seems easy
as usual the hard riddle seems like the easiest i count on you to show me the evil way i didn't think of though black b19 white basicly got 6 options e19 won't do so we are down to 5 c19 will get punished with c18 b18 is punished with b17 white c17 black c18 or white c18 black c17 down to 3 c18 is again like b18 it will be punished with c17 and white either b17 or b18 and black takes b18 or b17 down to 2 b17 punished with b18 again resulting in "if white A then black B" miai thingy with c17 and c18 lastly if white c17 miai on b17 and b18 think i got all of white's options covered
