Play g4 and g5 first (before h4 and h5) to save time, especially if black plays Qa5 in the opening.

<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.

I still feel that the moves of <Ne1> then <Ng2> for white hold a lot of potential in this line. Mind you in our game the black king didn't go to g8. But still I feel there is potential in the knight going to the g2 square.

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.

  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
Premium Chessgames Member
  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
Premium Chessgames Member
  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

  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.

Jul-24-11  capafan: <blue wave>

If you read between the lines in Black's analyses, we considered playing b4 at almost every move from move 15 on...it even advanced to the stage of a joke. <AK> kept track of the number of engine lines containing the move b4 until, as <Tabanus> says, the sword of Damokles finally came down. However, at the point b4 was played it was anticlamactic being less of a sword and more of a pen-knife. It was only after continually analyzing b4 do I come to the conclusion that its bark is worse than its bite. :)

I have mixed feelings about the Black side of the McCutcheon as I believe there is still much to learn; but playing white against the McCutcheon, I might tend to be more, rather than less, aggressive (definitely if playing OTB rather than CC)... along the lines <YouRang> and <cro777> suggest. The WKR seems to be a more effective offensive rather than defensive piece. In addition, in many lines whereby Black chooses to play g6 rather than f6, the h-pawn becomes a terrible liability as it cannot be defended by either the BN or BB. Playing Black, I would search for a better placement of the BQN and BQB in the opening...it is amazing given the structure of the position, White cannot exploit the immobility of either Black minor piece. <AK> had some interesting ideas early on of playing Bd7..Bc6..Nd7; however this does not always work as <YouRang> demonstrated...so the search for improvements will go on despite our struggle here.
