| Dec-05-04 | | maxundmoritz: <Alkaff> Let me complete the winning line after 28 Ba3. 28.. Rb2 29 Bxb2 Nb4 (and ignoring the check on Qxf7) 30 Kb1 Qxa2+ 31 Kc1 Qxb2#. |
 |
| Dec-05-04 | | DanielBryant: I saw Rxb1 but I was trying to analyze the immediate ...c3. Didn't quite work. |
|
| Dec-05-04 | | fgh: Solved in 1.2 seconds. |

| | EXIDE: Good puzzle. Great play. I spent a lot of time bringing in the black bishop into play with 23...Nxe5 24.RxN,Rxb1+ etc. Could not close it out however. |
|
| Dec-05-04 | | Calculoso: Why does black play c3? |
|
| Dec-05-04 | | CHEG: 25 ... c3
blocks the white queen from coming back to defend white's king and allows white some protection on the b2 square. |

 | | kevin86: Ouch!- if 28 xc4  xc2#
Fancy finish! |
|
Dec-06-04
 | | patzer2: With the puzzle solution 23...Rxb1+!, Black exploits the weakened White Queenside castled position with three consecutive deflection moves to set up a decisive mating attack with 26...Nb4! (27. Qd3 Qc4!; 27. Kb1 Nxa2+ Kxa2 28. Qa3  ) and 27...Qc4! (28. Bxc4 Nxc2#). |

| | patzer2: <MyCatPlaysChess> <Was there a better defensive try for white on move 22 instead of 22. Nb1?> Good observation! You are correct that 22. Nb1?? was a blunder. Better was 22. Qe3! when White holds the position with a small but clear advantage. Play might continue 22. Qe3! Qa5 23. Qd2! Nc6 (23...Qb6 24. Ba3 Nc6 25. Rb1 Qd4 26. Qxd4 Nxd4 27. Rbc1  ) 24. Nxd5 Qxd2 25. Bxd2 exd5 26. Bc3 Rd8 27. Bg2 with a position favoring White (due to Black's weak pawn on d5). |
|
| Dec-07-04 | | beatgiant: <patzer2>:
<Play might continue 22. Qe3! Qa5 23. Qd2!>After this, Black can try to keep the attack alive with 23...d4!? so that if 24.  xd4 c6 25. d2 xe5 opens a powerful diagonal for the Black bishop, or if 24. e4 c3 25. xd4  b4 26. d6 ab8 27. a3 c6! brings the knight into the attack. This seems to favor Black, but it is complicated enough that maybe a computer should confirm this (<Crafty>?) |

| | patzer2: <beatgiant> Thanks for your analysis. I stand corrected. Looks like 22. Qe3? doesn't work for White afterall. After 22. Qe3? Qb4! White is busted. Play might continue 22. Qe3? Qb4! 23. f4 Nf5 24. Qd2 Rxa2+ 25. Kxa2 (25. Nxa2 Rb1#) 25...Ra8+ 26. Na4 Rxa4+ 27. Ba3 Rxa3#. < |
|
Dec-07-04
| | patzer2: <MyCatPlaysChess> According to Fritz 8, which is a strong computer program, it would appear White has nothing better than 22. Nb1. Unfortunately for White, Black wins in this line and in all other variations. After 22. Nb1, Fritz 8 gives 22...c3! 23. Nxc3 (not 23. Qxc3 Rxb1+  ) 23...Nc6 24. Nb5 Nxe5 25. Rxe5 Bxe5+ 26. Bb2 Qxc2 27. Rb1 Qa4 28. Qa3 Rxb5 with a clearly won position for Black. |

