Intro

Dear Visitor,

This site isn't officially live yet. However, I have released a beta version of Tom Thumb for friends to give it a try.

Tom Thumb is a chess program written in the Scala programming language.

Installling Tom Thumb on Windows 7/8/10

Installling Tom Thumb on Ubuntu 16.04


Installling Tom Thumb on Ubuntu 18.04

Same procedure as Ubuntu 16.04 but if you run into font problems (menu is messed up) please update the freetype library:

sudo add-apt-repository "deb http://us.archive.ubuntu.com/ubuntu/ artful-updates main"
sudo apt-get update
sudo apt-get install libfreetype6=2.8-0.2ubuntu2.1
sudo apt-mark hold libfreetype6

To run Tom Thumb as UCI engine simply add 'uci' to the command line

Example commands when in engine mode ('d' and 'perft' are actually not UCI but where added for testing purposes):

Disclaimer

Although you really can play chess against Tom Thumb and it ships with a working database, the program is by no means finished and still has bugs and some major features are missing.

Tom Thumb has been tested on OS X 10.x, Windows 10 Home en Ubuntu 16.04 met Java 1.8.0_121-b13.

have fun!

PS care for a puzzle? select the right version given an alpha beta treestructuur.

Circles are 'maximizers' and always choose the highest value, squares are 'minimizers' and choose the lowest value (they counter the decisions made by circles).
