Over at Singapore, the former FIDE Secretary crossed over 2300 apparently without any records of having any such TPR?? Gained the FM title and later FST. Is there any loophole in the FIDE rating system?
He’s 14 years old. Most phenoms shoot up in ratings at this age, when they begin to compete against many GMs. Wei Yi was rated much higher at the same age but yes, Parviz’s improvement in the last few months is impressive.
But I don’t think he has played a GM recently, or even an IM and has achieved this rating by beating players 1700-2100!! A few draws with players rated below 2000 is unlike any other 2500 player in excistence.
He gained 200+ points each in November and January, which means he had an exceptional number of wins in October and December. They should recheck his tournament results in those months. He played in the World Juniors in August, where he was 7-2 but played mostly 1900 and 2000 players. There is some mathematical improbability here. Seems unlikely that he suddenly beat a lot of GMs in the next 4 months.
The 40x K-Factor that FIDE changed to around May/June in 2014 is boosting ratings artificially (without playing strength), and allowing for manipulation. The 20x K-factor after reaching 2299 is also much higher than the standard 15x K-factor that was used traditionally for all rating levels below 2400. Here’s a quick way to make use of FIDE’s Cheat the System – Make sure u keep playing 40x tournaments; then when u cross 2299 hope and pray that the tournament doesn’t go to FIDE on time (delayed in this case by many months); continue playing at 40x K-factor and you will cross Magnus soon, despite never having a rating performance of 2300 or 2400. Also, in this case the player Won or Drew 15 games against higher rated players. Not a single loss. This is Odd, to say the least, when prior performance didn’t indicate any such strength. FIDE’s way to create hundreds of 2300s and 2400s. and tens of 2700s and 2800s, all with 40x K-factor. All chess players prior to Summer of 2014 who toiled and reached 2300 and 2400 level are being made out to be SUCKERS!
Anon 12:02’s post is a good observation. FIDE’s K-factor is 40 for all players under 18 years old with a rating below 2300. Note that Gasimov’s December rating is 2295, allowing him to enjoy K=40 up to his January rating.
The rating change for a given month is equal to K x (Actual Tournament Points – Expected Tournament Points). If you’re expected to score 6 pts in a 12-round event (based on your rating) and you scored 7 pts, you gain 40x(7-6) or 40 rating points. If you unexpectedly scored 11 pts in the same event, you gain 40x(11-6) or 200 rating points! Note that if Gasimov’s December rating happened to be 2301 (instead of 2295), K=20 would have applied and he would have gained only 111 points and not 222, and his rating would have been only 2406 in January.
The lucky part for Gasimov is that K=10 applies to all players 2400 and above. Thus, even if he starts losing games now, his downward adjustment may not be as fast. However, his expected score in tournaments will also be considerably higher. If he enters a similar tournament as above, he may now be expected to score 9pts. If he scores 7, his rating change is 10x(7-9) or -20 points.
In short, Gasimov may have improved but may have also been lucky at the right time, and not as phenomenal as it appears.