| | Cyphelium: <patzer2 & beatgiant> I was analysing the same 23.- d4!? move as beatgiant, but I didn't post anything because I couldn't quite make it work. True, after 22. Qe3 Qa5 23. Qd2 d4 24. Qxd4, 24.- Nf5 wins the piece back immediatly (25. Qxc4 Rc8; 25. Qd2 Rd8). I would certainly have been tempted by this line in a practical game - the endgame looks good for black- but the line given by beatgiant might be even stronger, since the pressure on c3 is very unpleasant. But 24. Ne4 is more of a problem. After 24.- c3 25. Qxd4 Rb4, 26. Qxc3!? might be playable, since 26.- Bxe5 runs into 27. Nf6+, for example 27.- Bxf6 28. Qxf6 Nd5 29. Rxd5 exd5 30. Bb2. Another variation: 26. - Nd5 27. Rxd5 exd5 28. Ba3 Bf8 29. Bxb4 Bxb4 30. Qc6. So it looks like white might hold? This is very complicated though, and maybe black has a win in there somewhere? <patzer2><After 22. Qe3? Qb4! White is busted> The variation you provide to support this claim doesn't make sense. It seems like you've analysed without the black pawn on a7. =) |
|
Dec-08-04
| | patzer2: <Cyphelium><It seems like you've analysed without the black pawn on a7. =)> Thanks Cyphelium you are correct (I set up the board to analyze without a key Black pawn on a7), and that changes the entire assessment. I'll do another analysis for 22. Qe3, and this time with the right setup (maybe removing your own pawns could be a new variant of Fischer Random, or in this case Patzer2 Random). |
|
Dec-08-04
| | patzer2: Looks like 22. Qe3! does hold the position with a small advantage (or at least equality) for white afterall. Sorry for the confusion on the second analysis look in which I left off one of Black's pawn on a7. An expanded analysis, using Fritz 8 to validate, follows: 22. e3! a5
[22...Qxe3 23. Rxe3 Nc6 24. f4 d4 25. Re4 dxc3 26. Rxc4 ] [22...Qb4 23. a3 Qa5 24. Qd2 Qb6 25. Qd4 Qxd4 26. Rxd4 Nc6 27. Rdd1 Nxe5 28. Ka2 Nf3 29. Re3 Nd4 30. Rd2 Nf5 31. Rh3  ] Note: this reverses my previous assessment that <after 22. Qe3? Qb4! White is busted>. In fact, 22. Qe3! Qb4!? seems to give White slightly better chances in a complex and unbalanced position. 22. e3! a5 23. d2 b6
[23...d4? 24. Ne4! Rb4 (24...c3 25. Qxd4 Nc6 26. Qc4 Nb4 27. Re2 Rd8 28. Nxc3 Bxe5 29. Rxd8+ Rxd8 30. Rxe5 Qxe5 31. Qxb4 ) 25. Bxc4 Bxe5 26. Nf6+ Bxf6 27. gxf6 Nf5 28. h5 Rab8 29. Bb3 ] Note: <beatgiant>, on second look it does appear that White wins after <22. Qe3! Qa5 23. Qd2 d4? 24. Ne4! >. Of course in the line that follows after 22. Qe3! Qa5 23. Qd2 Rb6! below, White equalizes with only a slight advantage. 22. e3! a5 23. d2 b6! 24. b2 ab8 25. xd5 xd5 [25...Qxd2?? 26. Nxe7+ ]
22. e3! a5 23. d2 b6 24. b2 ab8 25. xd5 xd5 26. xd5 xd5 27. d4 c6 28. b1 d8 29. c3 |

Dec-08-04
| | patzer2: <MycatPlaysChess> If a cat has nine lives, then hopefully 22. Qe3! has at least three (good, bad, good again) as it does appear to save the game for White. The availability of 22. Qe3! as a saving resource also validates your opinion that 22. Nb1?? was the losing blunder. |

| Dec-20-04 | | SnoopDogg: Not only am I impressed with the 19-move calculation, but the fact that this game proves that Petrosian looks at all lines including ones concerning sacrifices. Even calculated it down to the bone with 27. Qc4!. Scary, very scary to play Petrosian. If he were alive today, Deep Junior would have nightmares of him in sleep mode. |

| | mormonchess: <SnoopDogg> Hehe, you're right. It's a shame that Petrosian isn't around anymore. He died way too young (age 55). I echo all the comments here. Petrosian calculated very deeply. What is not commonly known was shared by Kasparov in his third volume of "My Great Predecessors": Petrosian was unequalled at blitz chess. In fact, when young Fischer visited Moscow, they finally sent Petrosian in to wrestle with the kid at blitz because Fischer was beating the others left and right at blitz. Petrosian was able to beat him, while the others struggled. He was a great chess titan! |
|
| Jun-16-05 | | SnoopDogg: I heard also that he let young Yaz win a few games because Yaz didn't want to play Petrosian in blitz because he knew what would happen. Then Petrosian won the rest of the games and crushed his confidence hehehe. |
|
| Nov-16-05 | | Richerby: <karnak64><Botvinnik once said: "If Tal offers a sacrifice, accept it. If I offer a sacrifice, consider it. If Petrosian offers a sacrifice, resign."> I think you have the quote slightly wrong. This is mentioned in volume II of Kasparov's book as (quoting from memory), ``If Tal offers a sacrifice, accept it; if I [Botvinnik] offer a sacrifice, analyze it and play it on its merits; if Smyslov offers a sacrifice, decline it.'' I'm sure it was Smyslov rather than Petrosian and reasonably sure the advice was to just decline the sacrifice rather than resign. |
