Go:
This is the program Valkyria written by Magnus Persson.

As long as the game is exiciting I let the program search for 12 hours or even more using 2 threads on a fast CPU. A special version of Valkyria developed for deep searches is used for this.

I do this to develop an opening library for Komi 5.5 on 9x9. And of course to win as many games as possible!

If Valkyria is clearly winning I let it spend 2-10 minutes per move. If the game is over I will take over and just use Valkyria to check if the simplest move to play also wins.

The program will resign if you get a clear won position.

Moves are manually entered so feel free to ask questions.
