Jul-23-05  Holden: I'm looking for some help understanding 8. ... 0-0.

I've read that the idea behind 9. h3 is to keep the black bishop off of g4.

If that is the case why is 8. c3 Bg4 seldom played at club level? Why does black castle first, and allow white time to play h3? Is there a tactic that punishes 8. ... Bg4?

Jul-23-05  ughaibu: If black plays Bg4 before white has played d4 white can instead play d3 and develop the queen's knight before advancing in the centre.
Jul-24-05  Holden: Thanks, <ughaibu>. 8. c3 Bg4 9. d3 and the white queen knight will have no trouble making it to f1.

I appreciate the answer.

Jul-31-05  who: In the Zaitsev I just played an interesting (and theoretically important) variation. 9...Bb7 10.d4 Re8 11.Nbd2 Bf8 12.Nf1?! exd4 13.cxd4 Nxe4? (13...Rxe4 allows for 14.Bxf7+ and if 14...Kxf7 15.Ng5+ winning, so 13...Na5 was necessary)14.Rxe4!! Rxe4 15.Ng5 Re7 16.Qh5 h6 17.Nxf7! with all sorts of mating threats 17...Qd8? 18.Nxh6+ Kh7 19.Nf7+ Kg8 20.Qh8#
Jun-13-06  e4Newman: <9...Bb7 10.d4 Re8 11.Nbd2 Bf8 12.Nf1?! exd4>

I'd give 12...exd4?

If you want to exchange, which you don't in this line, I'd prepare with Nb8-d7 first. White has nothin' doin' but wait for black to prepare his c-pawn break.

I never thought about 12.Nf1, looks OK but there are better ways to maintain the initiative.

Sep-05-06  Albertan: Here is my analysis of a game in this variation from the 2006 59th ch Rus Chess League rd 2.

Kosteniuk,A (2534) - Inarkiev,E (2625) Opening:Ruy Lopez Flohr-Zaitsev system (Lenzerheide variation). ECO[C92] 59th ch-RUS 1st League Tomsk RUS (2), 04.09.2006

In this game GM Alexandra Kosteniuk plays GM Ernesto Inarkiev of Russia. Kosteniuk is currently the 405th highest rated chess player in the world with a rating of 2534.She is the 87th highest rated chessplayer in Russia and the highest ranked female player in Russia. Inarkiev was born in 1985 and is from the Republic of Russia. He lives in Moscow.His current elo of 2625 makes him the 88th strongest chessplayer in the world and the 21st strongest chessplayer in the republic of Russia. . He considers chess to be a sport-a martial art! He believes that an outcome of a chess game is determined by mental toughness.An interview of Inarkiev is at: http://www.chesscafe.com/text/misha... According to this website:http://www.worldchesscup2005.com/ma...: " Ernesto is one of the most talented young Russian Grand Masters. His name is connected with a sequel of victory traditions of the Russian chess school. We would like to remind that he was the European Champion U-16, Russian Champion U-20." This game was played in round one of the 59th Championship of Russia - top league.

The game began with the players playing the opening moves in the Ruy Lopez:

1.e4 e5 2.Nf3 Nc6 3.Bb5

Inarkiev now continued the game by playing:
3...a6

Morphy's idea forcing Kosteniuk to make a decision about the future of her bishop.

Sep-05-06  Albertan: The two players next made these moves in the game:

4.Ba4 Nf6

5.0-0 Be7

Completing his kingside minor piece development and preparing to castle on the kingside.

6.Re1

Finally protecting her enprise e-pawn.

6...b5

Spending a tempo to drive her bishop back further which prevents 7.Bxc6 (the delayed exchange variation).

The game continued with these moves being played:

7.Bb3 d6

The move ...d6 is a move usually played by black at this time,giving support to his e-pawn and allowing him to develop his light-squared bishop.

8.c3

The most popular continuation for White in this position. She creates an escape square for her bishop in case he plays ...Na5.

8...0-0

The most often played move by Black in this position.

9.h3

She spends a tempo to prevent him from playing ....Bg4.

9...Bb7

Developing his last minor piece and aiming it at her king. This move defines the variation of the Ruy Lopez being played:it is known as the Flohr-Zaitsev system (Lenzerheide variation). Flohr was a leading Czech-Jewish chess master of the early 20th century. He became a national hero in Czechoslovakia during the 1930s.Igor Arkadyevich Zaitsev (born May 27, 1938) is a Russian grandmaster of chess.Igor Zaitsev was Karpov's long time second, He is renowned as a very strong analyst. GM Ray Keene dubbed him a 'tactical maniac'. His system in the Ruy Lopez is a favorite of former World Chess Champion Anatoly Karpov, who used it many times in his matches with Kasparov. This system is popular because it develops the light-squared bishop with fianchetto and applies pressure to white's key e4 pawn.

Sep-05-06  Albertan: Returning to the game, Kosteniuk for her next move played:

10.d4

The main continuation for White at this time, she opens up the diagonal so she can develop her dark-squared bishop and applies more pressure to his e-pawn. Kosteniuk intends to advance her d-pawn to d5 to attack his knight and close the center very soon.

