Kibitzer's Corner
Mar-30-03   Bionic Brain: Stein plays rather a dubious line in the King's Indian. He then starts a do-or -die sacrificial attack. Krogius, however, could have refuted the attack in several places, but I will only give the most important one here:

After 27...exf4, Krogius finds an excellent defence in 28.Rd1. This only fails because of Stein's more ingenious reply - 28...g5! This was the last minute that White could have refuted the attack.

28.Na4!! Bd4 <28...Bd6 29. Bc3> 29. Bc3 and now:

1)29...g5 30.Bxd4 Qxd4 31.Qd1 Qxd1 32.Raxd1 gxf3+ 33.Bxf3 (Kxf3 becomes dangerous for White)33...g4 34.Bxg4 Bxg4 35.Rdg1 and White emerges a pawn up with a good position;

2) 29...Bxd5 30.exd5 Ng5 31.Qd2 Re7 32.Qxd4!
(Bxd4 will become at least equal) 32...Rxe2+ 33.Kf1 Qxd4 34. Bxd4 gxf3 35.Re1 and Black does not have enough compensation for his piece (35...Rxa2? 36.Re7).

Mar-30-03   Alvis81: <<BionicBrain^^ no, you are not "expert" on the king's indian. Sad player is the word, when I see our comments about this brilliant game.
Mar-30-03   Alvis81: In that time it was not dubious, because only later it was discovered that Black´s best move was the elastic ...a5!.
Mar-30-03   ughaibu: Alvis81: I'm not sure exactly how to understand your expression of appreciation for BionicBrain's bringing of this game to the head?

31. Nxe2 ?

  LIFE Master AJ: I wrote GM Ray Keene ... and asked him which game was Stein's best. (Since I knew he had written a book on this player: "LEONID STEIN, Master Of Attack." I have an old, second-hand, raggedy copy of the original; and the 1988 reprint version.)

He was kind enough to respond:
< krogius v stein ukraine 1960-steins immortal, without a shadow of a doubt

rk>

While I have several other games of this player - which I like as much as this one - I will have to take Keene's word on this one. It IS a game of truly brilliant, stunning originality.

One final note, I searched the ChessBase database ... several times ... for this game. As of December 23rd, this game was NOT in there!

Dec-27-05   clocked: 28.Na4 Bd4 29.Bc3 Bxd5 30.exd5 and now not Ng5 but Re7

31.Bxd4 Qxd4 32.Qd1 Qe3 33.Bc4 Re4 34.Nb2 Rd4 35.Bd3 gxf3 36.Qxf3 Qd2+ 37.Qf2 f3+ 38.Kg1 Qg5+ 39.Kf1 Qg2+ =

31.Qd2 Bxc3 32.Nxc3 Re3 33.Rac1 (33.d6) gxf3+ 34.Bxf3 Qe5

35.Bd1 f3+ 36.Kf1 f2 37.Be2 Rg3

35.Rhf1 Rf6 36.Nd1 (36.Qf2 Ng5 37.Qh4 Rf5 38.Bg4 f3+) Qg5+ 37.Kh1 Rxf3 38.Rxf3 Qh5+ 39.Kg2 Ng5 40.Qd3 Rf5

Dec-28-05   sucaba: <AJ>, yes, a very good game. The black Kwing Ps outweigh the white N. Of course White could play 18. exd5. I understand from <Bionic Brain's> and <clocked's> analysis, that 28. Rd1 was the actual mistake while 28. Na4 would hold the draw.

43. _ Kh8! would be a #4, while 43. _ Re2 seems to be a #9.

Dec-28-05   syracrophy: There's no way to avoid the crushing 44...Re1+

  LIFE Master AJ: That's a joke, right?

White had at least four different moves on his 28th turn, (a4, Qd1, Na4, and Rd1) that probably won the game for him. Certainly Rd1 was NOT the losing move!!!

I suggest that you see Keene's book for more details. I have also been considering analyzing this game for my website, it is one of Stein's best and is also UNBELIEVABLY COMPLICATED!!!!!

Dec-31-05   clocked: <White had at least four different moves on his 28th turn, (a4, Qd1, Na4, and Rd1) that probably won the game for him.>

It IS complicated. Where is the white win after 28.a4 g5 or 28.Qd1 g5 For example:

28.a4 g5 29.e5 Qxe5 30.Bd1 (30.fxg4 Qxe2+; 30.Rh6 Bxd5 31.Nxd5 Qxd5 32.Rg6+ Rg7 33.Rxg7+ Kxg7 34.Bc3+ Nf6) ...Qd4 31.Nc7 Bc4 32.Ne4 gxf3+ 33.Bxf3 g4 34.Bc3 gxf3+ 35.Kh2 Ng5 36.Qh4 (36.Bxd4 Rh7+ , 36.Nxg5 Qd3 ) ...Qxc3 37.Nxc3 Rh7

28.Qd1 g5 29.fxg4 f3+ 30.Bxf3 Bxg4 (or Rxf3) 31.Bxg4 =

28.Qd1 g5 29.Rf1 gxf3+ (Qh6) 30.Rxf3 Bg4 31.Rd3 f3+ 32.Bxf3 Bxf3+ 33.Rxf3 Rxf3 34.Qxf3 Rxf3 35.Kxf3 g4+

Jan-03-07   Robert James: I also like the beauty of this game.

17...d5 is great.

Apr-06-07   M.D. Wilson: Stein was great.
Nov-29-08   Xeroxx: He was.

  computer chess guy: Rybka prefers 33. Be1 Bxg4 34. Bg3: I'm not sure this holds for White, but it looks like a reasonable try.
