How can I prevent white from making a living?

here, bottom right white stones made a living in a game I was playing and I couldn’t stop it,

and I wonder, was there a way I could prevent that? how?
thanks for the anwers.

You can make a ko by playing the G2 atari. White cant connect, so they would play F2, black would capture on H3 and then white would need to find a ko threat somewhere ^^

So yeah, locally you can make a ‘ko to kill’ with that shape, and based on how the rest of the board looks like you should probably be able to win the ko too.

Next question, white’s last move was a mistake. What better move would have let white live unconditionally, no ko?

Spoiler for a solution

F2, if black play J4 white can just connect H3

Please use spoiler or hidden tags. You’re not alone.

if black played at F2, white could make a living

why should I use spoiler?

To let other search.

i really don’t know what do you mean

An attempt a trying to solve it is … kind of disrupted when one has already read the solution.

since you posed the question, you don’t need to use hidden text. groin was requesting that people giving you answers hide those answers so that people that come along later have a chance to solve the problem themselves before seeing what others answered.

And this thread yet again shows why should be able to quote the post you are replying to, even if it was the last one. (Counting_Zenist was replying to my “how to live instead?” question, not OPs, Groin was replying to Counting_Zenist, not OP).

Yeah, it’s probably the one aspect of Discourse I think is not great. Overall it’s still my favorite forum software to use, though. Most of my complaints with Discord boil down to, it’s not Discourse
