  Chessical: A possibility for Krasenkow may have been <27...Qc6> threatening a R sac on c3:

<28.Rhd1> Re3 29.d7 Rd8 30.Rd6 Qc4 (30...Qc5? 31.Bd4 wins) 31.Ba5 Rxe2 32.Bxd8 Rxb2 33.Kxb2 Qb3+ 34.Kc1 Qc3+, with a perpetual check.

Nov-09-04  Cyphelium: <Chessical> Perhaps white could try 27.- Qc6 28. Rdd1!?, with the idea 28.- Re3 29. Nd4. Play could continue 29.- Qc4 30. e6 Rxc3 31. e7 Rxa3+ 32. bxa3 Qc3+ 33. Kb1 and white wins....though I guess there are possible improvements for black on almost any move. =)
Nov-09-04  sandy simpson: Very entertaining, for everyone except Krasenkow.
Mar-15-05  chenturini: Very good game. If SPIELMAN lives again he includes THIS in the new version or "THE SACRIFICE ART"
Mar-15-05  your brilliance: <Cyphelium>: Thank you for the answer to <mkdir>. That black doesn't take the e pawn on moves 23 and 24, is the key to white's plan. It is doubtful that black could take the pawn and then defend by giving up the exchange on g7. Sasikaran must have seen all this around move 19 or 20. Brilliant!
Jun-02-07  argishti: WOWWW!
Oct-02-10  SharpAttack: Brilliant Game!!! I see creativity of Ivanchuk, foresight and accuracy of Anand and pure attacking art of Kasparov or Alekhine!

Apparently, white had everything calculated and mapped out...

Jul-04-15  FairyPromotion: This game deserves more recognition.

  plang: The Informant labels this game as a Dutch (A85). In a game played in the 1999 Moscow Championship White had played 12 0-0-0; 12 a3 was new. Krasenkov was critical of 19..Be8? suggesting the alternative 19..exd 20 Nxd4..Qxe4 21 fxe..Be5 22 Nf5..Bxc3 23 bxc with some initiative for White. 24..Qxe4 25 Ng3..Qf3 26 Nf5..Rxf5 27 gxf..Nd5 28 Bxd5..cxd 29 Rhg1 would have been winning for White. 29..Rxc3 30 Nxc3..Qxe6 31 d7..Rd8 32 Rhe1..Qf7 33 Re8+..Rxe8 34 d8(Q) would also have been decisive.

Voted the 4th best game in Informant 92 and surely a candidate for a Game of the Day.

  perfidious: This is similar to such gems as 1.e4 c6 2.d4 d5 3.Nc3 g6 or the other move orders: which ECO code applies? There are several which are not entirely clear.
Apr-16-25  King.Arthur.Brazil: The king guess that W have not much chose, must to be straight forward: 29. d7 Rd8 30. Ba5 Rff8 31. Bxd8 Rxd8 32. Rhf1 Qxe2 33. Rf8+ Rxf8 34. d8=Q Rg8 35. Qd6... other possibility is: 32. Rhe1 Qe6 33. Nf4 Qe7 34. e6 where W attack seems very powerful, I don't know if it is enough to win quickly.
Apr-16-25  Walter Glattke: 29.e6 Qxe2 30.d8Q+ Rf8 31.Qc7 Rg8 32.Rhe1 Qf3 33.Rd7 Qf8 34.Rf7 Qc8 35.Bxg7+ Rxg7 Rxg7 wins a rook 31.Qxa8? Rxa8 32.Rhe1 Qb6 33.e6 h6 34.Rd7 Rg8 35.Red1 b6 36.Bb4 Re8 37.e7 Kh7 38.Rd8 Kg6 -++
Apr-16-25  Walter Glattke: Corr: 29.d7 Qxe2 30.d8Q+ Rf8 31.Qc7 Qf3 32.e6 Rg8 33.Rhf1 Qc6 34.Rf7 ++-

  takebackok: Had to think somebody (me) missed something Wednesday, 29. e6 (if Qxe6 30. Nd4 Qxd6 31. Nxf3 has to be wining do to back rank and g7 weakness) so 29...Re3 30. d7 Rd8 31. Nd4 (threat Rhe1) Rxe6 32. Nxe6 Qxe6 33. Rhe1 Qf7 34. Rf1 Qe6 35. Rf8+ Rxf8 36. d8=Q Rxd8 37. Rxd8+ etc.
Apr-16-25  mel gibson: I was too lazy to work it out and only guessed the right move.

Stockfish 17 says:

29. e6

(29. e6 (1.e6 Qxe2 2.d7 Qxe6 3.d8Q+ Rxd8 4.Rxd8+ Qg8 5.Rxg8+ Kxg8 6.Kb1 Kf7 7.Kc2 b5 8.Kd2 h5 9.gxh5 Rf5 10.h6 gxh6 11.Re1 Rd5+ 12.Kc2 Rh5 13.Re3 Kg6 14.Kd3 Rh4 ) +6.05/43 489)

score for White +6.05 depth 43.

  An Englishman: Good Evening: The sort of game that will make you think that 2B + P > Q. Playing over the entire game, 19...Be8 looked like such a clever defense, but White must have seen both that and his reply long before.
Apr-16-25  mel gibson: Two connected passed pawns are very powerful.

Apr-16-25  vajeer: 29. d7 leads to a draw, but the defense is not easy to spot. 29. d7 Rd8 30. Ba5 b6 31. Bxb6 Rb3 32. Bxd8 Qxe2 33. Rb1 Qxe5

Black now threatens Rxa3# forcing 34.Be7 Qxe7 35. Rbd1 Rxa3+ 36. bxa3 Qxa3+ 37. Kb1 Qb3+ 38. Ka1 Qa3+

Apr-16-25  TheaN: Ugh this was quite the ordeal to analyze through and honestly I still messed it up. This ain't Medium/Easy CG, way too many options for both colors and White's way to victory is super precise.

You kind of solve these by patterns, rather than straight up moves. White wants one of his pawns on the seventh threatening promotion, allowing bishop and rook to support; Black on the other hand looks at a blockade either by Rd8, Re8 or Rd3, or perpetual after RxB. Meanwhile White has options to push pawns now due to knight forks.

I fell for the perpetual after <29.e6! Qxe2> 29....Qxe6 30.Nxd4 +- still gives White work to do, but it's going to be either ♖♗♘:♕ or ♖♗♙:♕ with the pawn on d6 fully supported. <30.e7?!<>>:

This seemed like the better path forward, given 'the threat is more dangerous than the execution' in Rhe1. However, Black has <30....Rxc3! 31.bxc3 (Rhe1? Rd3! -+) Qe5 32.Rhe1 Qxc3+ =<>>. The text makes sense in hindsight; White threatens d8 immediately and after 30....Rd3 31.Rde1!, a move of which the potential I did see (this works also if 30.e7?! Rd3? 31.Rde1 +-) but here it works because Black has no time for Rxc3. Very deceptive position.
