Commentary for white move 7:

YASSER SEIRAWAN: But actually, Lubosh you did it very well by explaining that white has an advantage in space and what we mean by that is white's pieces, especially the center pawns at d5 and e4 control more of black's side of the board. This puts black in a space squeeze. And so by exchanging pieces like we've just seen, black eases his cramp and makes it easier for him to play.
