Why were these stones removed?

Dear Go players!

Could you please tell why in a stone removal phase my upper left corner and upper right corner stones considered dead? They had a territory before:


I played as white.
Thanks a lot!

The white stones in the top two corners are dead since they cannot avoid being eventually captured. Both groups only have one eye and cannot form a second. The top-right position has what appears to be a second eye, but it is actually a false eye.



Thanks a lot!

Hello, :slight_smile:

if you are that kind of person (like me) who learns better by visuals, I tried to stitch together a sequence illustrating how both groups cannot prevent capture. https://online-go.com/review/359640

Well and if a group cannot prevent capture, it is just considered dead by default (and our score estimator) to save time of playing the whole sequence out. It may look very confusing at some cases at first, but soon it will be a second nature to you :slight_smile:

Welcome to OGS and have fun playing :slight_smile: and anything interesting you encounter, share it here. Most of us have nothing better to do with our lives than to think about board positions :smiley:


Thanks a lot, you’re so friendly! Amazing community!
Have a great evening and everything ^^
