http://twixt.wetpaint.com/And this guy, Alan Hensel, has some tools and pages that TwixT experts refer to:
http://www.littlegolem.net/jsp/info/player.jsp?plid=2674I believe he is the person credited with the TwixT Commentator site/tool that is linked to from the Little Golem games. They're not affiliated but complement each other.
http://twixt-commentator.dyndns.org/It's very educational to sift through past games where folks have talked about the game afterwards. They're usually the most competitive of the LG games and played by those in the top tier, so you wind up learning a ton once you get used to the jargon. I still have a hard time digesting game analysis by reference to the grid index. I'm a more visual person, so to me it's genius how you can post hypothetical moves and actually see it projected up on the game board.
I think that's all I know about. LIke I said, the Wikipedia page for TwixT is pretty detailed. In fact, I think Alan Hensel may have edited much of that. He seems to be the acknowledged expert.
