|
| Apr-13-07 | | Justawoodpusher: My first Friday puzzle where I found the solution (at least I saw it through till move 29 and considered it winning). So bad I missed yesterday when I found the moves but had the wrong order! |
|
| Apr-13-07 | | MostlyAverageJoe: <alfilbueno: <Bingat29> There is a "hole" in your line, after 32 Bh4+? Ke5! and there is no mate>
Not only there is no mate, but black easily wins. This deserves two question marks: 32 Bh4+?? <Marco65: 31.Bf6 seems faster (31...Kh5 32.h3 Qxd5+ 33.Ke1)> Good find. However, in your line, black can delay the mate thus: 33 .. Qd1+ 34 Kxd1 Be2+ 35. Kxe2 (any) 36. Rh8# Here's a faster way:
31. Bf6 Kh5 32. Rh8+ Kg4 33.Rh4+ Kf5 34. Rf4#
However, the line above relies on the bad move 31 ... Kh5?. Instead, black could do: 31. Bf6 Qxd5+ 32. Ke1 Qg8 33. Rfxg8 Kh5 34. h3 Bc4 35. Rh8# but I think this is all, and it does win faster than the line played in the game. |

Nothing sweet there. Black reciprocated with another blunder. This has been all analyzed earlier. <YouRang: BTW, the other really impressive move was 33. Rh5+!! (if 33...gxh5 34. Rg5#).
If white saw this at move 26, and he probably did> I doubt he did. Had black played 30 ... Qxd5, the game would be much longer. |

| Apr-13-07 | | realbrob: I got the first 3 moves, so maybe I can't say I completely solved it, but indeed I found the right idea, considering I could look at the position only for some minutes. |
|
| Apr-13-07 | | alshatranji: I don't think this was easy. I saw the first three moves, but I din't see the mate with the rook at h8 (I was thinking about Rxf7+, which doesn't do anything of course). Better luck next time. |
|
| Apr-13-07 | | outplayer: 28.R1f7! is difficult to foresee. The sac is forced. |
|
| Apr-13-07 | | Timex: This was nice and very easy. |

 | | gawain: I just wanted to share this position which is reached after 30 Rh7+ (the right move) Kg5 31 h4+ (a tempting but terrible move!) Kg4 32 Rf4+ Kg3. Although B's king is surrounded by W's pieces there is absolutely nothing White can do to save himself from mate. The longest he can hold out is 9 more moves. Work it out! 
click for larger viewFrom here White lasts longest after 33 b3 Qa3+ 34 Bb2 Qb3. He loses faster if he tries another check 33 Be1+ Kg2. The resulting position is maybe even more amusing. The B King at g2 is completely safe.

| Apr-13-07 | | cydmd: I think White didn't see the winning move {30.Rh7+) and blundered. That move wouldn't give Black a tempo. If Black had played {30...Qb1) instead of 30...♗b5, things might be tragic for White, assuming White would follow the same "winning" line. Take a look at this: 30.♔d2 ♕b1 (threatening 31...♕d1#) 31.♖h8+ ♔g5 32.h4+ ♔f5 33.♖h5+ ♔g4 34.♖g5+ ♔xh4 and the checks are finished. So, 35.♗f6 didn't work (35...♕d1+ 36.♔c3 ♕d3#) and White is lost because of the hanging rook. Even so, 31.♖h7+ still wins.
If White tries to escape with 31.♔e2, it follows:
31...♗b5+ 32.♔d2 because if 32.♔f2 ♕f8+ and {33...Qxf8)
32...♕d6+ 33.♔c1 ♕xe3+ and Black has at least a draw. If White didn't see the winning line, Black could spend a tempo to win. I didn't check this analysis OTB so, please, feel free to make comments on it. |

| | gawain: In the second position above I meant to refer to the K at h2 not g2. This K plays a role in B's mating attack. Here is one likely mating position that can arise from the previous diagram. After 39 ...Bb5#

