(1) Anthony Ker (2420) - Efrain Tionko (1891) [B22]
Wellington Open 2014 Wellington (3.1), 19.04.2014
[Efrain Tionko]

1.e4 c5 2.c3 d5 3.exd5 Qxd5 4.d4 Nc6 5.Nf3 Bg4 6.dxc5
Anthony played ;this same line and lost against William Li at the NZ Championships in January; ;suffice to say that I spent some time studying that game and hoped Anthony ;would repeat!

This is the principled move if black were to ever enter this line, as recapturing on c5 misplaces the queen and gives white a very easy game.

7.Kxd1 e5 8.b4 a5 9.Bb5 Nge7 10.Nbd2 axb4 11.cxb4 0-0-0 12.a3
[12.Bxc6 was played in aforementioned Ker-Li game]

12...Nd4 13.Be2 Bxf3 14.Bxf3 f5
I'd like to claim over-the-board brilliance, but I was actually still in my home preparation here!

15.Ra2 e4 16.Be2 Nd5 17.Bb2 Nxe2 18.Kxe2 Nf4+ 19.Kd1 Nxg2
Diagram I was pretty pleased with the forcing sequence, but I did not expect Anthony's next move.

just for sheer shock value

20...Bxg7 21.Rg1 Bh6?!
[21...Rd3 immediately might have been better 22.Rxg2 Be5 and white might be in a bit of a pickle down the d-file]

22.Rxg2 Rd3 23.Ke1 Rhd8 24.Nc4 Bf4 25.Ke2 Kb8
Just to get away from a potential check, but I'm not sure if this was necessary. The white knight was probably more required to defend than attack

26.Ne3 Rf8 27.Rg7 h6 28.b5
It was at this point that I started to have some serious doubts about my position, as the queenside pawn storm looked really scary.

28...Bxh2 29.c6 f4
[29...bxc6 would probably have been a good alternative if my king was on c8, but in this position, white can activate his queen's rook with tempo: Ra2-b2+]

yup, the king should have stayed on c8

30...Kc8 31.Nc4??
Fritz flagged this as a losing move for white, but over the board I thought it was actually black that was in trouble. [31.Rd2 is apparently the only saving attempt, sacrificing the knight 31...fxe3 32.Rxd3 exd3+ 33.Kxe3 ]

31...f3+ 32.Ke1

[32...Rg8 as pointed out by virtually everybody else in the post mortem was winning for black 33.Nb6+ Kd8 34.Rd7+ Rxd7 35.cxd7 e3 this is the move that I didn't see 36.fxe3 Rg1+ 37.Kf2 Rg2+ 38.Kxf3 Rxa2 ]

Anthony returns the favour [33.Rd2 was winning for white 33...Rxd2 34.Kxd2 Bf4+ 35.Kc3 and black will be mated or will lose material]

33...Rg8 34.Rxc7+ Kb8 35.Rb7+ Kc8 36.Rc7+
Quite a few inaccuracies from both players towards the end, so the result is probably a fair outcome. 1/2-1/2
