if You want something really weak, You may compile this thing:
https://github.com/nescitus/mygobot

It is based on Brown and uses pure Monte Carlo (no tree search) +
excludes some patterns. To run it, You would have to set number of
playouts in get_ai_move() and disable debug information, setting
useDebug to DEBUG_NONE.
