The organisers have a policy that all players pay for their entries, including Grand Masters. As a result, only one GM turned up! Given that the GM was Mark Hebden, one would think that the result was a foregone conclusion. Amazing then that Mark only made 3.5 and didn't figure in the prizes at all! The following game was primarily responsible for this.
1.d4
e6
2.Nf3
c5
3.e4
cxd4
4.Nxd4
a6
5.Nc3
Qc7
6.Be2
Nf6
7.0-0
d6
8.f4
Nbd7
9.Bf3
Be7
10.g4
h6
11.Qe2
g6
12.Be3
e5
13.g5
Well I guess it would be a shock if Mark had not tried to mix it up rather than play the natural 13 Nb3. However this move seems to loose a clear pawn without any form of real compensation. But as the sun comes up every day and sets every evening we have all got used to Mark winning regardless of material considerations.
13...hxg5
14.fxg5
Nh7
15.Nd5
Qd8
16.Nb3
Bxg5
17.Bg2
b6
18.Nd2
b5?!
I am not sure why Black gives White a target for some queenside counter play. 18...Bb7 seems more solid with an undisputed advantage.
19.a4
Bb7
20.Bxg5
Nxg5
21.axb5
Bxd5
22.exd5
axb5
23.Rxa8
Qxa8
24.Qe3
I can't fathom out why White didn't play 24 Qxb5 here. Perhaps Mark was concerned about 24...Qa7+ 25 Kh1 Qd4 but the simple 26 Qc4 equalises.
24...Rh5
25.c4
b4
26.h4
Rxh4?
Definitely temping but certainly incorrect. 26...Nh7 was the right move and Black is still better.
27.Qxg5
Qa7+
28.Rf2
Rf4
29.Qg3
Presumably Mark was trying to swap all he pieces off into a winning endgame otherwise he would have played the superior 29 Ne4.
29...Nf6
30.Bf3
Qd4
31.Kh1
Qxb2
32.Re2
Kf8
33.Kg2
Qd4
34.Qf2
Qc3
35.Qb6
Ne8
36.Qa7
Nf6
37.c5??
g5??
37...e4! wins but doubtless both flags were hanging here.
38.Kg1
g4
39.Bg2
Qxc5+?
39...Qd4+ 40 Kh1 Qd3 wins immediately.
40.Qxc5
dxc5
Reaching the time control. Despite the errors Black still is close to winning.
41.Rxe5

42.Ne4

43.Nc5
