Go for Beginners Erratum 1
   

Andrew Grant: The following diagram appears in the Appendix of Go for Beginners by Iwamoto.

[Diagram]
Triple ko?

It is given as an example of triple ko, with Black to play. The assumption is that Black must take one of the kos at a or b. But...


[Diagram]

In fact Black need only play here to kill with a bulky five. The kos become irrelevant. White is dead.

I only have the 1972 Ishi Press edition, can anyone confirm whether or not this error was corrected in later editions?
