That's what I mean. It creates a very unbalanced position where a minimal
inaccuracy makes you pay. That is true as long as they understand thru the eval
the long term planning (i.e. domination in the q side).
Computer won't play well with white... it is easier for a human to play
the black side.

I do not think is bad. It is certainly double edged but I think it is ok for
black. Not to mention, it is very anti-human :-)

18. ... Qb4 is what escaped from my thoughts. Otherwise I could have had
a more solid position with one more tempo. For that reason, yes, Nxb6 is
not a good move. Rfd1 is not good but white is in deep trouble already.

At this point I thought I could resist for a while blockading the white squares
since black has not open lines for their rooks. But the sequence from now on
from gaviota is just perfect. Computers do not forgive in these situations.
>Rbe8 24. f3 Bd4 25. Qd3 Re5 26. a3
Qd3 is the only move, otherwise black trades the bishop with check and Qd4+
winning the bishop.

I tried to see if Gaviota executed well this, not allowing any perpetual
situation (that sometimes falls out the horizon for some computers).
