5+ Rxd5 33.Qxb2 Rxd1+ unclear) 31... Qd2 32.Rxb2 Rd7 33.Rxd7 Qxd7 34.Qh8+ Ke7 35.Qxa8 + - [N]. White can also grab the pawn on h7, with check, at least. A.3) 27... Qxc3 28.Rd7+ and mate next.
B) 26... Kg8 27.g6 hxg6 28.Qxg6+ Kh8 29.Kh1
B.1) 29... Rg8 30.Qh6#.
B.2) 29... Qxc3 30.Qh6+ Kg8 31.Rg1+ Kf7 32.Rg7+ Ke8 33.Qe6+ Kd8 34.Qd7#. B.3) 29... Rfb(c,d,e)8 30.Qh6+ Kg8 31.Rg1+ and mate in two. C) 26... Kh8 27.g6 wins (27... Rf7 28.gxf7 Qxc3 29.f8=Q(R)+ Rxf8 30.Qxf8#). |

| Oct-02-15 | | PJs Studio: I couldn't decide between 25. Qe7? and 25. Rxg7!! because after 25. Qe7 Rg8 26. Nd1! (e3-f5) I thought white had a bit of a choke hold. Plus, my calculations after 25. Rg7!! Kxg7 26.Qh6+ ran afoul to so many different king moves - all requiring a bit of calculation. Damn. So I'm not as good as Judit!

 | | GoldenKnight: This one is fairly easy. You can see that all you need to do is open the attacking lines, thus, the R sac is obvious. The the Q check followed by the pawn move are straightforward. From there, all you need to realize is that the K move to h1 at some point completely opens the lines and Black is done. After that brief analysis, I played over the line and saw every move that was coming up to the point where Black played ... Rf4. but by then it was over anyway. |

| Oct-02-15 | | mikrohaus: Judit plays an elegant style of chess. [Is she retired again?] My brain came up with paralysis (Qe7) by threatening mate on g7, bringing the N over (via e3, after attacking the BQ), and make my opponent think it's time to quit. Judit's way is very beautiful and concise, but I would win as well, I think, although a computer might find a save. In real OTB, Black is dead. So, it's a great game by a famous GM against another famous GM with great precision. [Did anybody notice the scary stuff Bareev was brewing in Judit's line?] That's why I would, as a practical player, never play the rook sac against Bareev, but the crush. If I have a GM struggling, I don't go for pretty, but instead, effective moves. That's why I think Qe7 is also an answer; whereas, Judit's way is beautiful, but complicated. Many of us, who are very good players, would blow it in Judit's line, because of nerves and Bareev's counter-chances causing us to go into "panic-mode" (which GMs get away with a lot, because we believe them, a GM, and not ourselves.) My only point: Qe7 forces passivity from Black. Then you attack the BQ, get your N to e3 and beyond, and resignation will follow OTB. I don't have the best engines to test this completely (computer-analysis-wise), but I think it's very practical |
|
| Oct-02-15 | | The Kings Domain: Interesting sacrifice by Polgar but I don't see mate on the final position. Did Bareev run into time trouble? |
|

 | | JointheArmy: Judit is incredibly underrated. This attack was worthy of Kasparov. |

Oct-03-15
 | | Penguincw: Doesn't seem too hard of a Saturday puzzle. I got 25.Rxg7+ Kxf7 26.Qh6+ Kg8, thought about it a bit, and then came up with 27.g6 hxg6 28.Qxg6+ Kh8. OTB, I'd probably take the perpetual check. Wait, is this Friday's puzzle? I thought it was Saturday's puzzle! |
