When someone mentioned a position where a pass-alive group should be sacrificed - I wondered if it was also due to PSK issues.
I want to clarify something I said about PSK. I don't think the rule is "wrong" in any sense - after all you can make up any rules you want as long as they are internally consistent. I just believe it's a rather arbitrary rule which has been accepted primarily because it rarely turns out to make a difference in most situations. For instance, I could add a rule to chess which says "it's illegal to move a bishop to g2 on the 8th move." It would be a rather silly and arbitrary rule and wouldn't be consistent with the spirit of the game, and it would introduce a small bias against white for no good reason - but it would be a valid rule and the game could still be played reasonably. However it would be an ugly wart on the game. (Chess has a lot of funny rules in it anyway which have been added over the years to improve the game.) - Don On Mon, 2006-10-23 at 11:56 +0200, Erik van der Werf wrote: > On 10/23/06, Tom Cooper <[EMAIL PROTECTED]> wrote: > > At 01:54 23/10/2006, you wrote: > > > > >There was a posting on this list with an example of a (contrived?) > > >situation where sacrificing a pass-alive group is appropriate, in > order to > > >win a ko that is more valuable.
