Oct-01-03   drukenknight: can I take the pawn w/ my R? I think we are on same page. I will check back later.
Oct-01-03   xu fei: <drukenknight> I'm not sure what you mean. In my previous line 43...Rxe5 is not possible.
Oct-01-03   drukenknight: yes okay, what if Just block w/ 42..Re7?
Oct-01-03   xu fei: <drukenknight> 42...Re7 43.Rxe7+ Kxe7 44.Bd2

  AdrianP: Was 34 ...f5 forced?... it looks like a very unpleasant move to have to play, giving Korchnoi two connected passed pawns?
Mar-03-04   731: Xu Fei are you Xu Jun's sister? hehe
May-05-04   jaime gallegos: what a game ! AMAZING !!!
Jun-18-04   Bobsterman3000: Unbelievable. And Victor is still playing great chess!
Oct-08-04   aw1988: Korchnoi makes Tal look like his student in today's opening of the day.
Mar-26-05   babakova: why those repeating moves around 38-40? well the answer is simple: timetrouble. Viktor Lvovich had a great advantage and just needed to make "small" moves as not to ruin his winning chances.
May-07-05   weepingwarrior: Viktor Krochnoi has always been one of my favorites to study. He's still so active today. One of the greatest players to never become world champion.
Jun-14-05   ArturoRivera: what if 34.-Qf6?
Jun-14-05   Anastasia: 34.Qf6 Re2+ 35.Rf2 Rxf2 36.Qxf2 f5. White is still winning of course, but maybe slower than after 34.Rf2.
Oct-17-05   Ryan Razo: Why 20...Qd8 instead of Bg7? Tal let his dark-colored bishop leave its place in the fianchetto ultimately leading to 32.Bh6
Dec-23-05   Averageguy: <Ryan Razo> 20...Bg7 21.d6. This is a brilliant game of Korchnoi's, his King march is one I'm sure Tal himself would have been proud of.
Mar-18-06   coolzadar: What's wrong with 4.de instead of 4.Nc3?

The problem is that after black replies 4...fe, white's centre is weakened, and black's strengthened. Black can then develop naturally with ...d5, ...Bd6 and ...0-0. By keeping a pawn on d5, white cramps black. For instance, he can't play ...Nc6, and nor can he advance with ...d5.
Mar-20-06   coolzadar: I would have thought that 4..fe creates hole in blacks king side? A pursuable target?

But it's the old maxim, that a weakness is only a weakness if it can be attacked. Here, white simply isn't developed enough to go straight for the black king while the hole remains. Black will castle too quickly to be in any trouble, and then his stronger centre should start to tell.

  notyetagm: Korchnoi vs Tal, 1962

White to play: 50 ?

I particularly like how Korchnoi played 50 Rc7xBd7!,

giving up the exchange to capture the critical Black light-squared d7-bishop in order to break the <LIGHT-SQUARED BLOCKADE> of his connected passed White d6- and e5-pawns.

Once again, what is important is not one comes -off- the board but what remains -on- the board. After the exchange sacrifice 50 Rc7xBd7!, the <LIGHT-SQUARED BLOCKADE> of the White connected passed pawns has been broken and their advance immediately forces Tal's resignation.

Final position after 53 e6-e7 1-0:

  notyetagm: Position after 19 e4-e5!:


click for larger view

Korchnoi's 19 e4-e5! is a tremendous tactical blow.

Black appears to have four units covering the e5-square (Black d6-pawn, d7-knight, e7-queen, f6-bishop) while the White e5-pawn is supported only by the White f4-pawn.

But because of the support of the White f4-pawn, the three Black pieces <DEFEND> the e5-square -only- -after- the Black d6-pawn. This is the tactical idea of <PRECEDENCE>: Black has four units covering the e5-square but the Black d6-pawn must go first because White controls this square with his White f4-pawn.

But the Black d6-pawn needs to be on the lookout for the <PAWN FORK> d5-d6, <FORKING> the Black c7-knight and e7-queen. <<<<So if the Black d6-pawn needs to <BLOCKADE> the White d5-pawn, and the three Black pieces <DEFEND> the e5-square -only- -after- the Black d6-pawn does, Black does not really <DEFEND> the e5-square, hence 19 e4-e5!.>>>>

Jan-08-09   maxi: The more I look at this game, the more I like Victor's moves. I had my doubts about 35.Qf6 (instead play 35.exf6), but, positionally speaking, Victor's move is more sound and leads to a simpler win. I also had doubts about 28.Rac1 (instead play 28.a5 or 28.Bc4), but taking the <a> Pawn is not really sound as Tal should keep pressure on the h1-a8 diagonal with Bishop and Queen. So 28.Rac1 is really a positional trap. A very professional job.

  whiteshark: Korchnoi was, for many years, Tal’s <bête noire>. He alone seemed to be totally immune to the amazing tricks of the magician from Riga. ...
