"Did Fischer Know About the Berlin Defense?"

I can't help but think Bobby Fischer knew the Berlin was an equalizer. He said to a friend of his (who was it, I forget) that there was a way to equalize against the Ruy.

Naturally Bobby didn't say what the equalizing line was, but in My 60 Memorable Games, when the Ruy first comes up, he gives a near-equalizing line starting with 3....Bc5, never mentioning 3....Nf6 (as he presumably might not if that were the way to equalize against his favorite weapon as White). This could be interpreted as a near miss or hint at the truth, as it were (this notion is speculative but is consistent with the Fischer ethos and writing style if you understand them).

Bobby often played 4.Bxc6 against 3...a6, which is what one would expect if he thought 3....a6 was a second-rate move (i.e. that he would play a "refutational" reply). More important than all of this (except for the first point in the first paragraph) is that Bobby's opening analysis was exhaustive and fully informed by the old ideas that most modern masters ignore. Since he said he knew a way to equalize against the Ruy, I figure he probably did, that he correctly assessed both the position after his beloved 3. Bb5 and the effectiveness of the Berlin Defense, and kept the latter information to himself.

Anyone?
