Define "equal".  Here I am considering the important detail that white is a
computer, black is a human.  In that regard, black is _not_ equal up to move 23.
 In fact, I don't believe black is anywhere near equal.  He isn't lost, but he
is far from equal and is at best fighting for a draw.  But in an open position.
And he just has no chance in that kind of position.

But I would take white anywhere along the way in that game, as a human playing
another human.  And by the way, any move after the "knight to the rim" move
finds white better IMHO.

Doesn't quite hold everything nicely together.  The comps were at about +1 here
already, went to +1.5 on the Rc7 move.  But then the next few moves were mostly
bad by black, turning this into a debacle.  But if there were not so many open
files, open diagonals, etc, black wouldn't have had to be worrying about tactics
all over the board.

But white looks better to me there.  Maybe not "winning better" but
"significantly better".
