Dear chess community,

As many know the WYCC 2014 is held in Durban, South Africa and there are 3 countries from Oceania being represented: Australia, New Zealand and Palau. You can follow the progress of the tournament of the Aussie's, Kiwi's and Palauan's fromt he official website which is http://www.2014wycc.co.za/2014wycc/Home.html

Breaking news from the official website which states there is a ban on traveller's from Embola-affected countries due to prevention of yellow fever in South Africa.

I will also happen to fly from the European Club Cup in Bilbao directly to the WYCC to be an arbiter for the remainder of the rounds for the championship.

If you want to follow the results of the Australians on the one page, this is what you're looking for (http://chess-results.com/tnr144247.aspx?lan=1&art=25&fedb=AUS&fed=AUS&turdet=YES&flag=30&wi=984). At this stage the Australians as a whole are performing quite decently.

Zhilin Guo managed to beat someone from Russia!

If anyone's looking for a guide to how someone is performing relative to rating they should ignore the PRs published on the chess-results page as these are frequently deflated. Instead clicking on the player's name brings up their results which include a Rating +- figure that indicates if the player is so far gaining or losing ratings points. Most rated Aus players are gaining points so far and some are gaining large numbers of points - this is quite unusual in junior comps as our juniors tend to be less underrated than other nations' (perhaps ours play more rated comps or against more adults.)

24-09-2014, 05:06 PM
Yes, in particular, Zhi Lin is gaining 80 pts so far! :)
How does chess-results calculate performance ratings? I think they are way off probably because of how they treat unrated opponents.

That's part of the problem. They treat all unrated opponents as being at the rating floor (I think they give them 1200, or maybe it's 1000). That would still be not so bad if they calculated True Performance Ratings but instead they used batched calculations (by averageing the ratings of opponents), which disadvantage players who have had one opponent much weaker than the rest (as a lot of players do in the first round, or whenever they play an unrated opponent.)

Zhi Lin Guo just keeps on winning and winning!
Most of the Australian players are gaining rating points, a good sign.

I have Tom Maguire's TPR after round 8 at 2080 (rated 1810). Zhi Lin Guo (rated 1632) at 2063 even after losing in round 8.

May be it makes sense to send lower rated juniors to world youth - they do come back with rating points and relatively (if not very successful) performances

I don't know about the others, but I know I would be slightly less disgusted if I hadn't blown three easily drawn endings to higher rated players :P Unfortunately you can't win them all, my round 10 opponent decided to agree to a draw in a won position, and the whole experience was wonderful, so I'm not complaining!

What does everyone think of our Aussie kids' performances?

Could be the best ever! No flashy results/medals this time - bot overall - the team has done extremely well. Earning rating points in junior events is superhard and we got 3 players earning 40+ points!
Furthermore, not a single player performed below his/her rating (i do not think -4.40 is really such a big deal).

06-10-2014, 11:05 AM
Yes, a fine job from an under-rated team.

How good is it to obtain 116 points like Zhilin did, or 40 odd points like Tom did?

07-10-2014, 12:52 PM
Really good performance by the Aussie team. Well done!

Of course it's a great performance! Well done to the team. Those rating increases would've been really helped a lot by the 40 K factor (in which case you can gain up to about 40 points in one game :O - or on the other hand, lose that much per game!). I think juniors tend to improve very fast though, so this means you'll no longer see many (FIDE) underrated juniors anymore :P

I'm curious if this is statistically true (how much faster U18s on average improve in rating to adults), because I'm assuming the reason why they increased the volatility of the FIDE ratings of juniors is because they tend to be underrated and it takes a while for their rating to catch up to their performance level. I suppose the faster improvement would probably be because of brain development and/or less study and work commitments which means they have considerably more time to study and practice their chess.

Here is some feedback from the latest newsletter of Box Hill Chess Club :
Jamie Kenmure managed to observe the progress of our members at the World Youth Chess Championship in Durban SA while undertaking his arbiter duties. Hopefully in future editions we will get other narratives. Report on the WYCC 2014 (by Jamie Kenmure) BHCC was proudly represented once again on the international arena with 4 players: Christopher Lim, Cassandra Lim, Licia Yao and Zhi Lin Guo.

All members of the club scored gains to their FIDE ratings and a special mention should go to Zhi Lin Guo who gained a massive 116 ratings points
just from the World Youth in Durban, South Africa.

Christopher Lim played in the under 8 boys, scored a good 6/11 points and won his game against the only rated player he played.

Cassandra Lim, Christopher’s sister had a tournament, gaining 11 rating points and had a win over the 3rd seed in the tournament in the under 10 girl’s section. Well done Cassandra!!

Licia Yao showed the world that she can also match it with tough competition after beating the 9th seed in the 2nd round. Great effort Licia and many
more things are to come from this talent in the future.

We move onto the biggest giant of the WYCC, Zhi Lin Guo. I remember watching Zhi Lin this year during the minor event and she was in great form then. Gaining 116 rating points (K factor is 40 for juniors) and winning against 3 players with an average rating of 1900 in a row which included a WFM from Belarus. Overall, it was a great performance from BHCC and all members should be really proud of these efforts. These players will be a force to reckon with in the coming years.
