As skydyr pointed out (and you learned in the game), you can't treat the N6 cut as if it were a ladder. However, if White plays 7, you can catch it in a net. After 10 below White cannot escape. Play around with this position until you are sure you understand it. Note that the dead White stones have considerable aji. You cannot resist either the cut at 'a' nor the push at 'b'. Indeed you probably have to give up the stones on the right side if White keeps pushing after 'b'. Note also that if White had used 7 to play atari at 'c', Black would have had to let the stones escape due to the aji on the side.

So is 2 above the right way to answer 1? No it is not. You could do much better. You should notice that the lower right White stones are not alive. Your goal is not to catch the N6 stones but rather the lower right group. Start from the other side with 2 below. If White pulls out the N6 stone almost any play on the right protects everything and ensures that the lower right stones are captured (playing at 3 is the most conservative). If White plays 3, trying to use the aji of 1 in order to live, it looks like Black can keep everything with 6 and so on. Note that if you play 2 at 3 immediately to keep the right safe, White can capture two stones with 'a'. This is not terrible compared to your gain on the right. However, you have time to protect with 2 if you understand conditions on the right.

Thank you so much for your suggestions! :)

I do now understand the net but I will probably not see this in games. How can I practice this?

The same thing on the right, I would never see this in games either. I still have this beginner problem: If my opponent attaches my stones my mind goes crazy like "omg, what shall I do, I gonna lose 2 stones". I should relax more during games to see the right moves/answers but it's hard.


Except playing games, I did start Kageyamas "Lessons in the Fundamentals of Go".

And here is my latest loss:



1. What is the best answer after white O3?
2. Instead of M15 I should have played something like R14?
3. The upper right is again a debacle, like skydyr said. This happens often in games, don't know why I even do win some of these and how to stop making crucial mistakes.
4. What is the best answer to white K3? I wanted to prevent him accessing the middle so that I can get some territory there but it was a complete fail as you can see.
5. I should have taken F17 so I can get his upper left group or the stones in the right of this group.

This is my worst loss so far:



My opponent was only fighting and took about 0,5s per move. This was infecting my play style, I couldn't resist to do the same. The result is speaking for itself.

Is he sandbagging or cheating?

The good thing is you already correctly identified one big problem.
