[Diagram]
Diag.: Position after black 181

White is in a big trouble. The group at the left side is dead, two groups at the bottom are separated. The game seems lost and white takes extraordinary measures. During these 10 moves white manages to get at least some compensation for losses. Let us see if black surrended to the presure.


[Diagram]
Diag.: Moves 182-191

White 5 takes ko. Black 8 takes ko.



White 1 tries to complicate things. White puts one of black stones under atari.

Black 2 takes white stone. Black cannot allow white to capture the marked stone because his own group will become too weak. Black can play at 6 or take a ko. In this situation is it always wise to take the ko once, make your opponent to spend a ko-threat and then connect at 6.

White 3 is a natural ko threat that black cannot ignore.

Black 4 connect, otherwise white would capture and will be past any problem.

White 5 takes the ko.

Black 6 connects. The value of this connection is too big and it is quite probable that white would ignore many ko-threats for it.

White 7 is wrong. The idea is to kill the black group anyway. But actually this move does not work.

Black 8 takes the ko.

White 9 is threatening the group at the top. Is this a correct ko threat? I don't know at this point.

Black 10 gives in to the presure. He throws away a group at the top to take what seems to be his anyway. Thus white got some compensation for the lost stones and the only worry remains a group at he bottom. However, at this point balck is still ahead.
