King's Indian Defense & Attack by Hikaru Nakamaru today !

Fireworks start around move 20 ! A few comments on the following site:

I'd say that in the pure tradition of former world champs Robert J. Fischer and Gary K. Kasparov, Nakamura has now created his own KI Brilliancy !!

White to play and win

Hints:
White should capitalize on having all his pieces developed.
At least two Black pieces are not well coordinated and should be targeted.

Quick attacking repertoire against the Pirc

A little introduction to the Austrian attack against the Pirc. Even though this blog is primarily focused on tactics, the following opening primer is geared at creating tactical and sharp positions from White's perspective.
It also gives supporting material to the tactical puzzle Nakamura-Smirin presented in an earlier post ( look for tag Nakamura to see previous Naka puzzles !)

1 e4 d6 2 d4 Nf6 3 Nc3 g6 4 f4 Bg7 5 Nf3



A) Black can simply castle here 5..0-0
6 e5 Nfd7 7 h4 !?
Start of the attack.



7..c5 8 h5 cd4 9 hg6 dc3 10 gf7+ Rf7 11 Bc4
This is the tabiya (key position) in this variation.


Here Black can play 11..Nf8 or 11..e6. Current theory suggests the latter is better.
The Nakamura-Smirin Foxwoods 2005 game featured 11..Nf8 with a spectacular win for White ( 22 moves !).

B)

5..c5 Black delays castle to react in the center

6 Bb5+



After 6..Bd7 7 Bd7+ Black can recapture in two different ways

B1)7.. Nbd7 8 d5 0-0 9 0-0 Ne8 10 Kh1

White has attacking prospects with f4-f5. See Le Quang-Gurevich 2008 for more.

B2)7.. Nfd7 8 d5 Na6 9 Qe2 0-0 10 0-0


White has a pleasant position. See Shirov-Hulak 1992 for more.



NOTE:
In Variation B ( 5..c5 6 Bb5+ Bd7 ), I chose 7 Bd7+ but the main theoretical move is 7 e5. Here's an important game for this continuation ( 18 f5 and 20 f6 are typical of this variation ):
