Phase Three of FWFRCC Underway

What's happened in the four weeks since I posted Phase Two of FWFRCC Underway (July 2019), where the long acronym stands for 'FIDE World Fischer Random Chess Championship'? After 'Phase Two', which brought titled players into the competition, Chess.com issued a report FIDE World Fischer Random Chess Championship Heats Up, which said,
The Fischer Random action speeds up even more as the first knockout bracket begins on Sunday, Aug. 11. The tournament is the first of six consecutive weekly knockouts with identical formats of 16 players each, including two invited top-grandmaster players per bracket.

The following chart shows the dates for the six weekly knockouts. The note 'TBD' against each date means the start time of each event was not known at the time the chart was completed.


Schedule (frchess.com)

The first knockout event was announced a few days later in Nepomniachtchi, Harikrishna Headline First [FWFRCC] Knockout Qualifier (chess.com):-

The first of six knockout qualifiers will be hosted on Chess.com this Sunday, Aug. 11, featuring some of the strongest players in the world including GM Ian Nepomniachtchi and GM Pentala Harikrishna who will headline a pack of sixteen players vying for their chance to qualify for the next phase, the live quarterfinals.

GMs Nepomniachtchi and Harikrishna are currently ranked world no.7 and no.22 for traditional chess. The result of that tournament was officialized in Nepomniachtchi Qualifies For [FWFRCC] (chess.com):-

Russian top GM Ian Nepomniachtchi outlasted 15 opponents to reach the quarterfinals of the 2019 [FWFRCC], defeating GMs Zhamsaran Tsydypov, Sam Sevian and Pentala Harikrishna and the untitled Yurii Marinskii, in a stacked field.

The report included live video commentary by GM Aman Hambleton. I'm not sure what 'stacked field' means, but it must be something good.

Random Resources

A new video from Chess.com's IM Daniel Rensch explains the basics:-

Chess.com has also released a short puzzle test:-

That's a great idea, but it could be split into at least two puzzle series: 1) Do you know the castling rules?, and 2) Tactical devices that never arise from the traditional start position. Both of those ideas are easily expanded. Also worth a look is:-

  • Chess960 Dice (indiegogo.com; 'Chess based on talent not memory!')

HarryO of Chess960 Jungle, points out:-

Harry says, 'You announce "The NO LOOK 1.e4!" with your hands raised in the air'. One of the comments points to another sequence in the video where GM Nakamura plays 'The NO LOOK 1.c4!':-

From the 1978 Karpov Gambit in the Open Variation of the Spanish Game to "I didn't even look at the board." Thank you, Bobby Fischer!

I can't tell if 'Thank you, Bobby Fischer!' is sincere or sarcastic.

Phase Two of FWFRCC Underway

Last month's post, Titled Players Join the FWFRCC, reported on the second phase of the biggest chess960 tournament ever held, where FWFRCC means 'FIDE World Fischer Random Chess Championship'. Although other variations of that awkward acronym are in use, that's the one I pulled from an early page announcing the event, and that's the one I'll continue to use.

The plans call for six days of play, two tournaments per day, 7 players qualifying per tournament. Half of the 12 tournaments have been held, with the results available at World Fischer Random Championship: Qualified Players. The page mentions, 'The last four [sic] FIDE World Fischer Random Titled Qualifier events will take place on August 4.' The full schedule is shown in the following image.


Schedule (frchess.com)

Some well known players have already qualified, like chess960 specialist GM Andrey Deviatkin in the third event, and former FIDE World Champion Ruslan Ponomariov in the fifth. Chess.com, the host for the online events, doesn't require players to use their real names as identifiers, making it often problematic to recognize specific players. It does, however, require titled players to prove their identity. By the time of this blog's next report on the event, the third phase 'Knockout Qualifiers' should have already started.

Titled Players Join the FWFRCC

Two months after I posted Roadmap for a World Championship (April 2019), the first phase -- "Open Qualifier" Phase : For Non-Titled Players -- has finished. The results are available at World Fischer Random Championship: Qualified Players (chess.com).

Eight days of qualifying events, with four events per day and five players qualifying from each event comes to a total of 160 players qualified for the next phase. That 'Qualified Players' page showed that many players finished high enough to qualify more than once, when their second qualifying spot went to someone a little further down the list. Did any players qualify more than twice?

I loaded the list of qualified players into a database and created the chart shown on the left. It shows that there were nine players who qualified at least three times.

My database counted only 157 names, instead of the 160 I expected. Maybe there was a glitch in my procedure, maybe there was another reason, but my overall numbers should be accurate enough.

One Chess.com player, KokeFischer of Chile, qualified nine times, while two others, from Brazil and the USA, qualified four times. Are players from the 'New World' more interested in chess960 than players from the rest of the world? Maybe, but I suspect it has more to do with the start times of the four events favoring certain time zones.

