It isn't easy to comment as all went downhill very fast for FM Miguel A.
Ballicora in the first game of the match. Gaviota took the lead early and
smashed him.
Tactics ruled this sharp game.
Gaviota used its release book ( kudos to Carlos Pesce).
Miguel avoided the Benko mainlines. I disagree with him though that the Benko is
such a good opening for computers - but it certainly can be tough to play with
white at such a fast time control.
The game with some very brief patzer remarks with a little help of Fritz - take
them with a grain of salt:

An equal position after leaving the opening book with chances for both sides.

11. Nd2 Ne8 12. Nc4 f5

I think it should be 11..Ne8?! and 12..f5?! as comments here. This looks like a
very artificial plan chosen by Gaviota that only works with white's help.
11...e6 looks more natural to me.
}
13. Bd2

13. exf5 looks much better and seems to lead to a slight advantage for white.
}
fxe4 14. Nxb6

This looks like a bad trade. Both 14. Nxe4 and 14. Qb3 should have been enough
to maintain an equal position. Now black has the advantage.

The decisive mistake, played after only 18 seconds. White's position has become
critical and he is under big pressure. Here was the last chance to break the
chains with
20. g4!. For example 20...Bxe4 21. Qxe4 exd5 22. Bxd5+ Kh8 23. h3 Qxe4 24. Bxe4
Rxb2 25. Rxb2 Bxb2 26. Rb1 or
20...Bxg4 21. a3 Qb6 22. 22. dxe6 Bxe6 23. Bxe6+ Nxe6 24. b4. Sure black is
better in these variations but is it enough to win?
}
exd5 21. Rxd5 Nxd5 22. Bxd5+ Kh8 23. b3
{
23. a3 might have put up a little more resistance but after 23...Bxe4 24. Bxe4
Qb3 25. Qd2 Rb6 white looks quite dead, too.
Rest is silence.

30...c4 is easy but pretty.

A pleasant game by Gaviota but white really played in its virtual hands. Gaviota
played a few fun blitz games against Miguel after the match game was over and
they showed that with a slower build-up he will have better chances.
There were 10-12 spectators watching the match game which isn't that bad with
Gulko-Fritz scheduled at the same time :)
Next game will most probably be played next weekend. I am looking forward to
Miguel's battle for revenge.

Time usage of Gaviota looks not very refined yet - I bet I could guess the
formula ;)
