I know you all love to work your go, so here is a small tesuji problem I have just seen tonight played at the USGO Cotsen Open between two high dan – pro level players.

It is black to play and his situation seems quite bad with two stones nearly dead at D14 and D15, but… he had a tesuji in mind before he launched the whole sequence that white totally overlooked. Can you see it ?
