*snip* (I am giving example): during Morphy years, king's gambit was so popular and almost every grandmaster used it regularly, now it is known that it is weak opening and grandmasters do not use it, *snip*
fyi, ivanchuk recently beat giri, karjakin & ding liren with king's gambit.
in 1 particular game, u will use 1 opening and 1 variation. if the position can be steered into territory equally familiar to both, then all the extra "knowledge" may not be useful.

hmm, may be the example I gave may be not true. but, let us focus on the topic, what is the knowledge Fischer did notknow but it is known now?
The English Attack vs. the Sicilian Najdorf was made popular by Nigel Short after Fischer's hey day. The Marshall Attack in the Ruy Lopez also developed a more fearsome reputation, so everyone started playing anti-Marshall systems with a4 or h3 instead of c3. The Berlin variation in the Ruy Lopez rose with Kramnik's victory over Kasparov in 2000. The Petroff used to be viewed as a drawing line. The Modern Benoni without an early Nf3 had some tough days after Kasparov beat Nunn in the Taimanov line. The Bayonet Attack vs. the King's Indian also probably came to prominence more recently.
One should probably note that Kasparov stopped playing the King's Indian near the end of his career because he said it was too much work keeping up with the theory of both the KID and the Najdorf. Even before he gave it up completely, he was already ducking the main lines.
I think we all have heard this "after Fischer chess theory has expanded/developed and Fischer did not know it, so he would have lost to many grandmasters of today" or something like that.
The reason why I ask is is not to argue but to understand: what opening was not in existence or was not known pre72 and was known/discovered after 72 and thus Fischer did not know that? or what theory he did not know?
can you enlighten me on this, give examples like this (I am giving example): during Morphy years, king's gambit was so popular and almost every grandmaster used it regularly, now it is known that it is weak opening and grandmasters do not use it, Morphy did not know it but modern grandmasters know how to fight King's Gambit, thus Morphy would have lost to modern grandmasters.
or just like King's Gambit, Evans Gambit was also a widely used opening by Morphy, modern grandmasters and even non-master strong players can easily win a match against Evans Gambit. these were openings theories Morphy did not know. so, the question is:
name me openings, chess knowledge, theory Fischer did not know but Kamsky, Anand, Kasparov, Carlsen, Karjakin, Polgar and e.t.c knew/knows?
one thing comes to my mind is endgame solution which was solved in 2000s, but that is hugely irrelevant since using a computer with 7 men endgame tablebase is not allowed on matches.
I do not know whether this quote is authentic or not, if authentic: what is that Bobby did not know but modern grandmasters knows let alone modern (as of 2016) 13 year old chess enthusiasts?
