It's now a draw by the looks of things, but probably not an easy draw...
After move 61 - remove the b-pawns and the tablebase says it's winning; remove the g- and h-pawns and the tablebase says it's winning. So the actual position must be winning.

I'm not sure that's 100% foolproof as it's White that has to organise the exchange. I'll predict a draw anyway, but very happy to be shown otherwise!

After Luke's frustration v. Caruana, if you have unsated appetite for further wall-banging, take a look at Arkell - Kashlinskaya. Similar frustration

Round 6 pairings. Luke is Black v Wang Hao. Seven players in the lead with 4/5. There is a nice tweet from Chess 24 "Shirov is the "lucky" leader who wasn't paired against another leader :)"

1 2 GM Caruana Fabiano 2812 4 4 GM Fedoseev Vladimir 2664 47
2 48 GM Maghsoodloo Parham 2664 4 4 GM Grischuk Alexander 2759 7
3 15 GM Wang Hao 2726 4 4 GM McShane Luke J 2682 34
4 1 GM Carlsen Magnus 2876 3½ 4 GM Shirov Alexei 2664 49

Still a decent chance that Magnus will win this

There are no playoffs, a terrible shame in my view.

For tiebreaks they are using Average Rating of Opponents excluding the lowest. The only merit of this otherwise indefensible system is that players can work out where they stand before the final round.

If the top two (2) or more players score the same points, the tie is to be decided by the following criteria, in order of priority:
a) Average Rating of Opponents Cut 1 (AROC 1)*
b) Buchholz Cut 1;
c) Buchholz;
d) Direct encounter between the players in tie;
e) Drawing of lots.
* All forfeits and byes will be cut from the calculation of AROC 1. If a player has one or more forfeits or byes, then no additional
results will be cut from the calculation of AROC 1.
All tie-breaks will be calculated as described in C.02.13 of the FIDE Handbook

Ta to both. Re: Nick's answer, wouldn't playoffs allow too much room for people to play the Swiss Gambit?

In a tournament such as this, I doubt that it ever makes sense deliberately to drop points. In the last couple of rounds, what would you prefer to have to do, draw with 2780 opponents or defeat 2700 opponents?

Well kind of, but with a playoff it might be more productive to play conservatively than it would be without it? Because you can come out of the bunch in a way you couldn't if you were looking at a rubbishy tiebreak score.

Maybe there’s an argument that you should get to include your own rating in the calculation, akin to category norms under old title regulations. I don’t see that this tie break is so terrible - why shouldn’t high performance be a determining factor?

It seems better than a playoff at rapid, and possibly blitz, time controls, maybe even an armageddon determining the Candidates place
