Palmerston North Qualifying Tournament

After 4 round's M. King (yes that's me writing about myself?!) is leading the event wi th a perfect score followed closely by S. Holdaway, S. Taylor and J. Kim on 3. The top seed and current Palmerston North Champion is alone in fifth place on 2.5 and even has chances to miss qualification if he loses his last round game!
J. Kim curently in 2nd equal has made promising progress and is clearly one of Palmerston North's most gifted juniors.

The main line is 7...c6 8.Qd2 Nbd7 9.Rd1 (9.0-0-0 a6 10.Kb1 b5 11.Nc1 exd4 12.Bxd4 b4 13.Na4 c5 14.Bxf6 Bxf6 15.Qxd6 Be7 16.Qg3 Bh4 17.Qh3 Be7 18.Qg3 Bh4 19.Qh3 ½-½ Kramnik,V-Kasparov,G/Linares 1993/ ) 9...a6 10.dxe5 Nxe5 11.b3 b5 12.cxb5 axb5 13.Qxd6 Nfd7 14.f4 b4 15.Nb1 Ng4 16.Bd4 Bxd4 17.Qxd4 Rxa2 18.h3 c5 19.Qg1 Ngf6 20.e5 Ne4 21.h4 c4 22.Nc1 c3 23.Nxa2 c2 24.Qd4 cxd1Q+ 25.Kxd1 Ndc5 26.Qxd8 Rxd8+ 27.Kc2 Nf2 0-1 Karpov,A-Kasparov,G/Linares 1993/

h5?
Black tries to slow down white's attack by closing down the h-file, best was to go for the counter offensive with 11...c5 I was put off this move because of the hole it leaves on d5 and the weak d6 pawn but black is able to prove with 11....c5 that white has weaknesses of his own to worry about.
11...c5 12.Nc2 (12.Nb3 Be6 13.g5 Ne8 14.Nd5 b5÷ Black is atleast equal)
12...Be6 13.0-0-0 (13.b3 Nfd7 14.0-0-0 b5 White's position is now over extended for example 15.Qxd6 bxc4 16.f4 cxb3 17.axb3 Nxg4 18.e5 Qh4-+)
13...Nxc4 14.Bxc4 Bxc4 15.Qxd6 Qxd6 16.Rxd6 This is a possible line 16...Rac8 17.h4 h5 18.g5 Ne8]
12.gxh5 Nxh5 13.0-0-0 Bd7 14.Rdg1
Better is 14.Bg5! Bf6 15.Bxf6 Nxf6 16.f4 Nc6 17.h4 White's attack is crushing here.
14...b5!
One of the common break through ideas trying to expose white's King.


15.f4
Openig up the Queen side is suicide as can be seen from the following analysis.
15 cxb5 axb5 16.Ndxb5 Bxb5 17.Nxb5 Rxa2 18.f4
A) 18...Nc6 19.Bxh5 Qa8!! Black is winning with a sudden attack helped from afar by black's strong g7 bishop.
A1) 20.Qd5 Rxb2 21.Na7 Nb4 22.Qxa8 Rxa8 23.Bf3 c5 24.e5 Nd3+ 25.Kd1 Rxa7-+;
A2) 20.Nxc7 Qa4 21.Qc2 Bxb2+ 22.Kd1 Ra1+ 23.Kd2 Qa5+ 24.Ke2 Qxh5+ 25.Kd2 Rxg1 26.Rxg1 Nd4! 27.Qxb2 (27.Bxd4 Bxd4 28.Rg5 Qf3-+) 27...Qe2+;
A3) 20.Nc3 Ra1+ 21.Kc2 Nb4+ 22.Kb3 Rxg1 23.Rxg1 Rb8-+;
A4) 20.Bf3 White cannot hold onto the piece because black's mating attack will cost white his queen. 20...Ra1+ 21.Kc2 Qa4+-+; B) 18...Nxf4 ]
15...Nxc4 16.Bxc4 bxc4 17.f5
White's attack looks visually menacing but in fact black is not even worse in this position.
17...c5 18.Nf3 Qa5?!
18...Bc6 19.fxg6 fxg6 20.Qe2 Black has a pawn but his king must always be looked after (20.Rxg6? Rxf3) 20...Bxc3 21.Qxc4+ Kg7 22.Qxc3+ Qf6
19.fxg6 fxg6?
19...Bxc3 20.gxf7+ Kxf7 21.bxc3 Bc6 White only has a slight edge according to my computer but what human would play in such a way.
20.Rxg6?!
20.Qd5+ Kh8 21.Nh4-+ And I am sure this is only one of many winning moves
20...Be8 21.Qd5+?!
21.Rxd6 Rxf3 22.Qd5+ Kh7 23.Qxa8 Rxe3 24.Qxe8 Rxc3+ 25.Kb1!+-

21...Bf7 22.Qxh5
Better is 22.Rxg7+ Nxg7 23.Qxd6 Rfe8 24.Ng5 Be6 25.Rg1 Qd8 26.Qe5+-
22...Bxg6 23.Qxg6 Rxf3 24.Rg1 Ra7 25.Qe8+
25.Bh6 Rxc3+ 26.bxc3 (26.Kb1 Qa4 27.bxc3 Rb7+ 28.Ka1 Qc2 29.Qe6+ White must force a perpetual.) 26...Qxc3+ 27.Kd1 Qa1+ 28.Ke2 Qb2+ 29.Bd2 Re7
25...Rf8 26.Qe6+ Rff7 27.Bh6 Kh7 28.Bxg7?!
Trading pieces just releases the tension and make's black's defensive task easier. Better is 28.Qg6+ Kh8 29.Qxd6
28...Rxg7 29.Qf5+ Kh8 30.Qf8+ Kh7 31.Rxg7+ Rxg7 32.Qxd6 Rg1+ 33.Nd1 Qe1

34.e5?
Perhaps over confident with his 100% tournament record at the club this year white makes a bad decision, Davis had to force a draw with his numerous check's starting with 34.Qd7+=
34...Qe3+ 35.Kb1 Qd3+
With the Queens off black is winning easily.
36.Qxd3+ cxd3 37.Kc1 Rg2 38.b3 Rxa2 39.Kb1 Rxh2 40.Nb2 Rh1+ 41.Ka2 d2
0-1
