Freestyle report + annotated games

Post by Alkelele »

Hi all,

Here is my report on my participation in the 5th Freestyle final to be sent to CSS. I hope it will be interesting. Please feel free to comment on things you liked or that you think are missing, and ask any questions you may have.

(I will post the PGNs of the annotated games below this post)


First, a big thank to the organizers and sponsors of the tournament, and congrats to the prize winners.

The Flying Saucers team consisted of one human player + computer(s). I am 30 years old (2163 FIDE), from Denmark, and a mathematician by education. This was the third Freestyle event I participated in. I have played as a sole centaur each time. Currently, my main activity in chess is freestyle chess and opening studies with this in mind. I am also a member of a local chess club and enjoy the socializing that takes place around low-level club league matches.

My hardware in the preliminary was an AMD dual core Opteron, which has to be considered sub-average hardware these days. As it is, I know for certain that at least one other finalist qualified with even worse hardware than me, so to get that question out of the way, no, Freestyle chess is still not only a question of spending bucks on hardware. My three wins in the preliminary consisted of one "endgame-swindle", an attractive attacking game vs. GM Juri Solodownitschenko (who, despite this loss, managed to qualify for the final), and finally a successful defense against a wild Bxf7+ sacrifice in the 2.c3 Sicilian.

Before the final, Rybka programmer Vasik Rajlich had once again kindly offered me to let me use his best system, this time a quad-core Intel. My technical setup then was:

Fritz 9 interface, with two instances of Rybka running. The quad on internet-pipe running in 1-variation mode, and my own dual core running in 2/3/4-variation mode. This way, I would be alarmed by deep resources and assessments fast, while at the same time getting immediate information about the forcedness of the investigated positions, in other words, how many alternatives would also be worth a check.

I decided to exclusively use only one engine this time. The advantage of using several engines is that different engines may evaluate positions differently, and this (+search differences) results in one engine finding some potentially strong move faster than another engine, and vice-versa. However, and I think this is an important point, a key part in strong centaur analysis is to know both the strong and the weak points of your favorite engine. The engine output needs to be interpreted, and here experience with your engine is very important: What kind of lines does the engine tend to not pay enough attention to, and which types of positions does it tend to misevaluate. If you have a good feeling for this and have developed methods to adjust for this + integrate your own input, you should have a considerable advantage. Once this is achieved, I am not so sure the output of a second or third engine will improve the decision process much. At any rate, I didn't have the hardware to support a second engine, nor the (necessary) experience with working with two different engines at once.

Unlike last time, I used the endgame TBs installed on my system, which indeed turned out to be a probably better decision. The games themselves, I played through the free Playchess client.

After the preliminary play-off matches, I once again spent considerable time preparing for the individual opponents in the final based on the expected pairings. However, 4 days before the final, a random pairing was announced, and I had to scrap much of my preparation, and also had to settle on only getting 4 whites. Nevertheless, one thing was still clear: The final could very well become some kind of a Najdorf festival! A majority of finalists were 1.e4 players, and I think also a majority were black Najdorf players, at least potentially. This suited me quite well, as I had been intensely studying various topical lines for some months prior to the final.

As it turned out, I ended up in three Najdorfs as black, and one Najdorf-turning-into-odd-Rauzer as white, and those 4 games gave me the number of wins necessary to clinch first prize. I also had some pressure against runner-up team Cato the Younger after they had gambled with 1.h3 (intending a French in the forehand), while I was under quite serious pressure as black against Kaputtze in round 7 and as white in round 9 vs. Ciron, a very nervous affair on my side. My remaining two white games were fairly uneventful draws. Perhaps next time, I will insist on getting 9 blacks in the final!

Overall, I am of course very satisfied with my performance. I managed to hit the ball when I got the chance, and I held the draw in the couple of games where I got the worse of it.

