  Messiah: Roebers managed to beat the much more experienced Erwin L'Ami! Fantastic performance!
Jan-15-23  ndg2: Eline Roebers beats Erwing L'Ami in a surprise upset.
Jan-16-23  ultrausurper: Why did Vaishali resign against Donchenko? I'm do confused...
Jan-16-23  goodevans: <ultrausurper> Good question. I've done my best to answer it in the game itself - R Vaishali vs A Donchenko, 2023.
Jan-16-23  goodevans: But then <ndg2> has provided a better answer in the same place!
Premium Chessgames Member
  Messiah: The Beerdsen-Pechach is an Evans! Might be a superb game.
Jan-16-23  goodevans: <Beerdsen-Pechach is an Evans! Might be a superb game.>

Exciting anyway. But with Beerdsen having missed two wins in the first 25 moves, I doubt Pechach will give him a third opportunity.

Jan-16-23  ndg2: Pechac had a win against Tabatabaei in move six but threw it all away: Pechac vs M A Tabatabaei, 2023
Jan-16-23  ndg2: Against Warmwedam Eline had at one point again a winning game (67..Kf3!). Sie took the pawn and the game was a draw.
Jan-18-23  goodevans: Oh, Eline Roebers!

Such a talent but she really needs to learn a thing or two about time management.

She just blew another win and this time she didn't even get a draw from it.

Totally demolishing Thomas Beerdsen but chose to use up nearly all of her time on move 19 when in fact there were multiple ways to win handsomely. Played the rest of the game more-or-less on the increment and blundered from win to loss nine moves later. So sad (unless you're Beerdsen, of course!).

  Messiah: Schitz, I missed that round 5 is played today. Anyway, let's check the remaining games live.
Jan-19-23  ndg2: ^Yes, this was painful to watch. The malaise of having too many promising moves without any of them being a clear, immediate win while opponent still has some traps and counterplay.

I was there in quite some games.

Jan-22-23  ndg2: Upset in round 7: Vaishali wins against Supi (2600) in a game with many missed chances for both players.

Round 8 will be exciting. Eline has white against Vaishali. I think Elines real playing strength is close, if not higher than that of her opponent.

Jan-22-23  goodevans: The nightmare continues for Jergus Pechac. Rock bottom with +1 -6 =1 after losing today to Ivic, rated 50 points below him at the start of the tournament.

It could have been even worse had Beerdsen converted the winning position in their draw and at least Pechac's last three games include the three players immediately above him in the table giving him a reasonable opportunity to avoid the wooden spoon.

  0ZeR0: <goodevans>

Most unfortunate (for Pechac)... you win some and lose some. And don't I know it (especially the losing).

Jan-27-23  ndg2: Yilmaz and Donchenko in the race.

It seems that in the last three rounds Yilmaz has the much easier opposition: Pechac, Supi, Roebers (Yilmaz) vs Tabatabaei, Beerdsen, Ivic (Donchenko).

But Pechac and Supi are stronger than their score so far suggests. And Donchenko should make a full point against Beerdsen at least.

Premium Chessgames Member
  Messiah: Possibly I am completely wrong, but Supi's opening reeks of being unprepared.
Premium Chessgames Member
  0ZeR0: Big win for Donchenko today over Tabatabaei with Yilmaz "only" managing a draw against the one win (but still dangerous) Pechac.
Premium Chessgames Member
  Messiah: The Beerdsen-Donchenko (0-1) was unusual.
Premium Chessgames Member
  MissScarlett: Yilmaz has Black against Roebers tomorrow, so it's likely that Donchenko, the 24 year-old ̶R̶u̶s̶s̶i̶a̶n̶ German, will need at least a half point against Ivic to secure his passage to next year's Masters.
Premium Chessgames Member
  whiteshark: A last round can bring miraculous things...
Jan-29-23  ndg2: With his win over Thomas Beerdsen in round 12, Alexander Donchenko secures first place in the Tata Steel Challengers (2023) tournament with one round to spare.

Even if he loses against Ivic in the last round and Yilmaz wins against Roebers, their direct encounter (1-0 for Donchenko) makes him the winner prematurely.

Premium Chessgames Member
  MissScarlett: Tiebreaks for the Challengers, but not the Masters?
Premium Chessgames Member
  whiteshark: A fighting last round - all 7 games were decisive! Congrats to Alexander Donchenko to the tournament win
Premium Chessgames Member
  0ZeR0: Congrats to GM Donchenko! He was clearly the strongest player in this group and has earned his spot in next year's Masters tournament.
