Cannot find your name in the fide list and they certainly should have also non active players who played 10 years ago unless your name is written
Ljudmil Tzvetkov and in this case you have a fide rating of 2095.

https://ratings.fide.com/card.phtml?event=2905850

If this is your name then
in your last tournament in 2006 your score was 1 out of 4 and you lost 16 rating points.
What do you want to say? Are you doubtful about Lyudmil's abilities? He said:
If I nowadays appear in a tournament, I am certain I will soon pass 2400-2500 effortless
And he is probably 2600-2700 level in good conditions:
in a back room with quiet conditions I play much stronger though.
More respect for top players, Uri, more respect.

Uri, you can see from his play that he's clearly a strong player.

If this is your name then

I suppose that is me.

That was in February 2006 at a tournament where we played at a hotel, and downstairs a sumptuous and very loud wedding was going on. So I performed bad.

My last tournament was only for Bulgarian rating, and was played in early March 2006. This time they had a small but very quiet hall for a venue, and taking advantage of this, I scored 5 out of 6, to finish joint first, and winning in the process against at least one GM, one IM, and maybe one or 2 masters. If you are curious and know sufficient Bulgarian, you migth want to check the site of the Bulgarian chess federation, under tournaments for the respective year, probably they still have it, some info migth even be available in English.

But they will have at least rankings table for the tourney.

It has always been like that with me: whenever it starts getting loud, I make a mistake and lose.

I am supposed to be a Bulgarian candidate master from the distant year of 1998, but I do not know if this is somehow valid; in any case I fulfilled the norms.

@Kai: thank you, Kai, at least one person trying to support me. :)

I seemed to see a bit of sarcasm...

You seem a great analyst, you have patience to analyze and knowledge, his compendium is a great document.
But playing chess live and legally is another thing, those who have experienced it know it.
Positions must see them in mind, imagine them, they can not touch parts do not take back.
You despiseth to the GMs, you not have modesty.
You teach two games where it says win, doesn't teach us their tricks and their lost games.

In Spanish it is said "dime de que presumes y te dire de que careces"
"tell me that boast and you dire that you lack"

Sorry, could not find the particular tournament. On the site of the Bulgarian chess federation they have kept only the most important tournaments from 2006, and on the site of chess club "Ivis" in Sofia, where the tournament was played, they started archiving one month later, since april 2006 :)

It proves the last tourney I have been playing in was a rapid in April 2006.
Site is still up: http://chess.slivnitsa.com/slivnitsa-open-2006

Go down the page and you will see a rankings table. In Bulgarian, my name is written like that:
&#1051;&#1102;&#1076;&#1084;&#1080;&#1083; &#1062;&#1074;&#1077;&#1090;&#1082;&#1086;&#1074; (13) 2202 &#1057;&#1055;&#1040;&#1056;&#1058;&#1040;&#1050; &#1055;&#1051;&#1045;&#1042;&#1045;&#1053; XXI &#1055;&#1083;&#1077;&#1074;&#1077;&#1085; 5,5

I did not perform particularly well here, but 5.5/9 is also not a disaster.

It always happens like that: what you are looking for is gone, and the things you do not need pop up on the screen. :)

Do you have any online blitz or rapid rating? Those are usually reasonably close to FIDE ratings if properly scaled, depending on the server and the game type. Not so accurate for old guys like me, but probably you are not old.
Anyway, if you want to make a real contribution to computer chess, you might enjoy the following: Play ten game matches against komodo with various handicaps, but keeping Contempt at 80 and giving yourself twice (or three times, whatever you like) the 2' + 2" you give to Komodo. The important thing is to use the same time control for all matches, and to observe it strictly. I think it's okay to resign games for the computer if you are up 5 pawns equivalent and computer doesn't have a queen. Computer's analysis should be hidden.
The idea is to compare your score at different material handicaps, to get more information on how hard or easy they are relative to one another. You could try all of the two pawn handicaps where White removes b,c,d,e, or f pawn (so ten handicaps), as well as f7 handicap, f7 + 2move handicap (White plays 1e4 and it is still White's turn with no f7 pawn), and Exchange handicap ("a" rook for "b" knight, moving "a" rook to "b" square, try with both colors). Of course there are other options.
Note that this test would be interesting for anyone with a blitz or rapid level above 2200 FIDE. As long as the matches are reasonably competitive, they can be compared. If they are too one-sided, you are giving yourself too much or too little time.
Komodo rules!

Larry, you assigned me task-load for a year ahead. :)

I do not play online, too many cheetahs there.

At some point I migth try what you suggested, however I hate losing games on time with a winning position, because either you have to make a move, which might be bad, or your time will expire. Current top engines are not like those of 10 years ago, when you migth play a range of weak moves, and still win. Any bigger mistake is punished. That is why I do not set myself TC: there are positions so complex for a human, that one must think on them a minute or 2 not to make a huge blunder. And they are not so rare, unfortunately.

I think any TC lower than 20' + 10'' is simply suicidal against modern tops.
At 20' + 10'' vs 5' + 3'' for Komodo I am not afraid to play against Komodo with or without handicap. As said, any lower TC for me is simply suicidal.

I prefer to play with more time and no handicap than with some handicap and short blitz TC. Too many complex positions there, created by the top engines...

At some point I migth try some of the suggested positions, but not rigth now.

That would be interesting. Can you play without handicap and without seeing engine's output at 120 min + 1 min for you and 1 min + 1 sec for Komodo on one core? Strictly observing the clock and not taking back? If yes, post the games.
