i dont know the exact years but it he changed shortly after he started the european chess circuit. He played Bc4 against some lines still like the Najdorf and dragon but he started playing main line agains most everything else. And i know he still played it occasionally for all you fanatics out there who would undobtably take the time to explain that he played it on such and such a date. 

But its just somthing to think about not as important as the move it self

How come a discussion on the sicilian sozin got sidetracked to a pirc??? I dont see any subtle hint of a distant similarity betn the 2 systems?

Nice to read you've got your Chinbese attack (against the Pirc) all lined up. Where did you get your documentation on that ?

One of my favourite Fischer games with 6.Bc4 is this one: 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bc4 e6 7.Bb3 b5 8.o-o Be7 9.f4 Qc7 10.f5 b4! 11.fxe6 (11.Nce2 e5 12.Nf3 Bb7 =+ says Baljon) bxc3 12.exf7+ Kxf8 13.Bg5 Ng4! Fischer-Blackstone, Davis 1964. White was already lost.
Just a little warning.

Read Fischer's book. (Faber or Simon Schuster versions) Plenty of Bc4 games in there. Remember it was Fischer who popularised the this opening. So there are a lot of  new ideas  (at that time) involved.

Another book which I found helpful is the RHM surveys. Not sure if that series is still around now. If there are current versions try getting a copy on the Najdorf. I think theres another one on the Schevy. Chk it out.

The plan with Bc4 is good against the Najdorf and the classical sicilian, against the Dragon it can be used with transposition into a Yugoslav attack, or in a positional way with 0-0, h3, Bb3,... with a future Nd5...
Against the scheveningen, it's not bad, but less efficient compared to the najdorf or the classical sicilian because Black have more choice to developp, for example a fast Nc5... Sure it can transpose with Nc6 or a6, but Black should not.

Personnally I only play Bc4 against Nc6 and a6, it's my favourite choice. Golubev's book is really excellent, I like it very much, very good theory in it to play the Fischer Attack, Sozin and Velimirovic. That's a really good choice for an attackant player.

It might not scare the draongeers but it may very well transpose into a yugoslav. Not only that but i dont think it is not so good against the Scheveningen. I mean it could very well just transpose into a Fishcer attack in the Najdorf or a Sozin or Velimirivic attack. Both are very exciting to play and i dont think that one can just say they wont cause problems. 

Im am still currently playing OTB my 6.Bg5 which is always a bit sharper but only because i need to fine tune the Bc4 stuff. 

ANy good books or software on these lines? Or a DVD?

There are some comments on it found on the Open Sicilian For the Ameteur thread here. See if it helps.
