Diabolical on TsumeGo Hero

David Mitchell has worked with TsumeGo Hero over the past month and we are pleased to announce there is now a collection of 10 “Diabolical” problems on the site.

TsumeGo Hero is a great platform for studying and practicing life and death skills.  The “Diabolical” problems are not easy. Each problem consists of four or more positions on the board. Just one is unsettled; killing a dead group or living with a live group is a waste of a move and clearly wrong.
