Hear, hear!
No argument from me either.

This is the most unreasonable myth I have ever seen!
It is used in most human games in NZ without argument. I won't say that it
is applied correctly all the time, but I have seen games with triple ko
played out without problem.
All standard ko cases are fought the same way as they would
be fought using Universalists Ko Rules (a basic ko rule plus
no result in case of long cycles; this is like Japanese ko
rules except that they have a third ko rule for the purpose
of defining life and death around the game end).
This is confusing Robert.
The differences from the Japanese are mainly
1. eternal life and triple ko are played the same as a normal ko.
2. quadruple ko is analagous to double ko, and can really only be used as a
source of ko threats for one side or other.
3. 3 single kos cannot be used to force a draw/no result.
bent-4 and 3 points without capturing are different under AGA rules
compared with Japanese because the same rules apply after the game end as
during the game. In other words ko threats have to be considered when
deciding their status.

See above. This is bent-4-in-the-corner only around the game
end and some positions rarer by a factor of more than 1000.
There are other situations, like 2 double ko deaths occurring on the
board. However these are rare, and it is only personal preference that
decides whether it is a good thing or not.

A reasonable ko rule is a ko rule that can be stated by all
players who use it. This is not the case for the
Pass-for-ko-rule. Your reference to human players fails
gloriously:)
I wonder if any computer program has implemented this Pass-for-ko rule? :)
