Ne odds challenge: queen vs rook

[pepechuy]

Hi.

Now, the second game against Berserk, taking the h8 rook.
A win for me.

¡This is my first win against Berserk in this challenge! (I lost the previous three games, two taking the a8 rook and one taking the h8 rook).
The critical choice is after 18. Ra1. Objectively, 18... Qb7 should be better; but I went for 18... Qa1. I end up with a knight for a pawn. I lost material, but the resulting position is much simpler, and the chances of me making a mistake decrease significantly.
After that, I had to play carefully, but it was not really difficult.

Hi.

A recap of the second round of this challenge.
The games played were (the results appear from my perspective):

Berserk, a8 rook: loss.
Komodo, h8 rook: win.
Berserk, h8 rook: win.

In the first two rounds 13 games have been played, and I have dropped 3.5 points.

Against each engine I have dropped:
Berserk: 3.0 (4 games)
Komodo: 0.5 (3 games)
Lc0: 0.0 (2 games)
Rodent: 0.0 (2 games)
Stockfish: 0.0 (2 games)

Taking each rook, I have dropped:
a8 rook: 2.0 (6 games)
h8 rook: 1.5 (7 games)

There will be only one game in the third round.
It is against Berserk, taking the a8 rook.

Greetings.

Hi.

Now, the third game against Berserk, taking the a8 rook.
A win for me.

¡This is the last game of the challenge!
I went for an open game with 6... c5. It can be more complicated, but I managed my position quite well, and won a pawn.
With 24... Bb6 I separated White's rooks, after that I was sure that I would force an exchange of rooks; which I did with 27... Rc1.
BanksiaGUI says that Berserk lost on time. I do not like it, and I do not understand how an engine can lose on time (it has happened a few times with Berserk within BanksiaGUI).
This time, I decided to take the win, since the final position is very easy to convert: White has no way to stop my passed pawn on a3.