10...Re8

A move almost always played by Black at this time, he indirectly applies more pressure to her e-pawn.He intends to spend a tempo to play his bishop back to f8 (which will allow the rook to give more protection to his e-pawn).

11.Nbd2

Kosteniuk develops another minor piece, intending to transfer it immediately to f1 (so she can develop her dark-squared bishop).

11...Bf8

According to my database this is a move almost always played by Black at this stage of the game in this position.

12.d5

She spends a tempo to close the center and force his knight from the c6-outpost.

12...Nb8

This retreat is by far the most popular continuation for Black, he intends to redevelop this knight to d7. The next move in the game was:

13.Nf1

She spends another tempo to allow herself the chance to develop her dark-squared bishop,intending to move this piece again to g3 next move.

Inarkiev next played the move:

13...Nbd7

The most popular continuation for Black in this position.

Kosteniuk continued the game by playing:

14.Ng3

The most popular continuation for White in this position.

14...Nc5

According to my database Inarkive also plays the most often played move in this position for Black, forcing her to spend a tempo to move the bishop back to c2.

15.Bc2

The lost tempo. His next move in the game was:

15...c6

This move is the most popular for Black in this position. He creates the threat of 16..cxd5 17.exd5 Bxd5 winning a pawn.

16.b4

She forces him to spend a tempo to move his attacked knight.

16...Ncd7

The only move I have black playing in this position in my database, representing the lost tempo.

17.dxc6

The only move White plays in this position in my database, avoiding the loss of a pawn at the cost of giving up some of her influence in the center.

The game continued with the two players making these moves:

17...Bxc6

18.Bb3

A move almost always played by White at this time,she attacks his weak f-pawn,tieing his king down to the defense of this pawn.

His next move in the game was:

18...h6

He spends a tempo to prevent her from playing the pinning move Bg5 and in the process gives his king "luft". [Analysis:According to my database Black has also played the move 18...Nb6 in this position.]

Kosteniuk played continued the game by playing:

19.Qd3

Kosteniuk plays a rarely played continuation in my database. Her plan is to move both knights:the one on f3 to h4 and the one on g3 to h5 then move her queen first to g3 then to g6. [Analysis:The main continuation for White in this position is: 19.Nh2 with play most often continuing: 19...Nb6 20.Ng4 Nc4 21.a4 Nxg4 22.Qxg4 Bd7 23.Nf5 Kh7]

Sep-05-06  Albertan: Returning to the moves played in the game, Inarkiev's next move was: 19...Qc7

He gives some more protection to his weak backward d-pawn and in the process connects his rooks.

24...Kh8

The program Junior 9 evaluates that Kosteniuk has sufficient compensation for the knight and pawn.

25.Qxh5

This move regains her piece and creates the devastating threat of 26.Bxh6 gxh6 27.Nxh6 Re6 28.Nxf7+ Kg7 29.Bxe6 Kf6 30.Nd6 Kxe6 31.Qg6+ Nf6 32.Nxb7 Bxb7 33.Rad1 Rc8

Attacking Kosteniuk's unprotected c-pawn winning a tempo. [Analysis:Junior 9: 27...Nf6 28.Bg5 Nh7 29.Be3 Rc8 30.Rad1 g5 31.Qg3 Rxc3 32.Bb1 Nf6 with insufficient compensation for the pawn.]

Going back to the moves played in the game, Kosteniuk next played:

[Analysis:Shredder 8: 41...Kh7 42.Qh5 Nd2 43.Qf5+ Kg8 44.Rc1 Qf7 45.Qg4 Nf1+ 46.Kh1 e2 47.Qc8+ Bf8 48.Qg4+ Kh8 49.Qh4 Qc7 50.Qf6+ Bg7 51.Qxf1 exf1Q+ 52.Rxf1 e3 53.c4 Qg3 54.cxd5 Be5 55.Rf8+ Kg7 56.Kg1 Kxf8 57.Bd3 Qe1+ 58.Bf1 Qf2+ 59.Kh1 Qxf1# ]

Kosteniuk next played the move:

42.Kh1
[Analysis:Shredder 8: 42.Bd1 Qd5 43.Kg1 Qd2 44.Qxe4 Nd6 45.Qg6 Bf7 46.Qb1 Bxc3 47.h4 e2 48.Bxe2 Qd4+ 49.Rf2 Ne4 50.Kh2 Qe5+ 51.Kg1 Bd4 52.Qe1 Qf4 53.Bf3 Nxf2 54.Qxf2 Qc1+ 55.Kh2 Bxf2 56.Be2 Qf4+ 57.g3 Qxg3+ 58.Kh1 Qh3#]

Returning to the moves played in the game, for their next moves the two players played:

42...Qc7
43.Bd1??

Preventing ...d2. however this move is a blunder.

Inarkiev now found a nice idea in the position and played:

43...Qg3!

Threatening 44...Be5 which would force Kosteniuk to play 45.Qxe5 to prevent checkmate.

