Fischer-Sozin Attack with World Champions
I have a database of 28 000 games that includes only the games of World Champions from Morphy to Carlsen. The very excellent freeware "Scid vs. PC" has a function "Opening Report" that gives a report from any given position, and I tested this with Bobby Fischer's favorite Sozin Attack position:
Here is the report. The opening table in the end is interesting (as said this a table only from the games by World Champions).

5. Theory Table
Comments:
Fischer played originally 7.0-0 in his junior years but improved with 7.Bb3 saying the move "useful tempo move that limits black's options".
7...Nc6 is a move used by Anand with a good success. Otherwise it does not seem to give b much compared to other replies. 8.f4 was Fischer's reply with a pefect record against lower rated opposition.
7...Be7 was used first (by a WC) by Tal. Replies 8.0-0 and 8.f4 were both tried first by Fischer, but both with limited success. 7...Be7 has excellent record for black against Fischer-Sozin in WC's games.
7...Ndb7 was used first by Kasparov and the move has a quite poor record for b. Fischers reply was 9.f5, Kasparov played 9.e5 against it and the latter having a little better record for w.
7...b5 was second Tal's reply by which he scored the famous victory against Fischer. Fischer's original reply was 8.f4 and that move still has a poor record for w and excellent for black. 8.0-0 was Fischer's improvement and this seems to be even a refutaion to 7..b5. All black's main replies have poor results total. 8...Bb7 was Petrosian's reply, the "main line" that Fischer recommended in "60 games" 8...Be7 was first used by Smyslov. The line after 10...0-0 and 11.Bh6 was tested by Boris Gelfand against Kasparov in Linares 93 with 11...Ne8 with poor results. Only move that has a positive score against 8.0-0 is Anand's 8...b4, used twice by Anand, where after 9.Na4 b does not take e-pawn ..Nxe4, but plays 9...Bd7 with pressure to the Q-side.
