Commentary for white move 20:

MAURICE ASHLEY: We should mention, before you continue, that another move has been played. Kasparov has avoided blocking the position with c5-c4 and has instead played the move Qc7, which does allow the potential opening of the position by a pawn capture on c5. And the subsequent passed pawn by white.

YASSER SEIRAWAN: Yes.
