Tactics Rating

Hi, I would like to know if you can compare ELo FIDE real with the rating in tactics that one has on Chess.com.

If a player has an 2000 ELO in tactics, what could be an estimate of his ELO Fide?

No, one's tactics rating here isn't likely at all to be an accurate gauge of what one's FIDE Elo rating would be.  

(In fact, even your Daily or Blitz, or whatever other variant, rating on this site isn't necessarily a good gauge of its equivalent in FIDE or USCF OTB play.)

Firstly, chess.com doesn't use the Elo rating system, they use the Glicko.

Secondly, the tactics trainer here has undergone a lot of changes in the past several weeks, so people's tactics ratings have been all over the map lately; the most recent trend seems to be that they're now quite inflated for most players when compared to their actual game ratings.

If your tactics rating is under 3000, and you've actually used the new tactics trainer for a good number of tactics, an approximate formula is:

Tactics Ability elo = Chess.com TT rating - 700.

If you keep using the Chess.com TT, then change the formula to the following, after a few days:

Tactics Ability elo = Chess.com TT rating - 1000. 

The sad thing is, this is hardly a joke. 

Thanks!!

Before the change my tactics rating was 1850-1900. My OTB is 1555 currently and have been up to 1648 at my most recent peak.  With the TT changes, I'm over 2300 here right now

Either way, 1850 - 700 isn't accurate, and certainly not -1000. My OTB most closely tracks with my Rapid here, at 1479 but that isn't based on very many games really. But, that is just one data point; some people might be closer to their OTB on one rating or another here, some will be higher and some lower (some a lot on either side).

Thanks Martin, My tactics rating here is 2050 and I think it will be up in the next days. I practice a lot of exercices every day , maybe an hour per day however it´s very hard to increase in chess.com and I imagine that it must be harder OTB...

The tacticsscore can not be compared to fiderating. Its very different, and the new system makes the score climb wild and high.

Blitzrating is closer to fiderating, but fast players  does better in blitz and slow players does worse. My blitzscore has been at the same as my fiderating, but is lower now.

Let me point out something I mentioned in another thread. The reason for the huge difference in ratings is because Tactics doesn't gauge openings. Openings are boring and take years to memorize the lines. I never had the patience to do the work it takes to become a 1900 rated player at openings. I have only played 1 minute and a little 3 minute chess for years, so I am a quick study on assessing what is happening, which helps since time is a factor. If you can't hold your own on openings against a 1900 player you will never get to the mid game with equal material, or position and be destroyed. We can all agree that the more pieces on the board in Tactics makes for a more difficult problem. There is much more to assess and the clock is ticking, with only seconds, rather than minutes to spare. Being able to do that not only shows you have what it takes, once you learn the opening lines, but it also shows anyone looking at your profile you are not a computer. They even show you in the details how each tactic is rated, so you can raise your rating rapidly by nailing a bunch below your rating, but as you go up, so does the difficulty. As any computer will tell you, openings are the bane of chess, which is why the programmers had to cheat and give Deep Blue an opening library (written by millions of chess players over hundreds of years) to finally beat Kasparov. Bottom line, if you want your FIDE to match your tactics, you need to work on your openings. Bobby read over 4000 books to get there. With computers the kids have it much easier, but still takes a ton of commitment.

I'm sure no one will listen to me, but... I heard a suggestion earlier -- it was offered on another thread -- that chess.com should eliminate the rating on TT. I don't know if I fully agree, but the TT rating means nothing. I have a rating of 1995 [I think??] on TT, but my rating on daily is 1853 [?], and then you look at bullet, upper 1300s. Give me 3 days [daily] to come up with a move and I'll find one. But give me mere seconds... I'll either blunder like a fool or forfeit on time in a completely won position. The rating on TT is merely a measure, and possibly not a good one, of how consistent you are at solving tactics, getting it right. I had a TT rating of 1433 in 2015 [?]... My big problem? I was trying to beat the target time, making clumsy fast moves. My rating started soaring when I slowed down! 

That can already be done with unrated tactics. You can even define the rating ranges. I don't know if all the stats are tracked in that mode though.

 edit: nope, stats aren't tracked. It would be nice if the tactical themes were tracked in both modes.
