click for larger viewI was going crazy seeing our rook placed on h7 during the course of our game & it happened in many of the computer generated lines. Sometimes I would wonder how these engines could ever beat humans when they might allow such moves(...Rh7) to take place. We may as well put a 'toe tag' on that rook(h7) that says R.I.P.. The move 23...Qf8?! helps seal the rook's coffin(23...bxa3 seems somewhat better). The possibility of scenarios such as this is one of the main reasons why our team finally decided placing the king on g8 might not be considered a best course of action. Another factor was the potential 'hole' created on f6 after black's move ...g6 that might be used against us. I get the 'willies' every time I see a position such as the one above. |

| Jul-22-11 | | cro777: <chesstoplay: < chrisowen > was Team White's secret weapon...he always generated ideas no matter the position.> Here is one of his ideas. After <17.h5> Team White expected <17...Kg8> keeping the black king on the kingside. Instead we played 17...Qe7 followed by 18...Ke8 to avoid beeing the target of a kingside onslaut like the one in the following <chrisowen>'s winning (?) line after <17...Kg8 18.g4 Qe7> <chrisowen: Is there a win?

|
| Jul-22-11 | | WinKing: Just out of curiosity <cro777> can black get away with <28...Rxh6?!>
instead of your <28...Rb6>? I know the e6 square is critical & must be defended by black. Something like this maybe:

click for larger viewThe line I show above was Rybka 3 at d=20. So I'm assuming your move <28...Rb6> was obtained at a deeper depth. The above seems like it will be drawn but is not nearly as attractive as your line. |

<May-22-11
blue wave: btw I've based my analysis on the common theme moves of <16...Rb8>
Rybka 29 Ply - <17.g4 Qe7 18.h5 Kg8> Pretty likely. Of course I could be wrong but nice moves all round.Rybka 22 Ply - <19.Qe3 g5> I like Qe3, I like the solid feel of this move. Defends c3, d4 & e5. But I'm intrigued at to why Rybka and Hiarcs push the g pawn to g5? I don't really understand why? Why does black lash out like this? Is black starting to feel some pressure? Or is it simply because white can no longer play Qf6 after moving to e3? Still, I think the move g5 can create a weaker pawn structure around the black king and give white the opportunity to place the rooks in attack on the h file. At this point I felt it worth looking at the move <20.hxg6EP fxg6> Black has no other option as I can see? Now at this point white has to try to get in f4 as far as I can see? Blacks going to mount pressure on the f file. So white responds with <<<<21.Ne1>>> Qf7 22. f4 Kg7> The black rooks really need to get in touch with each other and this move strengthens the weak pawns a little. I have wondered if moving the king to g7 is a mistake here for black? Maybe it should be getting out and going to e7? <23.Ng2> White is now ready to switch to a kingside attack. Whites f pawn is well protected by the knight. The h file looks attractive for an attack with rooks. Analysis provided provided by haircs13.2mp - 23 ply

| Jul-23-11 | | capafan: In some games, it is easy to judge in hindsight alternatives that could have been played and resulting positions; however, there is a reason this variation is still a mystery. Both sides, it seems, have resources the chess engines do not fully understand. I dare say both teams could replay the game seeking not to overlook the same opportunities and yet not reach a better result. <chrisowen>Your commentary is reminiscent of an author I much admire and one whose one book in particular I have read (and reread) many times...James Joyce, "Finnegan's Wake". You both may share a common goal in your writing. |

