Hi, ihave a problem understanding this puzzle can anyone help?
the solution is supposed to be Ko
where is my fault on this sequence ( sorry if i am using wrong notation , i am just a chessplayer)
1.S19 S18
2. T18 and this is supposed to be Ko. Lets say Black plays something irrelevant.Then white can continue wtih 3 T19 and if black plays R19 white goes T19 and black cannot make two eyes and his group is therefore dead , what am i doing wrong?
