How should one defend this position against Deep Blue?

A new move, but not one which will resurrect this variation. A few examples
should demonstrate the true horror of Black's situation.
The idea of Kasparov's move is to secure the d5-square for his knight against
the thrust c2-c4. However, it gives White the chance to open new lines on the
queenside and bring his a1-rook into play without loss of time. Moreover, it
fails to deal with the main problem of Black's position - his inability to move
his queen. The only square available to her is b4, but this not only leaves the
e6-pawn undefended, it also allows White to gain time by chasing the queen.

Kaparov had lost interest in the game. He knew match is lost.