| Jul-23-11 | | cro777: THE PUZZLE OF THE DAY - WHAT IS THE RATIONALE BEHIND 16.Rhb1?
click for larger view
<16.Rhb1>
THE ANSWER
<imag>: "We may want to play 15.a3 to play <16.Rhb1> next... then <b4> is stopped for the moment (Black may still play it, but it is not very effective) and we may proceed with <h5/g4>. <cornflake>: " Then in some sequence of moves <h5,g4,Qe3,Nh4,and f4>. That's the general scheme of play but the move order depends on what black does. Eventually after breaking through kingside we bring the rooks back kingside". <David2009>: "16.Rhb1 is very defensive, and is well met by 16...Ne7. I once again propose <16.Nh2> intending <Bh5> followed by <Ng4>". EPILOGUE
<capafan>: "I am still trying to understand the rationale behind <16.Rhb1>" cro777: "Realizing you don't know is often as important as getting the answer". <capafan>: "I feel very "important" right now". |
|
| Jul-23-11 | | WinKing: I remember thinking the move <16.Rhb1> was an inaccuracy on white's part. Figured the rooks might be better placed on the kingside in support of the g & h pawn(s) advances. All the engines seemed to love it though. |
|
| Jul-23-11 | | blue wave: <capafan><THE PUZZLE OF THE DAY - WHAT IS THE RATIONALE BEHIND 16.Rhb1?> OK.
Here are some patzer thoughts.
b4 is coming too quickly for white.
Our king is at d2.
The exchange of pawns after b4 leaves our king exposed.
White needs some more time to advance the g and h pawns. |
|
| Jul-23-11 | | blue wave: <HOW WOULD BLACK PLAY AFTER <14.g4 and 15.g5>? I suppose black would play Qe7 still and Ke8? |

| Jul-23-11 | | blue wave: <capafan><THE PUZZLE OF THE DAY - WHAT IS THE RATIONALE BEHIND 16.Rhb1?> "FEAR" of b4 and losing. |
|
| Jul-24-11 | | blue wave: I think after the last team game where we played the RISKY g4 as white and lost. I was less inclined to take any risks. So in choosing between <Rhb1> and <g4> I went for what I felt was the safer option. I was in no mood for another lost game. So I think you could say that psychology played a part for me. I suppose in any series of games, previous loses can affect how one continues to play after the lose. |

| Jul-24-11 | | capafan: <cro777>
<capafan><THE PUZZLE OF THE DAY - WHAT IS THE RATIONALE BEHIND 16.Rhb1?> <16.g4 b4 17.h5 bxc3+ 18.Kxc3 > I would argue that the "threat" of b4 in most instances (e.g. <bluewave>'s response) in this line is more dangerous than its implementation. After Black plays b4 the threat no longer exists and despite the initial eval, White is less at risk not more. Black's Queen may be lured away from defense on the kingside but I am unsure (Q.E.D.) that Black can obtain anything of lasting value. As shown in the game, on a long-term basis, White cannot effectively prevent (only deter b4) by Rhb1 or any other move. This was my original point. Given this, either White chooses to be aggressive and pursue the kingside push or hope that Black makes an error...which in CC play is unlikely at a high level. |
|
| Jul-24-11 | | cro777: <blue wave> I agree completely with <capafan>. That was our original point. In the most recent (2010) CC game Thomas Rattinger (2509) played 16.Qe3. We also analyzed 16.g4 and 16.h5. In certain variations <Rhb1> might be necessary later if Black played <...b4>, for instance 16.h5 b4 17.axb4 axb4 18.Rhb1 |

| Jul-24-11 | | cro777: <chrisowen> In 2008, Chessgames helped a research study on chess aeshetics for University of Malaya (Kuala Lumpur, Malaysia). This survey and its results were further analyzed and used as part of a computational study of aesthetics in chess. The survey was intended to gauge human player aesthetic assessment of direct mate-in-3 combinations. Tournament games between expert players and compositions were used in varying mixtures. Respondents were asked to rate them between 1 and 10 based on beauty. Here is the combination with the highest estimated value (8.1):

1.Qd6+ Kxd6 2.e8N+ Kd5 3.Nc7#
It is easy for computers to find the solution. But to conceive something like that, much more is needed. Your lines in this game might be candidates for a simillar research. |

<I would argue that the "threat" of b4 in most instances (e.g. <bluewave>'s response) in this line is more dangerous than its implementation.>I think your right in hindsight.
Some in our team were not happy with 16.Rhb1, and I'm starting to understand why now. Thanks for your keen insight.
Cheers Blue Wave. |
