Position at move 103, White to play.
Lots of thin 1 point jumps there. Seeing as neither player has presumably spotted the weakness, the naughty player in me wants to wait for black to play some endgame on right and only then cut so you get an extra wasted move as profit.

This is a variation from the 33 invasion
Black played 21 to prevent both capturing by N17 and ladder by O13
How should white respond to that?

Black played a tenuki, ignoring Whiteâs last move in the Southwest.
White to play. What can White do about Blackâs Southwest corner group?
Summary
In the game, we played the textbook sequence and Black died. But I think Black should be able to live by threatening to connect to the two black stones on the South side.

Well, sounds like a hypothetical question, so feel free to answer it.
Ok, I think white gets eaten whole. ^^
So @shinuitoâs solution looks preferable.

First problem:
Problem 223 from Cho Chikun's Encyclopedia of Life and Death 2: Intermediate
What can Black do in the southwest corner, if White tenukies after Black 16?
Second problem:
A variation on the carpenter's square
The possible cut at S7 is actually relevant to the problem!

Because of the endgame ko at B3, Black played a ko threat at K4. White got greedy and replied at P7. Instead of taking back the ko, Black decided to punish Whiteâs answer. Five moves later, White resigns.
Can you read the sequence better than a 9p?

I donât really understand w move
Résumé
W ensure some points by forcing b to capture later 3 stones, but letting black (L3+K2 or K3) change bottom in a seki looks bigger?
