Hmm.. difficult.
Black M4 seems to kill, and the only cases it won't will be if white can kill some black stones afterwards(probably the black corner, or s6), or do something around p8.
My initial guess was there must be something in the corner, but as I don't see a way to continue after white o1 or n1, I'm now assuming there must be something around p8, possibly in conjunction with r10 or something. But still unclear to me.

Thanks in advance to any strong players who can clear this up.

Black M4, White P2. White T6 is sente, so Black T3 is not.

You should perhaps remove the stone at Q5 from the diagram, it confused me for a second there into thinking T4 would be atari.

EDIT: Oh, and same for S14-S15. It's confusing to have stones without liberties on the board like that

Oh, right, there was p2..
Thanks for the explanation!

Fits the topic pretty well:

Lee Sedol 9p vs An Sungjoon 2p

Move 25 seems to be a genius's Tesuji.
I wonder if White r17 was a mistake, does White have a stronger resistance?
