| May-13-11 | | tacticalmonster: I had 29 e5, 30 Bxh7,31 Rxe5 dxe5 ,33 Ne4 but somehow I threw in the dumb move 32 Bxh4?? and convinced myself of a forced win. The more natural sequence is 32 Ne4 Kg7 33 Bxc5 Nxc5 34 Qf2  and white had a strong attack and it more than compensated for the pawn minus. No credit for me today. It has been a tough week. |

 | | takchess: In yesterday's puzzle of the day, <Sneaky> kindly commented on the use of this sites SJKbase Java viewer and the ability to move the pieces around. In playing around with it, I also learned it has a Quiz mode (click on the Question Mark). This is very cool as it hides the next move from the table and can be used with Solitaire Chess or following past game connections such as Phony Benoni Puzzles of the Day without tipping the answer to the puzzle. I figure it's worth sharing as I have been visiting this site for a number of years and just figured this out yesterday. Perhaps others are in the same boat. |

| May-13-11 | | sevenseaman: I've tried to piece together <Ghuzaltyy>'s analysis. I believe the gist is this; <29. e5 Rxe5 >
<30. Bxh7 Kxh7>
<31. Rxe5 dxe5>
<32. Ne4 Bxf2>
<33. Rxf2 Kg6?>
<34. Rxf6+ Rxf6>
< 35. Qxg5+ Kf7>
< 36. Qxf6+ Kg8>
< 37. Qe7!> Black cannot
avoid mate.>
click for larger viewA very nice piece of work. A slight problem occurs at Black's 30...Kxh6 move. Its not forcing. Black could better respond 30... Rxe1 and set up a chain reaction. We need to analyse afresh and see if White can carry the day. |
|
| May-13-11 | | David2009: Kramnik vs Nunn, 1994 Whie 29? White can break with 29 e5, or can prepare e5 with 29 Bxc5. The immediate 29 e5 allows 29...fxe5 and there is a treble attack on the Bf2.
But 29 Bxc5 Nxc5 30 e5 dxe5! since the Nc5 guards e4. Conclusion: 29 e5 expecting 29...fxe5 30 Bxh7 Bxf2 31 Qxg5+ Kxh7 32 Rxf2 Rxf2 33 Qxh4+ and White
has two connected passed Pawns. There are other variations to be resolved OTB but this is the general idea. The game is far from over. Time to
check:

I am on the right lines. Time to digest the kibitzes. Meanwhile, here's a link to Crrafty End Game Trainer http://www.chessvideos.tv/endgame-t...

 | | scormus: Move 29 and only one pair of p's exchanged. I looked at it for some time, trying to make something of Bxh4 and came up blank. e5 would have to be the move, vacating e4 and discovering the attack on BNh7 but I couldnt string anything together. Completely defeated :( This whole week's been tough, and theres still the weekend. |
|
| May-13-11 | | Patriot: I gave myself about 5 minutes and although I looked at 29.e5, I didn't see what happens after 29...dxe5 giving black a strong passer. I thought 29.Bxh4 gxh4 30.Qf4 looked interesting although it is very risky. The idea is to threaten both 30...e5 and 30...Qxh4. I knew this problem would require much more time to calculate. As an improving player, I'm learning to recognize whether a position is critical or not which affects how it is to be analyzed. Here, black doesn't seem to be threatening anything except the possibility of exchanging off white's DS-bishop which "could" be a key player in breaking down black's position "if" the possibility exists. It may be that black is also threatening a fortress with 29...Re5, but the threat is only real if white has a way through. In my opinion though, 29.e5 must not be played lightly. What happens after 29...dxe5 must be considered and I think <Ghuzultyy> may have hit upon the right idea. I didn't consider this. |

| May-13-11 | | Ghuzultyy: <sevenseaman: A slight problem occurs at Black's 30...Kxh7 move. Its not forcing. Black could better respond 30... Rxe1 and set up a chain reaction.> You are right, I missed that move in my analyse; time to check. <30...Rxe1!?>
Kxh7 doesn't work so; black decides to change things. 
click for larger view<31.Bxe1>
The queen and rook position is great for attack so 31.Qxe1? or Rxe1? would be a mistake. <31...Kxh7>
I couldn't see a better way to continue.
<32.Ne4!>
The move that wins in each variation!
<32...Bd4>
This variation's difference is that white doesn't have the chance to get the bishops out of the board whenever it is needed. Now black defended f6 pawn. <33.Nxg5+!>
Unfortunately for black, white's only threat was not 33.Nxf6+. This also is winning for white. Its over but let's finish the variation.
<33...Kg7 34.Nxf7 Kxf7 35.Qh6 Qb8 36.Bc3> In final position black can't defend f6. Its over.

| May-13-11 | | Ghuzultyy: The moves used against Crafty EGT:
29.e5! Rxe5 30.Bxh7 Kxh7 31.Rxe5 fxe5?! 32.Qxg5 Qb8!
Well, I didn't expect this move.
33.Ne4! Qf8 34.Qxh4+ Kg8
Well, I tried 35.Qg5+,35.Ng5,35.dxc6 and I couldn't beat yet. |
|
| May-13-11 | | kevin86: No chance-this was way above my pay grade... |
|
| May-13-11 | | Ghuzultyy: If it is this hard already, this weekend will be really tough. |

