Dun Laoghaire Masters 2010 (9)
Hebden wins in Ireland
IM Malcolm Pein - Thursday 2nd September 2010
Mark Hebden took first place in the Dun Laoghaire Masters 2010. Malcolm Pein takes a look.
Mark Hebden won the GM Group of the Dun Laoghaire Masters tournament organised by the Irish Chess Union. Hebden scored 6/9 and his key win was yet another King's Indian brilliancy, against the German GM Klaus Bischoff. The hard work of Eamonn Keogh and his team was rewarded as Irish junior Alex Lpez made an IM norm.
Hebden was in the joint lead with three to play but pulled clear in the last round.

(17...a6 is also played)
18.a4 h5 19.Nb5 Ne8 20.Ra3
(20.Nxa7 Rc7)
20...Bd7 21.Rc3 Rg7 22.h3 a6 23.Na3
(23.Nc7 Nxc7 24.Rxc7 Rb8)
23...Be7 24.Be1 Qb8!?
(Hebden likes this plan, it looks risky to open queenside lines and squares)
25.Qb3 Bd8 26.Qb4 Qa7 27.a5 b6 28.Nc4 bxa5 29.Nxa5 Bb6 30.Kf1
(30.Nc6!)
30...Rb8 31.Rb3 Ne7 32.Ra1
[32.Nc6]
32...Bc7 33.Qa3 Nf6 34.Rxb8+ Qxb8 35.Qb3 Qe8!
(A practical decision, White seems to have lost the thread somewhat and Black prepares a typical KID attack even though White might be better with correct play)
36.Nc6 g4! 37.Nxe5
(It looked risky but 37.hxg4 hxg4 38.fxg4 Nxg4 39.Bxg4 Bxg4 40.Nxg4 Rxg4 41.Nxe5 was better)
37...gxh3 38.gxh3
(38.Nxh3 dxe5 39.d6+ Kh7 40.dxc7 Qg6 41.Bf2 Qxg2+ 42.Ke1 Qxh3)

Position after 42...Ne4!!
43.Qd4
(43.Nxe4 Rg1#; 43.fxe4 Bxh3+ 44.Nxh3 Qxh3+ 45.Ke1 Rg1+)
43...Bxh3+! 0-1
The following game sees Black pursue his queenside play while White attacks the other wing. For a while it appears the players are ignoring each other but eventually White's threats become decisive.

(12.Bxf6 Bxc3+ 13.bxc3 Qxc3+ 14.Qd2 Qxa1+)
12...Ne4
(12...Nbd7 may be best; 12...Nxh5 13.a3 Bd6 14.e3 f5 15.Nxg4!)

(Black has only a pawn on b2 for his trouble and this can be eliminated at minimal cost if required)
23...Nb6 24.Rfe1
(24.exf5 was also strong)
24...f4! 25.gxf4 Na4 26.f5! Qa5 27.Re3 Rb8 28.Ne5 Qb5
(28...Rb3 29.Nxc4 Nxc3 was the last chance to cause confusion)
