And also well done Nisipeanu! Jul-05-15    plang: <epistle: Kramnik has a chance to tie Caruana here.> Yes, but that would still only be good for 2nd place Jul-05-15    AylerKupp: <Tiggler> There is no requirement for 30 games: even the first round of 4 games could be tested. The power of the test improves as the number of games increases, that's all.> You can certainly do a chi-squared test with any number of games > 2, but that doesn't mean that the results are meaningful with a small number of games. The actual number of games needed to establish statistical significance and reject the null hypothesis varies but, as you yourself said, the power (accuracy?) of the test improves as the number of games increases. Jul-05-15    kurtrichards: Congratulations, Fabiano! Jul-05-15    LucB: Well done Fabiano! His first victory as an American! ;-) Jul-05-15    AylerKupp: <Tiggler> There is no requirement for 30 games: even the first round of 4 games could be tested.

Jul-05-15    AylerKupp: <<visayanbraindoctor> If Elo himself wrote this, he is clearly saying that rating inflation exists.> I fail to see how any of your quotes have anything do to with ratings inflation, much less that Dr. Elo is clearly saying that rating inflation exists. Perhaps you should re-read sections 3.5, 3.6, and 3.7 addressing ratings <deflation> where he says (section 3.54) "Thus to maintain pool integrity, a mechanism must be built into the rating system to feed in (Rq – Ri) points for each and every player who enters the pool. If this is not done, the result will be <systemic deflation>, a gradual downward trend of all ratings, including those of players whose proficiency remains stable." So what Dr. Elo is really saying is that his system will result in ratings deflation, not inflation, unless steps are taking to prevent this. And all that tinkering with the system are perhaps (not always if politically motivated) attempts to do that. Jul-05-15    Kasparov Fan: Congratulations to Fabiano Caruana great performance by him By the way does anybody know when is the next big tourney Jul-05-15    joeyj: check here ... Future Events: http://2700chess.com/?per-page=100 Jul-05-15    AylerKupp: <Kasparov Fan> Well, <joeyi> beat me to it, but that would depend on your definition of "big". But certainly the Sinquefield Cup 2015 starting on Aug-21 and the World Cup 2015 starting Sep-10 should be considered "big" events. In fact based on their current live ratings (which will change somewhat), the Sinquefield Cup 2015 tournament might be the strongest of all time, with 9 out of the top 10 players (only Kramnik will be missing) participating.

Jul-05-15    whiteshark: Amazing finish by Caruana! Jul-05-15    jphamlore: The way Kramnik is having to try to win games these days, one endgame marathon after another, he would at his age have to become the greatest endgame player in history to have a shot at regaining the world championship. Jul-05-15    Kasparov Fan: Great performance by Nisipeanu, He has played really well all throughout the tournament. His game against Naiditsch a great performance from the black side of a Caro Kann. Jul-05-15    john barleycorn: Congratulations to Caruana. Except for the slip in rd 2 a convincing performance. Liked the last game against Nisipeanu who had a good tournament, imo. Jul-05-15    jphamlore: The end of the So - Kramnik game is showing once again why a 90-second increment from move 1 is needed for normal time control. It's not right to have these endgames spoiled by a 30-second increment. Jul-05-15    alexmagnus: <AylerKupp> Talking about ratings deflation in a system not disturbed, this is what actually did happen once. Back before 2001, with the German national ratings. The ratings got lower and lower, until dozens of players had the minimal possible rating, 1. In 2001 they upped all ratings but changing the formula so that your <first> rating cannot be below 700, no matter how badly you did in your first event. So that now ratings are stable - even if at cost of having a very low predictive value below ~1100. Jul-05-15    Marmot PFL: I did bet on So today but I didn't think this ending would be won. Jul-05-15    john barleycorn: <jphamlore: The end of the So - Kramnik game is showing once again why a 90-second increment from move 1 is needed for normal time control....> 120.5 second increments might be even better to deliver quality endgames. Jul-05-15    jphamlore: <Marmot PFL: I did bet on So today but I didn't think this ending would be won.> This time control is just a disgrace for high level chess. Multiple adjournments as in the old days was perhaps excessive, but why have endgames spoiled like this with players only given about 45 seconds to think. Jul-05-15    Marmot PFL: The way Kramnik played I doubt it would matter. More time would just delay the inevitable. Jul-05-15    Penguincw: Final game on the day (Naiditsch-Meier) is drawn after 77 moves and nearly 7 hours of play. Jul-05-15    fgh: <Penguincw: Final game on the day (Naiditsch-Meier) is drawn after 77 moves and nearly 7 hours of play.> Don't stop there! It was also played during round 7 and in the 7th month of this year! :-) Jul-05-15    Penguincw: Combined (and including this game), both players have 7 draws. :) Jul-05-15    lainulo: Final tally: Fabiano Caruana 5.5/7 Wesley So 4/7 Liviu Dieter Nisipeanu 4/7 Vladimir Kramnik 3.5/7 Arkadij Naiditsch 3/7 Ian Nepomniachtchi 3/7 Hou Yifan 2.5/7 Georg Meier 2.5/7 Wesley won his first game against Kramnik- a feat Kasparov could not accomplish in their WC match a long time ago- that was enough to give him a second place finish and catapults him to seventh in the live rating list ahead of his vanquished foe: 7 ↑1 So 2779.1 8 ↓1 Kramnik 2776.6 http://2700chess.com/ His twin losses coming from lower rated nemesis of local descent. He was being generous to the home and host team. Among his feat was the conquest of eventual tournament winner and new american chess player Fabiano Caruana- Wesley is sending a clear and strong message to the US federation - you give me my stipend too! Meanwhile, adopted mother Lotis would be more than happy to have a last tour of Germany to complete her shopping list before they begin that long trek back to Minnesota. She wouldn't give Wesley back to his real parents yet- why forfeit opportunities for free travel and leisurely shopping with Wesley. Next stop for Wesley: 2015 Metropolitan & ACA Summer Chess Camp July 22-26, 2015 Wow! another prestigious event to get them elo points. Go go Wesley.
