An Annotated Game from the 9th World Xiangqi Championships

I want to test if Java chessboard can be used on blog page. The game posted here was played between Liu DianZhong, GM of China and Nguyen Vu Quan of Vietnam in round 6 of the recent World Championships in Paris. Thanks to IGM Zhao GuoRong for annotating the game.

In the commentary, the move number is tagged with r or b to differentiate the colour. So 11r means Red's 11th move, and 11b means Black's 11th move. The number within the blackets is the move number shown on the Java chessboard which counts the moves singly.

Among the opening systems for Red, the 5-9 Cannons is much favoured by players of aggressive style. It offers more variations with plenty of attacking opportunities for both sides. Having done some careful study before the match, GM Liu decided to play this opening. His intention is to seek better results by engaging the opponent in fierce contest.

11r(21) Red has several options: R8+6, C9+4, C5+4 are also playable.

11b(22) Another line of play is c2-1; R4-3, e3+5; R8+7, h8+7; R4-2, c7+1.

13b(26) An alternative is p7+1, then E1+3, c7=3; P5+1, p5+1; H7+5, r8+3; H5+6, r8=4; H6+7, r4+3; an equal position more or less.

14r(27) The usual continuation here is H3+4. "Seeing that my opponent moved pretty fast in the opening stage, and thinking that he might have done some homework about the usual line of play, I decided to make a detour and surprise my opponent with this unfamiliar move." explained GM Liu after the match.

14b(28) Certainly not h3+1 which leaves Red with Pawn majority after C5+4, e3+5; C5=9.

18b(36) Guarding the Pawn rank. Good move!

20b(40) r1=5 would be a blunder. C5=2, r8+4; H3+4 and good-bye to the black Chariot.

21r(41) Simple and effective. If H5+4, r8+2; R8=4, c3=5; -R=5, c5=2; Red would not be able to dominate the game easily.

22b(44) This costs Black the game. The right move is p7+1, with two possible lines of play as follows:

(a) H4+6, r1=4; H6+8, h8+6; H8+7, k5=4; Red has nothing to further his attack
and Black has a better chance with the ensuing h6+4 or h6+5.
(b) E1+3, h8+6;
R4-4, r1=3; R8=4, e7+9; and black has a slight edge.

23r(45) Winning a piece for nothing. However, capturing the Horse with the Cannon would allow Black to gain back a piece after p7+1, E3+1, r8+1 and in all likelihood draw the game.

23b(46) p7+1 will not save the day either. R8=4, r1=5; H2+4, p7+1; -R-1, p7+1; -R+1, r5+1; H4+3 and Red wins.

26b(52) Tougher would be r8=1, C9=8, r1=3, though being one piece down.

In the final position, Black resigns as he is helpless against the ensuing C9-4 or R8=4.
