Problem
White to play in this position where Black has numerical superiority.
Clearly we're looking at a way to capture the marked cutting stone or otherwise make shape by using that potential.
A is an obvious ladder breaker but likely not the tesuji we're looking for. Also, Black can probably safely ignore

Tesuji
Marvelous move!
is at A so that Black has to either allow a ponnuki at B or a capture at C

Alternative
The difference with my choice is that
is much more devastating if Black
reinforces at
.
KataGo comes up with this sequence. The idea is similar: if
continues the ladder, White will cut off
&
.
Next
continues at A.
KataGo needs to be fed the tesuji in order to appreciate it at fewer playouts. It then offers
as a resistance. White now continues with
or A. This situation requires many more playouts.
