 | | kevin86: Pshaw! I looked at every sacrifice move but this one-starting with the Marshall clone Qg3. BTW,I saw a neat helpmate in two by:34...♖f2 35 ♔xf2 ♕e3#} Of course ♖f2 is met by 35 ♖xf2 ♕e1+ 36 ♖f1 ♕e3+ 37 ♔h1 and escapes the checks. I the text if 36 ♖f2 ♕xe3 37 ♕f7 ♖e1# taking advantage of the pin. |

| Aug-23-07 | | MostlyAverageJoe: <znprdx: 34.Qe4!! after moving or protecting the Bishop the threat is Nh4. The icing on the cake is 35.Bd1 Ne3! - there I found it :) 36. Bf3 Rb1!> Hmm, maybe I am misreading your line, but 34...Qe4 35.Bd1 Ne3 36.Bf3 Rb1 is refuted by 37.Bxe4+ which wins for white (without a check on BxQ, this indeed would be a winning position for the black). BTW, I did not use software on this puzzle (it is busy running Fritz for the 5.? move for the GMT game). If I did, I'd see RV's line <34...Qe4 35.Bd1 Nh4 36.Bf3 Qg6 37.Bxd5> diverging on the 37th move from my "forced" < 34...Qe4 35.Bd1 Nh4 36. Bf3 Qg6 37.Kh1> <tallinn: ... one does not learn anything from computer lines that improves chess skills. They are just useful to indicate errors in own calculations that would be missed otherwise> Depends on what you do with the analysis. I always ask myself "what would I have to look for in order to find the same solution?" This sometimes generates useful insights. For short tactical shots, software cannot be beat. But yes, it will miss long-term strategies, as well as winning sacrifices that are not recovered very quickly. In complex positions, one still has to use software as more than just a push-button solution provider. The multi-variant lines done with shallow (20 plies or less) analysis generally cannot be trusted past the first 6-8 plies. They have to be augmented with sliding forward/backward analysis (which I normally do when I post "best for both sides" lines). The software is still just a tool, and it does require some skill in using it. Personally, I feel I have barely started to understand how to use software effectively... |

| Aug-23-07 | | newton296: 4 for 4 woo hoo !
this seemed so easy . mate threats or a loss of material are unavoidable after ne3 ! As soon as I saw the puzzle ne3 jumped out at me. also considered Nh4 but didnt see any good lines , so checked game. didn't look at all the silly computer lines posted. especially the ones where white blocks the rook to avoid mate with Bc2? and Q c2?? why not just resign if that's all white has. only a computer would invest thought in such a hopeless moves. |
|
| Aug-23-07 | | TimothyFoster: Please explain to me:
Why give up after losing only one pawn? Didn't he still have more material and a reasonably attacking position. Wasn't there a way to (at least) draw the game? |
|
| Aug-23-07 | | euripides: <tim> white is getting checkmated e.g. 36.Rf2 Rb1+ 37.Rf1 Qxe3+ 38.Kh1 Rxf1 mate or 36.g3 Qxe3+ 37.Kh1 Qe4+ etc. |
|

 | | fm avari viraf: My intuition says 34...Ne3 since 35.fxe3 then ...Qg5  [ even 35...Qxe3+ 36.Kh1 Qe4 threatening mate on g2 & Qxa4 is possible but inferior to the text. ] But if White declines the Knight & plays 35.Re1 then simply ...Ng4! with multiple threats should win. |
|
| Aug-23-07 | | OwenNG: I looked at Nf3 but was put off by 35 Re1, but looking again I see that 35...Nc2 would quickly end things. |

| Aug-23-07 | | RandomVisitor: <tallinn><And in all cases one does not learn anything from computer lines that improves chess skills.>I have to respectfully disagree. The computer lines are an estimate of best play, just like that of any other person who comes to this site and offers his opinion. The effectiveness of the machine estimate depends on the type of position and the length of time that the computer spends on the position. The correct way to interpret a computer line is as a suggestion, and the depth of the search in ply or half-moves should indicate roughly how much time was used in creating the estimate. The grandmasters in these games are also offering their estimate of the best move, and even they are sometimes wrong. By looking at all available estimates for the best moves, including those made by a computer, we can obtain understanding and insight into the position offered as the daily puzzle. |

1...♘e3
2.fe ♕g5(Δ ♕g2#)
3.♖f2 ♖b1
4.♖f1 ♕e3 and mate next move |

| Aug-23-07 | | Marmot PFL: You just have to make yourself analyse every threat or capture, which today for some reason I did not do. Nice example of piece coordination in an attack on a castled king. |

| Aug-24-07 | | kfkcapa2001: <kevin86>True that <34...♖xf2 35.♖xf2,♕e1+ 36.♖f1,♕e3+ 37.♔h1 and escapes the checks>. . . but not how you might expect: a plausable line may go 37...♕e2 38.♖c1,♘e3 39.♖g1,♘g4 40.h3,♘f2+ 41.♔h2,♕e5+ 42.g3,♕f5 43.g4,♕f4+ 44.♔g2,♘e4 45.♕c7,e5 46.♕c2,♕g3+ 47.♔f1,♕f3+ 48.♔e1,♕e3+ 49.♔f3,♕f3+ with perpetual. Instead of 43.g4, the exquisite 43.♖g2! seals Black's fate. Incidentally, <tallinn> might take note that 43.♖g2! here was found by a computer. And though I've found great master moves missed by computers also, these silicon thinkers do help us see things from fresh vantage points. A cool position; it's interesting how many motifs lurk inside. Too bad Razuvaev didn't defend stronger. |

 | | Honza Cervenka: <But if White declines the Knight & plays 35.Re1 then simply ...Ng4! with multiple threats should win.> Correct and very elegant but 35...Qe4 would be possible as well, for example 36.f3 Rxg2+ 36.Kh1 Qxf3 with mate. |

| Aug-24-07 | | patzer2: The Thursday, Aug 23,2007 puzzle solution
was the little demolition combination 34...Ne3!! After 35. fxe3 Qg5! 36. g3 (36. Rf2 Rb1+  ), Black wins with 36...Qxe3+ 37. Kh1 Qe4+ 38. Kg1 Qg2#. |

Thanks! |

| Sep-06-07 | | kfkcapa2001: <zb2cr: "I decided that 34...♕e4 had to be it even though it did not seem to be particularly forcing after 35.♗d1,♘h4 36.♗f3,♘xf3+..."> 34...♕e4 is quite forcing (though 34...♘e3 is more so). But Black must continue not 36...♘xf3+(premature) but rather 36...♕g6 37.♔h1,♖xf2! Then after 38.♖g1,♘xf3 39.gxf3,♕f6 40.♖g3 (40.f4, nets Black a rook after ...♕b2 41.♖xg7+,♕xg7 42.♕xg7+,♔xg7 43.a4,♖xd4 and mops up the q-side pawns), 40...♕a1+ 41.♖g1,♖f1 42.♕xg7+,♕xg7 43.♖xf1,d4with a whopping Q vs. R advantage for Black. Note that the Black queen makes half the moves. Its precise play joined to the crackling ...♖xf2 shot busts the underdefended White kingside, all because the White queen is cut off from the scene of action. A fine position to linger over--with more than one way to win. |
