Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

Re: Find: Nd5!!
But a tweaked version of Rainbow Serpent with slightly adapted new passed pawn code for the position is faster. The "new" passed pawn code - it's only borrowed from Ancalagon - really slows the engine down, that is too bad, maybe it's a bit less for a 64-bit version. If you want more knowledge you haver to use more bitboards. I don't really see a way out from under that. The only thing I can think of right now is not to use full eval in quiescence search. But I am sure that has been tried a 1000 times before. I have not much confidence in that idea.

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

Re: Find: Nd5!!
ChessMind doesn't find it in three minutes...
It is wasting too much time on both Bxb5 and Nxb5, not being able to go deep enough to see Nd5.

If so, Good name choice and interesting analysis lines from the engine.
