It is great to see Marco back, as he was having some difficulties in his private live. But now he has resolved his issues.

Hi, thanks for posting!

SugaR XPrO 1.0 32-64
Introduce my changes "Draft at Komodo-style contempt": value our pieces, our pawns and
our mobility a little bit more than the opponent's.

But why evaluate "winning and loosing optimism" differently too, if you can put in positive and negative values anyhow


And then, if that maybe seen a little complicated only, why then not at least something like King's Safety to be changed too?
If I could have further wishes even, I'd like to have an option for changing nullmove- usage or verification too,
It's rather long ago since we had a SF- derivative with UCI- parameters for both, Evals and Search,

[peter]

But why evaluate "winning and loosing optimism" differently too

Think I simply had not got it till now. It's the chance to change Eval- parameters in case of winning positions differently from losing ones, so to say relatively to the advantage or disadvantage of one side, attacking or defending cases.
That could be a clever trick indeed, let's see...

[peter]

And now Marco even has added 4 more UCI- values to adapt nullmove- pruning and -verification, thanks a lot for this too!

But these values (UCI C1, C2, C3 and D1) together with the new Eval- parameters won't be easy to be tested, will they?

That's the code- sniplet old and new (for nullmove- verification adaptable):

&& (ss->staticEval >= beta - 35 * (depth / ONE_PLY - 6) || depth >= 13 * ONE_PLY)

Patch

if( (((depth-R) >= ONE_PLY) && ss->staticEval >= beta - C1 *(depth/ONE_PLY - D1)) || (ss->staticEval >= beta + C2 + C3*depth/ONE_PLY) || (depth >= 13 * ONE_PLY))
