Lessons of the King's Gambit 2

Dear ladies and gents,

    Mr. Neil McDonald asked in his book "The King's Gambit, A Modern View of a Swashbuckling Opening" :  "Why wasn't the strength of 3... d6 [Fischer's Defence] appreciated in the heyday of the King's Gambit by Anderssen, Morphy and others?"

    Well, Mr. Anderssen prefers tactical play, especially along the main diagonal of the chess board, so playing as Black, he wouldn't like to push the g-pawn and let White uses the main diagonal on him.

     And for Morphy, as for many American players also, likes to hit the pawns early on at the 7th-rank.  So, for Black's playing 3... d6, would create a potential weakness at c7!  Because it takes time for a rook to get to b7 and it takes forever for the Black bishop to guard the c7-pawn.

Love,
