First adding to my comment to Monte Carlo:
when looking deeper, apparently the latest Black move
(...Bxf3) after all wasn't so bad because after 15...Rb8,
Black gets an open line for his rook, and thus enough compensation
(in fact we get some pawn grabbing but then indeed difficulty
for White to get into a winning endgame).
The purpose of this testgame for me was to get an idea about the
sort of intrinsic advantage for White (bearing in mind the idea
to diminish draws in correspondence chess with comp assistance).
Now in this game, i will get a better pawn structure, that's for sure,
the c7 pawn probably becomes isolated; but then in comp vs comp
play, this probably won't be enough for a win. So be it...
So, although i will continue the game for quite some moves (endgames
sometimes aren't so dull as they are supposed to be), one
little comment (mainly to mrbb), it's not about me having
failed to 'steer' the game into desirable anti-comp positions,
because like i suggested (with the nnue nets), this is almost
impossible. My simple strategy was to play good moves (in fact i tried to play the best positional moves possible, helped by the comps ofcourse).
NB also with 1.e4 i wouldn't have been able to increase the initial
advantage into significant further advantage (in the Berlin with Re1 as in LK's book after a while he suggest d5 to increase space advantage, but then this also won't be enough to win the game with perfect play, nor against a fast comp with the Nnue stuff and the alfa/beta combined).
But then after all this isn't surprising to me because chess after all
is a draw with perfect play. concluding, for correspondence chess,
depth/ computer speed indeed is useful, but after a while
we reach a draw limit and you won't have much chances
into pushing your opponent into a worse position (which in my
situation i try (or tried) to do with positional considerations,
having several engines at my disposal with different evals
(but then also being less efficient in the alfa/beta ergo depth
area). If someone else would like to try it (winning with White
under the same conditions, be my guest (*), good luck

Anyway, after a few moves, i might offer a draw, without
being ashamed because i simply was some sort of Idea operator
with some chess knowledge sure, but not claiming i could win
a game which basically is fundamentally a draw anyway.
PS and mrbbgian tell me where i could have played better moves,
and then try it against your engine, it's probably (almost?) impossible.
PS2 as for going into a 'anti-computer' strategy (and playing strange
opening moves), in general this is just the way i won quite some
correspondence games, against people who thought they could
play any known (yet rather obscure) opening, after which i was
often able to refute it, even before the Nnue age, and yes,
even with my apparently rather 'slow' computer (not that it matters,
the current game has shown that a faster comp will be able
to find a draw a bit faster, that's all. As for winning chances for
Black now in current positions, this ofcourse also would be balderdash.
