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 ... c4xf1 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 ... a6xf1 ? 22 ... a6xf1 wins an exchange but Ivanchuk plays on. 22 ... a6-c4! followed by 23 ... c4xf1 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>.

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

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 ... a6xf1?!, Nisipeanu played the much stronger <ZWISCHENZUG> 22 ... a6-c4! and wins a whole(!) rook after 23 .. c4xf1.

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) c4xf1 and now the queen is attacked and Black wins a whole rook!

|Dec-22-10|| ||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!|
