PGB151
White's big dragon has only one eye and a possibility to get the second one on a ko. But the hot issue the fate of the tree white's marked stones and whether white can use a dead group to the left to get some advantage.
White 1 tries to pull out 3 stones and black 2 connection is natural. White 3 is a mistake. See discussion below. The purpose as it stands is to run away with the threatened stones. Black conects at the week point with 4 and white plays 5, connecting the stones and threatening black's group on the left. White remembers then that the big dragon at the top is still eyeless and jumps out with 7. This move attacks the black groups to the left and in the center. Black chooses 8 to continue the chase of the white group. White starts a counter attack on the center black shones with 9. Black 10 refuses an easy life for the white dragon.
If I have not read wrongly, I think White 3 in the original diagram is not good. It should be played at 1, aiming for a as well as the sequence from 3 to 7 (not to be played immediately) which captures the marked stones. --unkx80 HolIgor: I agree. I wanted to write about it myself. Moreover that was the initial plan. But white (that is me) got scared at this moment. White saw at this moment that black has an intermediate threat.
Things could become more complicated and white signed off. Now I think that was a mistake. Next PGB141 This is a copy of the living page "PGB151" at Sensei's Library. (C) the Authors, published under the OpenContent License V1.0. |
