Corner Tsumego

It's Monday again. Time to finish things that I left last weekend. But first, let's solve a tsumego.

Black just played at the marked stone (D2) which actually a mistake. The questions are:
1. How white can punish this?
2. What is the correct move for black?

Enjoy :)

Edit: I just found out that black can also avoid being killed in the corner. The variations in this tsumego (I believe) are very useful. Have fun in exloring them :)

First Tsumego Answer

Here is the answer for First Tsumego of the Year

Black's tenuki is correct here, because even if he played at T9, white can still live due to black's damezumari.



If black played 1 at diagram below, white will capture 3 stones and A-B will be miai for white.

Tuesday Morning Tsumego Answer

Here is the answer for Tuesday Morning tsumego .

R19 is the key point in this tsumego.



If white captures the two stones, black will play T18. White captures with T19, and then black eliminates white's second eye with T17.

White can't play T18 directly, because white will capture with T19 and make A and B as miai.

Here is a tsumego for this bright Tuesday morning. Black to move and kill. Enjoy :)

Easy Tsumego Answer

This is the answer for easy tsumego .


The throw in at is the key move here. White can't create an eye with M19 since it's a self atari. After capture at 2, A and B become miai for black and white die.
If white play O16 instead of capturing, then black will play another throw in at N19.


Black can't play 1 first in the diagram above, since white will play 2 and the throw in at A doesn't work anymore.

Black to play and kill. Enjoy :)
