Good luck! Cracking win v. Kokarev in rd 6, by the way. 22...bxa4 was a familar line-opening. But its mirror image, 26...gxh5, was inspired - and instructive

Nigel looks to be losing in round 8, though...

[David Robertson]

Not so sure about that. Nigel has plenty of play. Awkward for both sides.

And now the engine evaluation has reappeared (move 52), I'm right - White is only [+0.31]

[Christopher Kreuzer]

Yeah, I can't make head or tail of it.

EDIT: And Nigel winning now.
EDIT: Spoke too soon, a slip from Nigel and it was drawn.

[David Robertson]

Nigel's fatal flaw: he's not made of silicon. Hence, 70...Kg7 was pure carbon. Never mind

[Christopher Kreuzer]

Not sure if the top board being drawn makes that any less tragic. I suppose a draw was a fair result, but Nigel could have been leading if he had seized that chance (he had an earlier chance as well on move 64). I think both players were down to not much more than the increment though. And to be fair, 70...Rh1 was a scary line. Wonder how much of this was seen over the board by either player?

Still a three-way tie going into the last round.

[Nigel Short]

I had food poisoning and was up half the night. Glad that I didn't lose. By the way, we have a fast time-limit of 90 minutes plus 30 seconds. It is not conducive to accurate play in complicated endings.

Good luck in the last round; glad to see you have White.

[Christopher Kreuzer]

Nigel drew. His opponent (and presumably Nigel as well) missed a vicious tactic in a line starting from move 22 that the silicon monster spots immediately:

Nbd6 Ng6 38. Nf5+ Kf6 39. Nce3 Bxe3 40. Nxe3 Ne5+

Nice tactic that. Might make an appearance in some tactics manuals.

(EDIT: Though I'm not sure what the continuation is in the variation given after 25.Kg1 instead of 25.f3... Hope the computer didn't get 'frozen' in bad evaluation by some transmission glitch or the players playing moves quickly.)

The other guy on 6.5 (Surya Shekhar Ganguly) won and wins the tournament.

[Nigel Short]

I haven't switched on the engine yet, but I intended 24. Rf4 and after check, Kg1.

[Christopher Kreuzer]

So: 22... Bd4 23. Rd4 Nf5 24. Rf4, but has the rook got anywhere safe to go after 24...Ne6? Maybe there is some deep line in there where the knights kick the rook around and the tactics all work in Black's favour? *shrug* Without the help of an engine, I'm a bit lost there. Stuck on 25.Nd6.

[Christopher Kreuzer]

Using a fairly rubbish online chess engine, it seems that after 22... Bd4 23. Rd4 Nf5 24. Rf4, the right move for Black is Qb7+ and if White plays Kg1, then Black simply plays Ne4, with the threat of Ng5 and Nh3+ being devastating. The Black knights swarm over the White kingside, while the White pieces are spectating from the queenside. Or something like that. The usual caveats apply.
