- ah...i think we have a problem in semantics...i agree that its trivial,
- always should end in a draw and is arbitrary in size. those are not what i
- would term "defects" in the rules. so i guess its how we use the term,
- "defect". in my application here, i was referring to the system of rules
- and how internally consistent they are. i've often said that rules to a
- game is like trying to cover an open set with a finite number of closed
- sets. in this case, the fact that tic-tac-toe is trivial and completely
- treed out has nothing to do with my "defects". going back to Go, the
- ko rule immensely augments the game, so its by far preferrable to not
- having that rule (then lots of go-games are alas trivial). the jump from
- 3x3 to 19x19 for Go-Moku gets rid of a lot of the triviality of tic-tac-toe,
- and the double-3 rule is a small price to pay.
-
- and looking up at what i said above, i said a "game without defects", so i
- guess i wasnt describing what i was saying....:-) i was trying to stay
- within the system of rules. so going back to my topology analogy, in
- the case of tic-tac-toe, while the rules have a minimal finite number of
- closed sets or perhaps a sort mutual orthogonality, the open set that they
- cover is a trivial open set. maybe its that orthogonality - the double-3
- rule isnt "orthogonal" enough to the rest of the rules...:-)
