As Black move a3 comes to my mind in micro-seconds, I guess it's not the right move... hmmmm. By the way, is it Black turn or White turn?

I think I've found a possible solution whoever has to move: 1) If it's Black's turn, a3 and I haven't found a plausible way to save the b3-c3 group; 2) If it's White's turn, a2 and the b2-c2 group falls also, because b1 doesn't work (hoping for a1 and Black plays a3 gaining a1-a2) if White plays a3, and the b2-c2-b1 group is gone. Since my level is really low, I could have made several blunders... :)

Hi, ok, some hint: black lives without ko :-). A3 doesn't work: Black A3;C1; black needs B1 otherwise dies big; A2 is now tesuji and W has to D1; A4; B needs to disconnect white at A5; White E1 and this is ko :-). Enjoy more!

This problem took my 6d friend 1 minute to solve, my 2k friend more than hour. Once you see the move, it is simple.

Looks like black has to begin with the empty triangle, then the liberty race is ok and white can't set a dead shape.

Yeah that works. b1 or b4 both work for b to play and live.
