Classical King's Indian Defense with ...Na6
FM Steve Stoyko discussed some of his games with GMs in this line, mainly to illustrate White's strategic ideas -- though I think there are ideas here for Black as well. He suggested I also look at some of Reshevsky's games to get a better feel for White's ideas, so I include one below.
Steve Stoyko (2340) - Leonid Sokolin (2630) [E94]
NY Action/New York, NY (3) 1998
So as to meet White's Pd5 push with ...c5 (or, more rarely, ...cxd5!?) without allowing dxc6 en passant. It also clears a path for the Queen and makes a potential secondary square for the Knight at c7 in case the c5 square does not work out. There are a few alternatives, the first of which is most commonly seen:
( White seems to have the edge after the most common alternatives: (a) 10... Nh5 11. h3 Gallagher) or (b) 10... Nb4 has been the approved move, threatening ... Bxf3 to wreck White's Kingside, but Joe Gallagher says White's best is 11. a3! Bxf3 12. gxf3 Na6 13. b4 as in Nielsen-De la Riva, Bled 2002)
Steve said that he was inspired by the way that Sammy Reshevsky used to play these positions-first building up control of the queenside before directing attention to the kingside.
(19... e4 allows White to build up a kingside attack by Kh1 and g4 at his liesure.)
White now targets the e5 pawn.
attacking the guard
now pressuring e4
Now White must play very precisely to realize his advantage since Black's pieces are poised to create counterplay on the kingside. Steve's move...
...appears to be inaccurate. Two alternatives suggest themselves:
(a) 26. Bxe4 might yield an edge, but Black has play: 26... fxe4 27. Nd2 Qg5 28. g4 (28. Nxe4 Nxe4 29. Rxe4 Bxh3?! 30. g4!) 28... e3 29. Nf3 Qh6 30. Nxg7 Qxg7 31. Qe2 h5!<=> 32. Nh2 hxg4 33. hxg4 b6 unclear )
Now we get to see how painful "the King's Indian counter-attack" can be for White:
0-1 Stoyko-Ibragimov (2672), World Open (he did not give me the year)
-- and "Ildar" went on to win the tourney thanks in part to this 3rd Round victory.
Stopping ...Ng4 and ...Bg4 ideas.
Encouraging White to close the game or face strong counterplay against e4. He may also have the idea, as in the game, of playing for e-file pressure even after White closes things with d5 by forcing the exchange of his knight at f4 (after Nh5-f4).
to stop Bxc3
with the much better pawns
otherwise c5 and Bc4
Black has recovered the pawn, but now White's pawn is passed.
This loses the exchange.
33... bxa2 34. Rc7+ Kf6 35. Ra7 h5 36. Rxa2 Bc3 37. Kg2 Kg5 38. Ra3 Bd2 39. Rd3 Bf4 40. Rd5+ Kf6 41. Kf3 Bc7 42. Rc5 Be5 43. Ke4 Bh2 44. f4 Bg3 45. Rc6+ Kg7 46. f5 gxf5+ 47. Kxf5 Bf2 48. Rg6+ Kh7 49. Kg5 h4 50. Rf6 Bg3 51. Rf7+ Kg8 52. Kg6 Bh2
Steve agreed to a draw, unable to find the winning idea in time pressure. Fritz suggests 53. Rd7 53. Rf2 Bg3 54. Re2 Kf8 55. Re4 is the same 53... Kf8 54. Rd4 Bg3 55. Re4! zugzwang 55... Bh2 56. Rxh4+-
Samuel Herman Reshevsky - Svetozar Gligoric [E96]
New York m/New York (1) 1952
Stoyko says that Reshevsky's games against the KID make a good study for anyone interested in mastering the positional concepts for White. Though Black does not play ...Na6 in the following game, the ideas it contains are still useful for these positions.
6... c6 7.
This sacrifice seems overly complicated, especially since White has the simpler line 38. Qg4! Rxc4 39. Rxf7 Qxf7 40. Rxf7 Rxf7 41. Qxg6+ Likely both players were in time pressure. The line that Reshevsky chose probably also works for White, especially since Black is hard-pressed to find the best response.
>= 41. Qxg6+
