I suspect it is dependent on the human.
I think that I am better than 1750 of your country(I have israeli rating 1997)
and I do not see a big problem with c4(but I also do not play this opening).
Of course Nxd4 is a tactical mistake and I do not see more than a draw for black
after a move like Kg7
I agree that delfi does not play like humans if it play that blunder.
Humans do tactical mistakes but different mistakes and even 1600 players do not
miss an obvious threat like Qxh6 and Nf6# even in 600+5 time control.

I do not see that 12...Qb6 as a big mistake but I agree that I expect humans to
be afraid to play it.
Movei prefers Qc7

I guess that it is dependent on your level.
tactics is important in chess and I guess that most players at the level of 1750
can get at least 200 elo better by only avoiding tactical mistakes that chess
programs can avoid in less than a second.
I believe that big part of the improvement that I made from 1600 to 2000 is
by learning to pay attention to the next move of myself or the next move of the
opponent.
I found at the time that I was near 1600 that often tactical or positional
mistakes that I did were because of not paying attention to the next move of
myself or of my opponent and one mistake may be enough to change the result of
the game.
I do not think that opening theory is very important and I guess that a strong
player may beat 2000 players most of the time even with 1.e4 a5
It may be interesting to do a tournament with prizes of 2600 players against
2300 players when the 2600 players start with something strange like 1.e4 a5
or something similiar and to prevent special preperation against specific bad
lines the 2600 players should not know the opening that they are going to play
and they may also get something bad after 2 moves when the first move make sense
like 1.e4 c5 2.Nf3 a5
The organizers may choose random bad line(of course they cannot know that the
opponent is going to play 1.e4 c5 2.Nf3 but they can have a bad line
also against 1.e4 c5 2.Nc3 and other options.
Maybe I am wrong but I believe that there are going to be 2600 players who score
more than 50% even when they have to play with black with random move that does
not lose material in the first or second move and not with theoretical lines.
