This is Iwamoto giving Francis Roads seven stones back in 1975. Black lost a big group at top left but nearly made up for it at the bottom. Here is the final nail in the coffin: Black to play and do something about the marked white group. (The S1-R2 exchange didn't actually happen in the game; I've added those stones to reduce distractions.) |

Black wins the ko but loses the game decisively: white has multiple large ko threats to break into the bottom left area. kvasir wrote: I think it is like this... Yes, that's the best move :-) |
