Poisoning the Grunfeld with The London Part Two!

| 0

This is a continuance of Part one of the series Poisoning the Grunfeld with the London system. 

As you'll remember, Part one was discussing the variation after the nonchalant 5...0-0?! allowing white to initiate a dangerous initiative. Black was pulverized in two miniatures I quote in that blog. ...

Now I will assess pros and cons, themes, and provide several games for the plan in the Barry after the highly defensive and rather blunt 5...h5?! that many players will be enticed to play to avoid having to defend the powerful attack with h5.

Cons for white:

  • No quick mate with h5
  • The square g4 may be temporarily weak as a result of pushing h4, Black may think about Bg4.

Pros for white:

  • Due to the committal thrust h5 by black there is no longer the annoying Nh5 resource that kicks our bishop back.
  • Later we will see that black only prolongs the attack and h5 is actually a weakening move as white will play f3, g4 after black is castled.

Recurring themes:

1. Nf3-Ne5 is seen repetitively because the knight is ensconced in the center of the board and cannot be conveniently evicted. The knight is especially powerful now as f6 will never be played. (The move h5 irreparably enfeebles the g6 pawn) and now Nh5, as mentioned is no longer an option. 

2. f3-g4 with a crass pawn storm, such hooliganism is fully justifiable as black has made positional inaccuracy by pushing h5 and then being inevitably forced to castle on the kingside. 

3. f3-e4 this central strategy is also possible although it's less frequent. 

An overview of our set-up (All Londons/Barry Attacks rely on a fundamental formation) d4-Bf4-Nc3-e3-h4-Nf3-Qd2-  0-0-0   - Ne5-f3-Bd3- g4! is the plan and regularly Grandmasters win games against players only 100-200 points below them.

6...Bg4!? is covered in the first two games. While the riskier 6...0-0 is covered in game 3.

Here black opted for an early Bg4 followed by 0-0-0 to avoid white's attack however in the game Karjakin masterfully exploits black's dark square weaknesses and employs the theme f3, e4! later on.

In this effulgent king hunt, white executed both f3-g4 and f3-e4 . This game is an embodiment, a living testimony to the beauty and fighting spirit embedded in this line. This truly is an epitome to spectacular and thematic chess.

In this game white expedited the advance g4 by playing it right away without the preparation of f3. Also Nb5 was played to force black to place his knight to a less than desirable post on a6. Finally it transpired to be a technical labor on white's part as in a drawish double-rook ending, he eventually wore down his opponent.
