Longest Unbeaten streak?

MVLs streak was 67 games, the same as So's. And Wang Yues streak was 85 games in 2008.

But Malakhov has currently a streak of exactly 90 unbeaten classical games.

I also read in somewhere that apparently Sergey Tiviakov claimed to have a 110 game streak in 2004-05, but i can´t verify this since the game info in his FIDE profile is freakin blocked.

Ladies and Gentlemen, I present

DING LIREN

And as for opposition, he does this being in the 2800 club.

Ding Liren is currently 91 games unbeaten, so he is already the second best streak. Impressive, as he played several elite tournaments, including Candidates. He certainly "just" drew most games against the top players, but also managed to beat several.

92 as of today, 2 more rounds of European Club Cup left. On 20th of October, he'll play 9 more games on the Isle of Man.

Emanuel Lasker was likely master of his domain for ~27 years, given this is how long he reigned as World Champion

Lasker was World Champion for 27 years, but he hand picked his opponents in World Championship matches and avoided his toughest opponents (such as Rubinstein and Nimzowitsch). Even so, he nearly lost the World Championship to Carl Schlechter and there's still some argument about whether the match conditions required Schlechter to win by two points. In the last game of that match, Schlechter went all out for the attack even though he was ahead in the match. He lost, the match was drawn, and Lasker retained the title. 

Kasparov played as many World Championship matches (6) in 15 years as Lasker did in 27 years!

I'm unbeaten in daily for 4 months.

But no big opponents and only 4 games.

lol

We might see an end tomorrow, since it will be probably Carlsen vs Ding if both teams put their #1 player in. Lets summarize all unbeaten streaks above 80 games up to this day:

• 110 : Sergey Tiviakov
• 95: Mikhail Tal
• 93: Vladimir Malakhov
• 92: Ding Liren (ongoing)
• 86: Mikhail Tal
• 85: Wang Yue
• 84: Milan Drasko
• 82: Vladimir Kramnik

UwU

I have not heard of Tiviakov and Malakov having such great unbeaten runs before. And even if true, they had weak opposition, likely including many non GM opposition. Wikipedia and all other chess sources make no mention of their streaks either.

You probably should not be counting them.

Finally, Tals streak broken! Ding aka "the Great Wall of China" Liren achieved his 96th unbeaten game in a row, hats off.

@Debistro: While I can´t confirm Tiviakovs streak, I read about it in multiple Articles or comments, the Malakhov streak happened just a year ago, it can be verfied on his FIDE profile. So that makes it:

• 110: Sergey Tiviakov (?)
• 96: Ding Liren (ongoing)
• 95: Mikhail Tal
• 93: Vladimir Malakhov
• 86: Mikhail Tal
• 85: Wang Yue
• 84: Milan Drasko
• 82: Vladimir Kramnik

Congratulations to Ding Liren! And he did it while facing some of the best players in the World! His performance rating for 2018 is the highest in the World, ahead of Carlsen, Giri, and Caruana!

If it had been an American player or Carlsen there would have been a breaking news article on here no doubt, but since it is an 'unfashionable' player they don't bother to even report it yet.

Here is the information on Tiviakov's 110-game streak (taken principally from 365chess).

Losing to Vladimir Georgiev in Round 12 (2004 Oct 28).

1 36th Olympiad (Oct 2004), game is available
9 Calvia Open (Nov 2004), all games available (only 1 on chessgames)
9 Spanish team championship (Nov 2004), 5 games found (not on chessgames)
9 XVII Torre Memorial open (Dec 2004), 6 games found (same on chessgames)
4 XVII Torre Memorial "Wimbeldon" knockout (Dec 2004)
[time controls unclear, lost to Ivanchuk in a quarterfinal playoff]
9 Bad Woerishofen Open (Mar 2005), all games available (none on chessgames)
9 Gausdal Open (Apr 2005), 6 games found (8 on chessgames)
9 Hulia Centenary Open (May 2005), all games available (8 on chessgames)
2 Dutch team championship playoff, both games available (not on chesgames)
5 Lodi open (Jun 2015), all games available (none on chessgames)
13 European championship (Jun 2015), 12 games available (13 on chessgames)
9 European teams championsip (Jul 2015), 7 games available (8 on chessgames)
9 Solsona Open 3rd (Aug 2005), 2 games available (none on chessgames)
9 Dutch championship (Sep 2005), 5 games available (9 on chessgames)
4 Monarch Assurance, Port Erin (Sep 2005), 4 games available (0 on chessgames)

Losing to Shabalov in Round 5 (2005 Sep 28).

This totals 110.

It is unclear that with the Spanish/Euro team championships whether he really did play all 9 rounds.

He also played in various team events (Dutch teams, Bundesliga West, 4NCL) in 2005, though it seems these games were after the loss to Shabalov (he incidentally lost again later in the same Monarch Assurance swiss).

At Gausdal, he beat some guy named Carlsen in Round 1...

I would guess his FIDE card information would have rating details.
He definitely played weaker competition in the open events, but I think almost all of it was (at least) 2200 and commonly 2400+. He did make a lot of short draws against weaker players, particularly with Black.

i think is ding liren with 95 or 96

It's Ding with 97

errr....hummm... NO!

Do you mean, something like this?

And so it comes to an end... Ding "The Great Wall of China" Liren was finally broken, by ze french cannon MVL. He still marked his legendary streak with a century:

• 110: Sergey Tiviakov
• 100: Ding Liren
  
• 95: Mikhail Tal
• 93: Vladimir Malakhov
• 86: Mikhail Tal
• 85: Wang Yue
• 84: Milan Drasko
• 82: Vladimir Kramnik

Bogdan Lalic tells me his streak is 157 games, although some were rated only on a national level.
