Dec-02-07  Bobsterman3000: 21. Ne1 is a very, very bad move...

Dec-02-07  CarlosO: Maybe preventing 21...Qg4
Dec-02-07  ounos: Maybe 21. Bxe5 was the move.

Position after 22 ... ♗a6-c4! 0-1:

click for larger view

22 ... ♗a6-c4! 0-1 is just a stupendous <ZWISCHENZUG>.

The point is to force the White b3-queen (which has few <FLIGHT SQUARES>) onto the c-file at c2 or c3 so that the upcoming 23 ... ♗c4x♖f1 will come with a <GAIN OF TIME>, the unmasking of the Black c8-rook's attack on the White c2/c3-queen.

The difference between this <ZWISCHENZUG> and just grabbing the White f1-rook immediately with 22 ... ♗a6x♖f1 ? 22 ... ♗a6x♖f1 wins an exchange but Ivanchuk plays on. 22 ... ♗a6-c4! followed by 23 ... ♗c4x♖f1 wins a whole rook(!) and forced Ivanchuk's instant resignation.

The point of the <ZWISCHENZUG> 22 ... ♗a6-c4! is to force a <GAIN OF TIME>, turning the win of the exchange into the much greater win of a whole rook.

22 ... ♗a6-c4! is one of the very best <ZWISCHENZUG> that I have seen all year, right up there with Kramnik's ♖c1-c6! against Anand. And note that both of these great <ZWISCHENZUG> had the same purpose: to force the enemy queen onto a square or line so that an upcoming move would <GAIN TIME>. So both of these great <ZWISCHENZUG>, Nisipeanu's 22 ... ♗a6-c4! and Kramnik's ♖c1-c6!, are really all about <GAINING TIME (TEMPO)> so that a move can be made <FOR FREE>.

Dec-16-07  notyetagm: <Whenver you want to move a piece, you should check whether you can gain a tempo with that piece.> -- Weteshchnik, "Understanding Chess Tactics", page 157

Nisipeanu's 22 ... ♗a6-c4! is one of the best examples of this principle that I have ever seen.

  patzer2: <notyetagm> Thanks for pointing out the "in-between-move" 22...Bc4!

I feel bad for Ivanchuk having played 21. Ne1??, which is a move he probably would avoid even in blitz.

I figure Ivanchuk was probably planning on resigning anyway after 22...Bxf1 . However, 22...Bc4! setting up a discovered attack by deflecting the Queen to the c-file to win the whole Rook and not just the exchange only adds insult to already decisive injury.

Dec-17-07  M.D. Wilson: No doubt Nisipeanu's a good player, but Ivanchuk has been frustrating to follow lately (I'm sure I'm not alone in this regard). He is so talented and still has much to achieve, but sometimes I think he takes the meaning of "going to Planet Ivanchuk" a little too seriously. I think 2008 will be good to him, though.

Yes, what a great move by Nisipeanu.

Instead of the obvious win of the exchange with 22 ... ♗a6x♖f1?!, Nisipeanu played the much stronger <ZWISCHENZUG> 22 ... ♗a6-c4! and wins a whole(!) rook after 23 .. ♗c4x♖f1.

Jul-17-08  The Ninth Pawn: From Game Collection: The Ninth Pawn's Chess Course :

In Ivanchuk vs Nisipeanu, 2007 , Black plays the more complicated but more beautiful 22. ... ♗a6-c4! setting up a DISCOVERED ATTACK after 23. ♕b3-c3(c2) ♗c4x♖f1 and now the queen is attacked and Black wins a whole rook!

  jmboutiere: Ivanchuk is a great player but in this game Nisipeanu outplayed him. Nisi imagined a more psychological problem if attacking the white king, than blocked the center, than won a rook.Congrat.
Dec-22-10  sevenseaman: Nisipeanu has every piece 'on the money'. Very satisfying chess!
Oct-02-11  freeman8201: And Ivanchuk play s the Bogo too!@
Aug-01-13  JustAnotherPatzer: ho ho ho very cute, straight to 'Miniatures', one to be savoured - and against a high flying Chucky too!
Jun-30-15  SpiritedReposte: This reminds me of an MMA/boxing match where the guy is wobbled first then boom! Knocked out cold.
