Subject: Re: The B+N Database Setups
I do not know what the exact position is as of yet, but when I do, yes, I will play the losing side of sole king, and everyone else will play the strong side with B+N. We may switch sides if they want a demonstration of the winning technique. I am still a ways from this. I just ran a test last night on the code to make sure everything is in place.

In the 37,957,920 positions in the database, only 9,489,480 are unique, the others are reflections and rotations. I ran the test over all of them just to make sure.

It found 532 checkmates and 17,576 stalemates. These results are both encouraging since they are a multiple of 4, and the board will produce 4 mirrors of every pawnless endgame in Gothic Chess.

I can reduce the size of the database by 400% when I get a more sophisticated lookup scheme, but for now, I just want to compute the data.

It took 15 seconds to do this first pass, which is the quickest pass. Each subsequent pass will take about 1 minute with database lookups and move generation. So, once everything is in place, it will only take about an hour to solve the database.

Then I have to write the code to look it up and translate the best move to a move on the board.