Sep-05-06  Albertan: These moves were played next in the game:

44.Qh5 Nd2

Attacking her rook winning a tempo. [Analysis:Shredder 8:A better idea is the pawn sacrifice 44...e2! with this variation possible: 44...e2 45.Bxe2 Ne3 46.Rg1 Kh7 47.Bxb5 Be5 which forces 48.Qxe5 Qxe5 49.Bd7 Bc4 50.g3 Qh5 51.Bg4 Nxg4 52.Kg2 Ne3+ 53.Kh2 Nf1+! 54.Rxf1 Bxf1 55.c4 Qxh3+ 56.Kg1 Qg2#]

Returning to the moves played in the game, Kosteniuk's next move in the game was:

45.Rg1

The lost tempo.

45...Bc4

Creating the threat of 46...Nf1 (which forces 47.Rxf1 due to the threat of 47...Qh2#).

These moves were next played in the game:

46.Qe8+ Kh7
47.Qd7 Qf4

He again threatens 48...Nf1 which forces 49.Rxf1.

48.Bg4 Nf1 0-1

He threatens 49...Qh2# so she resigned,as she is forced to either play 49.Qf5+ or 49. Rf1 Analysis:Shredder 8: 49.Qf5+ Qxf5 50.Bxf5+ Kg8 51.Rxf1 Bxf1 52.Be6+ Kh8 53.Bg4 Bxc3 54.Kg1 e2 55.Bxe2 Bxe2 56.Kf2 Bd3 57.Kg1 Bxb4

Mar-28-07  soughzin: Hi I have a pretty simple question and you can decide how dumb it is : ). In the closed Ruy Lopez why does white frequently play a4? Chess is often a battle for a tempo and in the positional dance of the Ruy I often see white play a4, black plays a sensible move elsewhere, later white exchanges on b5 and doesn't seem to benefit much from it.
Mar-28-07  e4Newman: <soughzin:> it depends upon the exact position. generally you're right, it costs an immediate tempo for a longer term threat. you would only use it in the closed or semi-closed positions of the ruy. it makes black ponder white's counterplay on that side. very effective in the marshall gambit for example (8.a4). rook pressure down the a-file or an attack on the black b-pawn are often possible.

i don't have the exact link but i remember a good example from one of the deep blue-kasparov games where the computer (as white) developed a beautiful, long term, winning plan down the a-file. Also, 12.a4 is a major line in the Zaitsev/Flohr. See some of the games from the Karpov-Kasparov '86 Rematch. Oh yeah, and i've used a4 as white against the archangel/moller too.

very deep, this lopez is

Mar-28-07  square dance: you're probably referring to an anti-marshall system which goes: 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 0-0 8.a4.

8.c3 would allow ...d5 and introduce the marshall attack. 8.h3 is another way to avoid the marshall attack.

  Colonel Mortimer: a4 = 1) Weaken the advanced Black Queenside 2) Open the a file for White's rooks 3) Disrupt/disuade Black's Queenside expansion 4) Exchange a wing pawn for a knight pawn giving a slight endgame advantage. 5) Avoid the Marshall 6) Constructive waiting move

  Colonel Mortimer: 7) Allow the Bishop an escape square on a2

  ganstaman: No, everyone is wrong. You push your rook pawns up in order to develop your rooks to the center of the board. Generally, it goes something like this: 1. a4 e5 2. h4 d5 3. Ra3 Bxa3 4. Rh3 Bxh3 and you get the idea. I guess black played extremely precisely here and figured out white's plan, but that doesn't happen all the time. But do notice that both of black's bishops are now on the edge of the board and under attack, so it's not so bad anyway.
Nov-17-08  Cactus: It seems that the black side of the main line Ruy Lopez is struggling of late. Perhaps a reason for the huge rise in Berlin Defence adherents?
Nov-17-08  Open Defence: well I am engaged in an interesting Zaitsev Battle and I have found IMHO that while some of the late middle games and end games arising from the well trodden paths are objectively equal, they require a very high standard of play so White has the easier game practically speaking
May-24-11  Capcom: Looking through the Opening Explorer, I noticed that the most common move order is 1 e4 e5 2 Nf3 Nc6 3 Bb5 a6 4 Ba4 Nf6 5 O-O Be7 6 Re1 b5 7 Bb3 <d6 8 c3 O-O 9 h3> Why doesn't Black take advantage of White's neglecting to meet ...d6 with h3 as he is 'supposed to'? Can't Black inconvenience White with ...Bg4 as he does in the 9.d4 variations?
May-24-11  MaxxLange: <Capcom> As I understand it, there's just not much point to ...Bg4 if White hasn't played d4 yet, and 8...0-0 is a more useful move for Black.

1 e4 e5 2 Nf3 Nc6 3 Bb5 a6 4 Ba4 Nf6 5 O-O Be7 6 Re1 b5 7 Bb3 d6 8 c3 Bg4 9 d3 is fine for White, for example. Moves like Nbd2, h3, and Nf1 with the idea Ng3 are going to force Black to retreat or trade off the Bg4 in a few moves, after which White can prepare d4

May-25-11  Capcom: <MaxxLange> I suppose your right. The extra tempo for Black (from d2-d3-d4) is less important than the two bishops in the closed position. Thanks.