So what's next? The rules (see the 'Roadmap' post for links) call for a '"Play-in" Phase : For Eligible Players', aka 'Qualifying Stage 2'. Specifically,

  • The 160 qualifiers from the 'Non-Titled Open Qualifier' stage will join titled players at this stage.
  • Players will register for tournaments they are eligible to play.
  • Players will compete in a 10+2, 9-round Swiss tournament based on the set qualifying schedule, with the top 7 finishers from each winning eligibility to purchase entries into the Knockout Qualifier Phase.
  • The total number of qualifiers from this phase will be 84 players.

The Schedule page (frchess.com) tells us when this will take place. First, here's the phase that has already completed:-

  • 2019-04-28: Open qualifiers begin • Non-Titled Players. Occurs 32 times to qualify 160 Players. 10+2. Top-5 to Play-in Qualifier.

The next phase starts a week from now:-

  • 2019-06-30: Play-in qualifiers begin • Eligible Players. Occurs 12 times to qualify a total of 84 Players. 10+2. Top-7 to Knockout Qualifier.

As for the rest of the tournament, here's the schedule. This is, of course, subject to change:-

  • 2019-08-11: Knockout qualifiers begin • 84 players + 12 Invited Players. 15+2. Two game mini-match. Winner of each 16-Player Bracket to QF.
  • 2019-10-04: Quarterfinals stage 1 begins • 6 winners from the Knockout Qualifiers join Nakamura & Caruana.
  • 2019-10-06: Quarterfinals stage 2 begins • 2 losers bracket winners join the 4 QF Stage 1 winners in a series of different time controls.
  • 2019-10-27: Semifinals begins • 3 QF winners join Magnus Carlsen for a semifinal with a series of different time controls.
  • 2019-10-31: Finals begins • Championship and Third-place matches begin with a series of different time controls.

Some of that doesn't make much sense -- e.g. '2 losers bracket winners' -- but it should all become clearer as the individual events arrive. The finals start on Halloween. Best costume wins a special prize?

Playing the FWFRCC

For the second time in my life I played in a qualifying event for a World Championship. The first was an ICCF correspondence event, which I documented in a post on my main blog, WCCC29SF14 (July 2007). The second was a preliminary event in the 'FIDE World Fischer Random Chess Championship' (FWFRCC). So far I've posted twice on this chess960 blog about the tournament:-

Until a couple of weeks ago, I hadn't even thought about playing in the tournment. My online ('live!') playing days ended 15 years ago, except for a few hours of chess960 that I documented on this blog in How I Spent My Free Day (March 2011). Blitz has never been my strong point and there are always other things to do. So how did I end up playing in the FWFRCC?

While I was working on the previous FWFRCC posts, I came across the page 2019 Fischer Random Open Non-Titled Qualifier - Chess Club (chess.com), and tried to join. A few days later I received the message

I can't let you into the Fischer Random club as you are not registered. If you wish to play in the open qualifiers and receive a free diamond membership please pay to register at frchess.com.

I hadn't understood the purpose of the club, but fair enough -- I paid my five dollars at frchess.com and became a member of the club. I started poking around the club's page and noticed comments from other members saying things like 'This is my chance to participate in a historic event!' They were right. Here I am maintaining a blog about the subject and I hadn't even considering playing in the first large scale C960/FRC tournament ever held.

Nine rounds at 10 minutes per player per game comes to at least three hours per tournament. Given per-move increments and organizational lags, that's probably closer to four hours. Finding a block of four consecutive, uninterrupted hours for an online tournament is not easy for me, even though there were four start times every Sunday. Last Sunday my wife was gone for the entire day and I knew if I didn't play on that day, I might not get another chance.

How to prepare for the tournament? In the days when I played FIDE-rated OTB events, my pre-game preparation was to run through tactical exercises. For chess960, I added choosing the first move as White from a random start position. I would have liked to do the same exercise with Black -- after being given White's first move -- but I don't have a tool to do that.

I also wanted to play in a preparatory tournament, in order to become familiar with the time control and the Chess.com interface, but I couldn't find a suitable event on Chess.com. I settled on playing a few games against their computer: Play Chess960 (Fischer-Random Chess) vs the Computer (chess.com). In the first game I blundered a minor piece, in the second I blundered a Queen, and I knew if I didn't want to finish the FWFRCC with a 0-9 score, I would have to improve my concentration. I decided I would play in a neutral setting, away from my office and all of the associated distractions.

I went into the tournament with a 1600 rating assigned by Chess.com. In the first game I was paired as White against a 2200 player. Although I avoided blundering, I spent most of the game on the defensive and finally lost on time in an unclear endgame. In my second game I checkmated my opponent in nine moves and was freed from the stigma of a 0-9 result. After five games I had a score of +2-3=0. I had been playing for exactly two hours, which averaged out to 24 minutes per game. It was supper time, the dog was begging to be fed, I was also hungry, and since I hadn't planned for these circumstances, I reluctantly decided to withdraw from the tournament. My final result ('bemweeks') is shown in the following chart.


Fischer Random Championship Non-Titled Open Qualifier 25

I lost another game on time when I had a won position, so it's clear that my play was too slow. The time control doesn't allow for spending additional time on the first few moves, which are the most difficult in a game of chess960. If I want to improve my result, I'll need to practice. It's that simple.

