xela: If black plays at first, then after , white wins the race.
joelr: Shouldn't be at a, else Black gets out to b? And what about
To me, this solution seems incomplete. Black moving to 3 is a mistake; White can make an eye forcing Black into an unfavourable situation. A KO can develop. We shall assume that KO for Black is bad.
Liberty fight looks bad for Black now. (I couldn't find another way for Black to fight and gain liberties)
This order of moves is better for Black
This fight seems a lot harder for White to win.
tapir: Black is dead after the last white move (I added it). White just has to give him the three stones on the left.
