I'll check the Obsidian every few hours or so to catch its evaluation. If the number goes below -5, then I'll resign the game for the machine.

TC plays c1Q with a score of 4.4

I've assumed that the Obsidian will play BxQ and started it thinking again anyway.....

After 2.5 hours, the Obsidian says: ply 11 (-5.62) 47 Bxc1

So, from what I promised earlier: White Resigns

Thank you as well.

I may have mis-typed the ply number; the ply may have been 13 instead of 11.

I probably should have let the search conclude on its own to see if the machine would resign by itself.
