Below is what changed.
The next two months will see many new knowledge tidbits added to
the position evaluator.
My original plan was to create a simple position evaluator and leave it
as is for many versions. During those stages work only on the search
algorithms. This made it easy to tell why moves were made (search or PE).
Now I am quite happy with the search speed, thus most efforts will be in
the PE. My findings are that big improvements come from PE work. Huge
speedups are necessary for improvement while keeping the PE weak.
A breif synopsis of what changed from NoonianChess 3.0 to 3.2.06
-st command to set fixed per move search time
Test Suite Capability (ts)
Three fold rep pos fix
EP moves working
Refinements in extension usage
Added support for X Moves in Y minutes time controls
some algorithmic speedups
move ordering improvements
Position Evaluation Knowledge
block 2nd rank center pawn
King Tropism
Kingsaftey of adj open files
Backward Pawns Penalty
Backwards Pawn Rook attack
Isolated Pawn Rook attack
Bishop blocking passed pawn
knight blocking passed pawn
knight traps
Uprotected piece penalty
rook truly behind passed pawns

Hello Charles,
Is there any chance that you can offer this new version in a package that will function on a Celeron 433?

The Pentium version should work for you.