I have annotated 5 games, 2 from the preliminary, and 3 from the final. I have mainly focused on situations where the "human touch" was crucial, trying to relay what went on behind the scene. Various decision methods and issues of pre-game preparation are touched upon. Finally, I hope that the reader will also simply find the games themselves interesting and fascinating!

an alarm bell. I began looking intensively for "hidden resources" and managed
to find the winning line starting with 28.Re8+. For the next few moves, I

Juri always plays this Nd7-Nde5 interpretation of this system instead of the
more common Nxd4. He blitzed out the opening moves for a few more moves, while
I was definitely out of any kind of preparation. I was not overly concerned by
this fact, though I certainly paid it due respect. I had had a similar
experience as white vs. IM Dennis Breder in the 4th preliminary in a Tarrasch
French, and in that game I was lucky to be able to win in perhaps one of my
best Freestyle performances so far. I decided to take a good deal of time to
ponder the various options here and see if I could get a position to my liking.
Perhaps an interesting observation is that big swings are quite uncommon in
games at this computer-assisted level. After the opening and early middle-game,
it is often play for two results only. Consequently, I feel it is usually
worth it to invest some time in this phase to try and make sure that it is the
two right results. Of course, the risk is that you still get a worse position
and a disadvantage on the clock as well, or that you do not put enough time
pressure on the opponent so as to make defense more difficult. [%emt 0:00:01]}

usually plays Qa5, but this is not possible when the king is already on b1.

{My opponent in this 1st round game of the final was a team led by Rodolfo
Gallo from Italy. In the preliminary and the play-offs, he had been playing as
a pure engine (backed by a very strong home-cooked book), but in the final he
played as captain of a centaur team. Before the game, I expected and hoped for
a continuation of an intense theoretical discussion having taken place during
the preliminary and the play-offs. While making these annotations, I chatted
briefly with Eros Riccio from the Rodo team, and comments about their

actually not any good.} Nc7 25. f6 Bd8 26. fxg7 Kxg7 $1 (26... Re8 {

A novelty according to my database. I had begun investigating this move
several months prior to the 5th Freestyle tournament, as a result of some
insight into the ultimative status of 24...Bd8. The main idea of the move is
to take the sting out of any f5-f6 push. Later on, black may play f7-f6
himself, trying to lock up the kingside and get an attack on the queenside.
The move was a surprise to my opponents. [%emt 0:00:13]} (24... Bd8 25. Rh3 {

The real schocker of the game. At first, my opponents wondered if I might have
made a mouse-slip! No engine on earth will find or like this move, but... I
went into the final wanting exactly to get this position on the board in the
first game. [%emt 0:01:17]} ({After} 26... Rxa3 27. bxa3 Qxa3 28. Rd2 Nc7 {

it is time to contemplate the consequences of 26...Rxb5. While black is down
an exchange, white has his share of problems too. The white queen is tied to
inactivity on the b1-square, and the white king is locked on c1, at least for
the time being. Additionally, the white rooks are not really a threatening
force by themselves, thus leaving pawn-pushes on the kingside a lot less
dangerous for black. After the conclusion of the game, I was a bit surprised
about how deadly the 26...Rxb5 idea had turned out to be, as I had been
spending a majority of the time during preparation trying to counter white's
most critical tries in the following positions. On the other hand, white comes
into this position unprepared. Once you begin analysing, you will see one line
after another go from +0.50 to 0.00, and sometimes below that. In other words,
white is stepping into a mine-field, and already it is tough for white to
figure out if he is playing for a win or a draw. My opponent spent 20 minutes
here and was thus down to about 25 minutes, while I still had the full hour
left. I will leave the analysis of the next few moves to the discretion of the
reader. [%emt 0:00:14]} 31. Nd4 {[%emt 0:19:49]} d5 {[%emt 0:00:30]} 32. Rh3 {

is lost after this, and I have tried to indicate below what I consider black's

You are welcome. :-)

You mean, like a logo for my "team"? That I don't have, but the name should provide some interesting options!
