GN[Rated game]PW[yangjt]PB[byun9947]WR[7d]BR[7d]DT[2011-03-06]SO[www.cyberoro.com]US[www.cyberoro.com]C[This game happened on 2011-03-06, between two 7d players, on the WBaduk server. It is an exciting fighting game! White forced a weak group on Black, and kept harassing it skillfully during most of the game. When the moment came to kill the beast though, Black fought back inventively, and the game reached a climax with two dragons fighting to death.

(;B[go]LB[cr:A]C[Black diverges from the joseki, trying to separate white stones rather than forming a base in the corner. Black's group will end in bad shape, but as Alexandre pointed out, this is the Korean style of playing: "Cut first -think later".]

;W[ir]C[The sequence up to White 34 looks good for White: now Black has a weak group which can be harassed, while all White groups are more or less solid. The lower-left corner may not be secure yet, but as the group is open to the center, White has nothing to fear for now.]

;W[gj]C[White 66 looks like a tesuji to stop Black from escaping, but White's shape is a bit too thin there, and Black manages to find his way out.]

;W[le]C[White 78 is a nice flexible move. Now, White can either invade the top, or lean on it to continue the attack on the Black dragon.]
;B[nf]C[Black takes up the challenge with 79: the White group on the right looks a bit weak, so Black can fight on equal terms there.]

;B[ic]C[Black manages to live with 121, but now White is strong in the center and has sente.]
;W[ok]C[White 122 is a nice move. By threatening the dragon, White can easily make shape for his group on the right and build more thickness to try and kill the dragon.]

;B[fe]C[Black 145 came after many minutes during the live. Unfortunately, I am not strong enough to tell what the correct answer to this move should be.]

;W[df]C[White 180 shows White's anger. He had the initiative during the whole game, and having to fight a ko to kill an already-dead dragon must feel terrible. There must have been a mistake with the way White dealt with Black's ultimate attempt! A semeai appears.]
