Have you got an accurate score of our round three game? I was so short of time that my recording finished with about two minutes to go which it should'n't have but it would be a great game for folks to analyse. Typical major game where both players have to win.

Running through the games it was deeply flawed with too many mistakes by both players.
Key question for both players to ponder is "how did I play so badly?
Worst mistake of the game happened in this position.
With black I had two candidate moves 23 ..... Qxa4 and 23... Qxc7. The rook had just gone to c7 - possibly the 2nd worse move of the game.
The c7 capture looked fine, I spent much more time on the a4 capture and played it
There followed
24 Bb1 Bd4
25 Bxd4 Qxd4
26 Qxd4 Nxd4
and Black thought this was winning with the king able to survive the attack by three white pieces.

27 Re1 Aha missed that - now 4 white pieces attacking - Black could be in trouble
27.... Nb5
28 Re7 b6
29 Nh7 Kg7 ?
30 Re5 Rd8
31Rg5+ Kh8
32 Rxf7 Ra7
33 Rxa7 Nxa7
34 Rxh5
White moves 28 to 34 were very strong
Recent black moves ...could do better.
Black is in big trouble

34.... Nc6
with hope that the discovered check is survivable.

Fritz prefers Nf6 + neither player knew this at the time.
35...Kg8
36 Rh6 Nd4
37 Rg6+ Kf8
38 Kf2 Ke7 ?
39 Kg3 ?
Time trouble mistake
both players missed N fork if the Black king gets checked onto d6

Black short of time now and fortunate that this strong move is easy to find - no need to work out reply to each possible white response.

42 Kf2 Nxf4
ditto
43 Rg7+ Kf6
And this time I did look at all legal white moves before moving K to f6.
Lucky to have such a strong move available here.
