That is a good position I think José! here Q5T is too positive about Black's
chances after 19. ..Nxf2. I'm no endgame expert, maybe Black can still draw but
+1.41 for Black is too much for sure.

Because after 19. ..Nxf2 the first few moves are more or less forced you could
look at the situation after 22. Ra1xe1 where Q5T and Rebel Century to a lesser
extent still favor Black.

In this last line after 23. ..h6 or 23. ..f6 I don't see why White(Q5T) wouldn't
play its g5 knight to e4 instead of putting its other knight in a tight spot
with 24. Nf5-d6. So much for Q5T. Century 2.0 withdraws to e4 and gives Black
0.28 pawns advantage.

That may be too much but I still think that Black could have had chances to draw
the game? That is not to say that 19. ..Ng4-f6 wouldn't have been better than
19. ..Ng4xf2, in my opinion.
Going yet a little deeper into the game I wasn't too happy with Black exchanging
its only remaining light piece, the black-squared Bishop to a White Knight that
I couldn't see doing much damage yet in the near future, on move 25. 25.Bg6xf4
is a move that Rebel Century 2.0 would play and I'm personally not convinced
that it is good.
