Endgame Test Two - Black Solution 1
Difficulty: Advanced
Keywords: EndGame
Black 1 is a nice tesuji. After White 6, Black 7 seems to be the largest move, but...
...after that, White 1 and 3 are sente. After White 5, White is going to win by about one point. --TuRen? JanDeWit asks: In diagram 1, why doesn't White play her second move at Black 5? The way I see it, Black is going to have a hard time making life!
Black could just play atari with 3. If White connects at a, Black captures at b (atari) or vice-versa. In any case, White's group has been 'punctured' by Black 1 and White will have to pull way back, e.g. to the circled point to defend. White may be better off answering Black 3 with d (Black captures at a) and b (Black connects at 2 - he could play a ko), then play e in sente (Black connects at f) and connect at the circled point in gote. By the way - notice that if, after Black 1, White plays at a he is caught in damezumari by Black b. Black could (if I have read correctly) also play 1 at d, but would end in gote (as opposed to the right answer). --MortenPahle (10 kyu) Thanks for the explanation! I'm only just beginning to get a grasp of situations like this around the edge (am I running short of liberties? who has sente/gote?) and this a typical situation I'll have to learn to avoid/read correctly. -- JanDeWit
Black 1 is good move because...
Black can reduce White on the right in sente.
Black can then win by 1 point if he wins this ko. But...
Instead, White should play like this. The result is a tie. --Eyesore (8kyu) This is a copy of the living page "Endgame Test Two - Black Solution 1" at Sensei's Library. (C) the Authors, published under the OpenContent License V1.0. |