 | | HeMateMe: ...thats what I told my first girlfriend. |
|
| May-13-11 | | ReikiMaster: Bc5 is pinned which suggests 29.dxc6. The afore mentioned 29.Ne3 also gives white an advantage after Kh8 30.Bd1-h5. From a positional point of view black's kingside is compromised and black has more forces on the queenside. It is the perfect time to open the center. After 29.e5 Rxe5 30.Rxe5 dxe5 white wins as well - 31.Bxh7 Kxh7 32.Ne4 Kg7 33.Bxc5 Nxc5 34.Qf2. |
|
| May-13-11 | | sevenseaman: <Ghuzltyy> You have worked hard but you have assigned a couple of redundant moves to Black which cause him loss of tempi and help White win unfairly. As I read it, this is your line; <29. e5 Rxe5
30. Bxh7 Rxe1
31. Bxe1 Kxh7
32. Ne4 Bd4*
33. Nxg5 Kg7
34. Nxf7 Kxf7
35. Qh6 Qb8
36. Bc3>
click for larger view<And Black can't defend f6. Its over.> But Black has better moves and if we make those we reach this; 29. e5 Rxe5
30. Bxh7 Rxe1
31. Bxe1 Kxh7
32. Ne4 kg6
click for larger viewIt would be pointless to go like this;
<33. Rxf6+ Rxf6?>
<34. Nxf6 Kxf6>
< 35. Qh6 Qb8>
< 36. Bc3>
click for larger viewWhite has little to be happy about. I think moves from 33 onwards have to be reviewed. Off hand it does not look as though White can win in this line but I will be working on it. |
|
| May-13-11 | | Ghuzultyy: <sevenseaman>,
After 32...Kg6? 33.Rxf6 is winning indeed.
33...Rxf6 34.Qxg5+! (I guess this is the move you missed, correct me if I misunderstood) 34...Kf7 35.Qxf6+ Kg8 36.Qg6+ Kf8 37.Nf6
Followings are Nh7+ Bxh5+ Qf7+ and it will be mate soon. But I still couldn't beat Crafty EGT after 31...fxe5. Any help would be great. |
|
| May-13-11 | | chesssantosh: if this is Friday imagine what would be Sunday? |
|
| May-13-11 | | David2009: <Ghuzultyy:>: I am really impressed with your analysis. <But I still couldn't beat Crafty EGT after 31...fxe5. Any help would be great.>
I gave up and consulted Fritz 6 which obliged with a winning line (32...Qb8
33.Ne4! Qf8 34.Qxh4+ Kg8 35.Ndc3!) to reach
click for larger view
and I am sure you will be able to work the rest out (starting 35...Rf4 36 Qg5+) Please email me (via my forum at User: David2009) if you want the full moves - I am leaving it there in case others want to solve it. <An Englishman: Good Evening: This is a puzzle you should not analyze. Play e4-e5, and for the price of a pawn, you gain two minor pieces, the Bc2 and Nc3 (meanwhile, Black's Queen is *where?!*}. To me, this puzzle is more a test of judgment than analysis. Just play the move and save time on your clock.> Very well put! With the one caveat that you should IMO consider whether the Bishop exchange first is needed. |

| May-13-11 | | ahmadmitto: good tactic for white !!! |
|
| May-13-11 | | KingV93: I liked 29.e5 and thought Whites LS♗ would capture the ♘h7 at some point but went with 29.♗xh4 as my choice in order to crack open the Kingside and commence the attack. Bzzzzzt! Wrong! No cigar today. |
|
| May-13-11 | | Ghuzultyy: <David2009>, I used the same line until 35.Ndc3! as you can see in my earlier post. I found a winning line in the end but this puzzle is way too hard for friday. |
|
| May-13-11 | | KingV93: p.s. Looking at the stats Kramnik does very well against the KID! His losses are to top ranked opponents almost solely; Kasparov, Leko (playing the KID?!) and Ivanchuck, all Top level players. Maybe playing this against Krammy isn't such a great idea?.... |
|
| May-13-11 | | cyclon: A very high-level players here and in my opinion very difficult position as well. It seems I'm late all along this week, so just one line which can be way off the base; 29.Bxh4 gxh4 30.e5 dxe5 31.Bxh7 Kxh7 32.Re4 Bf8 33.Rxh4+ Kg8 (-Kg6 34.Qe2 Rh7 [-f5??] 35.Rxh7 Kxh7 36.Qh5+ >37.Ne4, xf6) 34.Ne4 and if -Bg7 ( -Be7 35.d6) 35.Nd6. |
|
| May-13-11 | | LIFE Master AJ: I actually got the key move almost instantly.
BUT ... finding all 15 moves?!?!???
Insane, that would make it a Sunday puzzle. |
|
| May-13-11 | | WhiteRook48: well, I got 29 e5 rather easily. Finding everything is harder than a Sunday puzzle. |
|
| May-13-11 | | patzer2: Kramnik's positional clearance sacrifice 29. e5! solves today's difficult Friday puzzle. Seeing the positional idea of pitching a pawn to increase the mobility and the scope of the White pieces in attacking the Black King wasn't too difficult. However, the complications involved in the followup make this an extremely difficult puzzle, especially if you are trying to analyze it for a forced win. Indeed, it's not clear that Kramnik or Nunn found the best moves in the followup. For example, better than 32. Qxg5 where Black missed 32...Qb8!  with practical drawing chances, is the Fritz recommendation 32. Qe2! when play might continue 32...Kg8 33. Bxc5 Rxf1+ 34. Qxf1 Nxc5 35. b4 Na4 36. Qf6 Qd4 37. Qd8+ . |
|
| May-13-11 | | TheBish: Kramnik vs Nunn, 1994 White to play (29.?) "Difficult"
No time left, but I'm going to guess the first move is 29. e5!, sacking a pawn to open up the diagonal for the bishop. |
