If white E5, move 6, was bad, and as the game was a half point win for
black, does that mean Chang thought black had a losing position after
move 5?

In game 3, again if white E5 was a bad move, did the pros feel black was
behind at move 9? I'm sensing more doubt in the game 3 commentary,
though :-)

Does anyone have white 2 at F5 in their opening book (*), in preference
to F4? Or has a refutation to F5 been found now?


*: Other than me :-) But I didn't collect enough games of this opening
to feel confident with it.
