It is OUR premise that if a VARIANT of a game has ALL and ONLY all of those conditions, then it is an invalid variant because it hurts the mainstream game in the LONG-run.
Ok, well it’s MY premise that one game is a variant of another if it’s rules can be explained more easily by describing the differences between it and the main game, than explaining explaining the rules of that game would be. For example, I can say that fun-pente (as I have called it in previous posts) is ‘official’ pente without the move restriction. I can say that much more easily than I can lay out all the rules for fun-pente. As far as I’m concerned, it’s a variant. Keyro13 is Keyro Pente played on a 13x13 board. That’s much easier to say than to state all the rules for Keyro13 directly. It’s a variant.
Now, with my premise, there is no issue of games being valid or not. I mean, one could play just about anything they want. Pente-on-a-5x5 board? Go ahead. I’m not gonna play, but if you want to, be my guest! Pente-where-more-than-five-in-a-row-doesn’t-win, pente-with-unlimited-captures, pente-where-you-can’t-win-diagonally? All good! Have a blast. How about this one, checkers with shot glasses, when you make a jump, drink your opponent’s shot, when you make a king, add an olive (yes, I stole that from M*A*S*H). I LIKE that variant!! My point here is that I can make up any game I want and no one can tell me it is or isn’t a valid game.
Furthermore, my premise doesn’t take into account anything about the original game. AND IT SHOULDN’T! Whether or not a variant has some kind of impact on the game it was derived from doesn’t validate or invalidate the variant!
Also you said:
Any other variant that doesn't negatively impact the ability of one side or the other to win in Pente or Keryo Pente is OK.
Ok by whom? You? Me? Us? Them? God?
Why can’t a variant ‘negatively impact the ability of one side or the other to win’? And if it can’t how can you allow both Pente and Keyro Pente. Surely in one variation, player 1 has a bigger advantage than in the other and therefore must go. Or are you saying that we can create variations of pente so long as player 1’s advantage is no greater than it is with the current ‘official’ rules? Well, who said the current amount of advantage is the correct amount not to be exceeded anyway?
