GM Anand decides not to take Blacks Rook and lose his own Knight.
Instead he decides to save his own Knight and capture blacks knight instead
of Rook. It takes chess tiger 14.0, 8 hours to decide 28.Qxd1 is better.
What does your program say? Is there another program that will capture
the Knight instead of Rook as the 2755 GM did?