The $5.00 I paid for entry entitled me to two tournaments. Tomorrow is the last Sunday of qualifying events, starting at 8 AM, 12 noon, 4 PM, and 8 PM, all U.S. Pacific time. Since I live in central Europe, that translates to 1700, 2100, 0100, and 0500, my local time. Given other commitments, the only realistic possibility for me to play is at 0500 Monday morning, but even that is not so realistic. Since I would again have to withdraw after only two hours, it looks like I'm out of luck.

Kudos to Chess.com for organizing a terrific series of events. I was worried about running into some aspect of their interface that would prove to be a blocking factor, but everything worked as I expected. The site has been a strong supporter of chess960 for ten years. Without that support we might not be anywhere near a FWFRCC. Thanks, Chess.com!

A Difficult SP Revisited

These days the posts on this blog are overwhelmingly news oriented, but once in a while I like to look at a real chess960 position. A few months ago, in A Stockfish Experiment (February 2019), I wrote,
At first glance, there doesn't seem to be a high correlation between the Sesse results and the CCRL results. The first position where there is agreement between the two sources is [SP868] QBBRKRNN. I once discussed this position in 'A Difficult SP for Black' (April 2013). By coincidence, I'm currently playing the position in a pair of correspondence games and hope to have more to say about it in the future.

The two games have finished, so the future is today. For easy reference, here's a link to the original post: A Difficult SP for Black. Already on the first move, White threatens a smothered mate on the third move. In that post I noted,

Black has two methods of meeting the difficult challenge posed by 1.Ng3.

Those two methods were:-
1...Nf6 2.Nf5 Rg8, and
1...g6.

Both of the latest games used different methods of defense, as shown in the diagrams below. The top diagram is my game as White. The game started with the first line above, but instead of 2...Rg8, Black played 2...Nh5, guarding the sensitive square g7. This looks like a natural move, so why didn't I consider it six years ago? I looked at my notes from that game and recalled that the move appeared only infrequently on the CCRL database, which is a record of engine-vs-engine games. Even today on the CCRL, after hundreds more games have been added for SP868, the move 2...Nh5 has not been tried very much. Why not? Either there is a tactical refutation or the engines have a built-in bias against moving a Knight to the a-or-h files. I couldn't find a tactical refutation.

The game continued 3.b3 f6 4.d4 c6 5.Nf3 d5 6.c4 Bxf5 7.Bxf5 g6 8.Bc2 Nf7, after which I castled 9.O-O. I had the initiative for most of the game, but it turned out to be insufficient. The game eventually ended in a draw after about 60 moves, with an unavoidable tablebase position on the horizon.

The bottom diagram is my game as Black. Here I was attracted by the idea of sacrificing a Pawn with 1...Ng6. The move had been played three times on CCRL with a score of +0-3=0, all wins by Stockfish as Black. A Pawn sacrifice is also the idea behind 1...g6, but is either sacrifice really playable? I spent a few hours analyzing the various continuations after 1...Ng6, and concluded that it was no worse than the alternatives. The game continued 2.Nh5 f6 (diagram) 3.c4 d5 4.f4 Nh6 5.f5 Nh4 6.Nxg7+ Kf7 7.Ne6 Ng4 8.Rf3 Bxe6 9.fxe6+ Kxe6. This might be the first game I have played where my King was on its third rank before the 10th move. Even more curiously, it turned out to be safe there. I eventually equalized and the game was drawn on the 55th move.

That makes two games, two draws, and two more ways to handle 'A Difficult SP for Black'. The two new methods are:-
1...Nf6 2.Nf5 Nh5, and
1...Ng6.

Good thing the SP is more complicated than it looks. Even one chess960 position lost from the first move would mean trouble for Fischer's greatest invention.

Youtube Resources for FWFRCC

A few weeks ago I posted Roadmap for a World Championship (April 2019), about the '2019 FIDE World Fischer Random Chess Championship' (WFRCC? or FWFRCC?). After that post appeared, Chess.com released a slick video.


World Fischer Random Chess Championship 2019 (1:35) • 'Published on May 9, 2019'

The description said,

For the first time ever, a world chess championship has a truly open qualification system! Are you a Fischer Random genius?

The description used a couple of Youtube tags that should be useful for locating more about the event or the underlying games. I added a third tag for completeness:-

As long as I'm covering Youtube resources, let's add a video showing the first FWFRCC qualifier: Chess960 Championship Open Qualifier (youtube.com; MaxTheChessKid; 'Streamed live on Apr 28, 2019'). Max isn't a 'Fischer Random genius' and even stumbles over the castling rules in his first streamed game, but the video provides a good record of the look-and-feel of the qualifying event.

***

Later: A few days after I posted the above, Chess.com provided a list of World Fischer Random Championship: Qualified Players.

[Here] is the full list of non-titled players who've qualified for the first-ever Fischer Random World Chess Championship.

The first 'qualifier event' had 163 players, although the numbers have been declining since then. So far, 16 events have taken place, with another 16 to be played. The rules say, 'The total number of qualifiers from this phase will be 160 players from 32 qualifiers.' If a player qualifies from two different events, the additional place goes to another person.
