T1j Twixt engine by Johannes Schwagereit

    For those who want to play a computer opponent not as strong as TwixtBot, you could always download T1j. It doesn’t do link removal correctly, but it does offer the pie rule which is much more important, and better still, it offers row handicapping. So if it is stronger than you you could take a handicap, or if you are stronger you could give one.

    This has been available for a long time. It might require an older version of Oracle Java such as 10.0.2

    Here is a link to Java 10.0.2 Don’t install it, just extract it to a subfolder and use its full path when invoking it.

    This IS nice of you to post for people, David.  I’ve had T1j for years, but rarely ever play it.  Compared to the old, WEAK, Twixtbot (which is worth around 1600 strength), I would give T1j only a rating of around 1200; again, that is in MY estimate.  It IS still worth having, and I’ll admit that I have NEVER fooled around with the row handicapping feature – and perhaps I COULD arrange more of a challenge this way.

    There is an Android phone app (free download at Google Play) which plays Twixt, and the creator states that he is using the same algorithm as T1j, meaning it is not very good.  However, it DOES play the game, and can even WIN – if you are not careful.  Again, FOR FREE, what the heck – may as well download and install.

    I still want the ol' weak Twixtbot back!

    If someone wants the source code to the old twixt bot and wants to polish it up, I can send it to you.  The new one too.  You can drop it down to ~250 trials and it makes a tough interactive opponent.

    I would love to learn Twixt strategy from playing strong Twixtbot (on a PC, because the LG bot, while appreciated, is slow).  I just don’t have time to struggle with source code, although I thank you for making it available on your github.  But wanted to note two design goals for anyone interested in improving user experience: 

    1) aside from the obvious goal of a standalone .exe with gui, can it be integrated with jtwixt or any other Twixt game viewer?   https://canyon23.net/jgame/README_twixt.html

     2) Can the AI provide win% feedback to the player (or any other useful data from the neural net) to facilitate human learning?

    1) almost certainly

    2) yes, it has a nice win % number.
