You may be incorrect. I did a bit of playing around with 5-man DBs, making
moves, and the following line MIGHT win for White:

1.Nc5 Na3+ (forced -- 1...Kxb6 results in Mate in 34)
2.Kb3 (or Kb2) Nc5 (forced to keep the draw chance)
3.Na4

Resulting in this position:

[D]2B5/2k5/1N6/1n6/N7/1K6/8/8 b - - 0 3

Of course, my chess vision just might be terrible, and I can't see the obvious
draw here for Black. Anybody feel like building the 6-man DB required for this?
I don't have the CPU time to burn right now. I could do it after we ship CM9000,
in about 10 days....
