Not sure this question is in the right place, but I was just wondering if my solution to this problem is ok, or what I’m missing: https://online-go.com/demo/167534.
It comes from an app called ‘Tsumego Pro’.I Indicated my solution in the top variation, then the one Tsumego Pro says is correct.
Am I missing a ko, seki, or something else even more obvious? Just thought it would be interesting (or possibly embarrassing…) to get a comment on it if anyone has the time. It’s considered “hard” in the app, so kyu players beware! (I’m a 10k, no offense intended.)