|
| Apr-13-07 | | MostlyAverageJoe: <cydmd> In your second paragraph, 33.Rh5+ is what loses it for the white. Try running away with the king instead: 33.Ke2! Black cannot prevent the white king from reaching relative safety on h2, cutting off the escape for the black king. It can still survive a bit by trading its queen for the bishop, but white wins easily. |

 | | mahmoudkubba: Apart from not understanding any think even lots of theoratically matters abt this game, I couldn't understand why bl. didn't play 30- ... qb1?? really in that I am at least just asking God's rewards and Thawabs. |
|
| Apr-13-07 | | MostlyAverageJoe: OK, so when could black save himself? HIARCS says:
After 24 ... Re7, the bishop on g7 is perfectly safe (25. Rxg4? Rf2 26. Bd2 Qa1+ 27. Kc2 Qxe1). Therefore 25. Rxf8, small advantage for white (+1), long game ahead. After 23 ... Bd7, doubling white rooks on file f leads nowhere, e.g. 24. Ref1 Ba4 and now white has no tempo for R1f7 as in the game, because of Qx2# threat. The position evaluates at +0.03 for white, virtually even. |
|
| Apr-13-07 | | ruzon: An interesting element is White's positioning of pawns a Knight's move apart on the Kingside, cutting off a lot of running room. |
|
| Apr-13-07 | | wals: Grind,grind,grind, no, it's not a chess pgm grinding out analysis, it's me grinding my teeth in frustation. |
|
| Apr-13-07 | | Crowaholic: The difficult part was finding the forced mate starting with 30. ♖h7+. The Spike engine says that after 30. ♖h7+ ♔g5 31. ♙h4+??, Black actually has a forced mate in 11 moves, so, as was mentioned, you have to get the bishop to f6, g7, h6 and back with check, assuming perfect counterplay. Another non-trivial line is 31. ♗f6+ ♔f5 32. ♗g7+ ♔g5 33. ♗h6+ ♔h5 34. ♗f4+ ♔g4 35. ♙h3# which involves both rooks, the bishop, and two pawns. So I think it is no coincidence that Kempinski saw the queen sac but not the best follow-up. The final position nicely illustrates this: White threatens ♖h7#, but Black has the momentary showstopper ♕xb2+ followed by ♗xb2 ♔xg5. Of course, being a rook for a pawn ahead, White wins the endgame easily, but probably not without promotion. |

| Apr-13-07 | | ikalel: Who saw it all the way to 33.Rh5+!?
I did OK, I saw that white shouldn't keep checking Black with Rh8+ but instead move his king. |

| Apr-13-07 | | ikalel: 30.Rh7+!! Yeah, amazing. White wins immediately. |

| Apr-13-07 | | ron11612002: This is kind of irrelevant to the topic but can anyone recommend some good chess books that I can subsitute for software. Most of you are probably grandmasters but I having a difficult time sustaining my attention and interest in chess on and off for periods of one year. At my school there's no chess clubs. I've been reading this Kasparov book and following along with the annotations. I'm analyzing more games and I do see my game improving but I just can't play at the competitive level. I have a pretty good retentive memory but i'm lacking the visuo-spatial skills. Any advice would help. Practice, repition, and hard work is the only answer for improvement and a shaper chess skills. |
|
| Apr-13-07 | | TrueBlue: I don't believe any human can see 6,7 moves ahead in this position, at least I can't see. I can't reproduce the line even after I was the solution :) Other than that I got the first 3 moves (can't calculate much than that). Maybe playing a little blind chess can help me? |
|
| Apr-13-07 | | NBZ: 30. Rh8+ misses mate by a whisker: 30. Rh8+ Kg5 31. h4+ Kf5 (Kg4? Rxg6+ Kf5 Rg5#) 32. Rf8+ Kg4 33. Rf4+ (Rxg6+ Kh5!) Kg3! (Kh5? Rh7#) 34. Rxg6+ Kh2 and the king escapes. |
|
| Apr-13-07 | | dabearsrock1010: What if 28...Qa1+? |

| Apr-13-07 | | keres777: I love 33. Rh5+...pretty move! |
