xela: If black plays at B1 first, then after W2, white wins the race.

joelr: Shouldn't W4 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.

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.
