Toshiro Kageyama in his book "Lessons in the Fundamentals of Go" presents us with some life-and-death problems. Here is one of them with mine and Kageyama's solutions. Does mine work?

Thanks.

White has a stronger move for 4, so your attempt fails.

Here's how it plays out in full. B can slice off a few stones but W lives.

Txewì, you're wrong.

In your second sequence w6 lives, but loses points compared to p8.
And your claim that w is alive after the third sequence is plain wrong.

I think Suprun's b1 ends in ko.

@Txewì: In you first sequence :b5: is gote (white can live without answering). Locally White connects with :w6: to save 3 stones but it is not needed.

don't be so hard on Txewì... the whole point is that SuprunP's "solution" doesn't work (for various reasons).
