FruitFly has problems with these positions.
Score : +0.45
Depth : 9/33
Time : 00:00:02

N/sec : 180952
1. Nf6 Bxf6 2. exf6 Nxf6 3. Nxf7 Kxf7 4. hxg6 Ke8 5. Qxb4 Rb8
They are too easy!
I'll give it a bit more time to think.

It is possible that g4 is an alternative solution.

Re: test position, Serban-Schuster, World Corr Ch 26 2010
Black must have blundered somewhere in the opening, I have not checked it yet but that must be unusual at the level of the World Championship final!
This is Rainbow Serpent's take on the position. After Stockfish synchronized the way it codes castling rights to be identical with the way PolyGlot does castling rights, I had some trouble following that, because I had not copied all Marco's changes. So I synchronized Rainbow Serpent again with Stockfish, it now has almost all the changes after where I stopped synchronizing with most of the code in the master, the Reduce Stack Usage commit of April 8. Marco changed a lot after that and some before but if it did not change functionally I did not always follow the master source. But now we're up to date again
Maybe not very original but at least it does make comparing and maintenance of the remaining changes easier.
I have not tested this new version a lot though, currently the 'space' routine in eval is being "upgraded"
I am not satisfied with it yet but what I had in its place was also not working. That may be the fault of search more specifically the "Sharpening of PV tips" code, what I now think of calling "PV Leaf(-shaped) search" instead. So I think I will look at that first now. This is still an opening position so "space" is still evaluated just as in Stockfish, with all the minors still on the board so thanks for this testposition Jon!

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.
