Examining some other possibilities for settings, I think there are not that many that are totally comparable in strength to the default ones but this one I think is reasonably good also in the latest version of the code. There are very small differences in solving the Alekhine - Sterk position with the last versions using H50N4 settings and the 70617 version of the code. There should not really be, as Peter has said they have the same search and eval, but my guess is there might have been some small side-effect from added logging code for example, I believe Harm Geert Muller wrote somewhere that adding very innocent looking pieces of code can do something to the alignment of important datastructures for instance, so suddenly the code executes a little faster or not. I can't remember much of the details. But for instance I now get in the latest versions this result in Alekhine - Sterk:

One ply and therefore about 45 minutes later because skipping the solution at 17 ply! The rest of the output is much the same and I think the settings behave much the same, the initial other reason I liked this output much is because the settings soon, after 5 seconds, settle on the strong 1. Kf1 that Alaric likes very much, and do not waver from it in the first plies before finding the actual solution 1. Bf6.
My other candidate settings besides "H50N4" I have called "Deep II" because they use more of the possible LMR pruning and Null Move pruning. That gives horizon effects I suppose, it needs more plies to find things but I think it is
almost compensated for by additional speed. But it is very early days yet in testing this. I have not yet tested Alekhine- Sterk even but I did with the related "Deep I", only difference being that Deep I uses Lazy Eval for Nullmoves and Deep II does not.
This is the result for Alekhine - Sterk from Deep I:
Dit is Alaric 70706 "Deep"

Solved at 17 plies that is good!
I only played a few testgames yet but I think it is not much worse than the H50N4 settings, at least at this timecontrol it profits from the better speed to plydepth I suppose. In the second game against Glaurung it came
very very close to a win in a Queen ending, displaying +8.77 for seventeen moves in a row but Glaurung miraculously escaped in the end with perpetual check. Very good from Glaurung! But it escaped by a hairs width!
First two mini-matches, only four games, that I have played under the same conditions as the above matches with Alaric 70617 H50N4 and Alaric Default settings against Glaurung 2-ε/5. All games both programs using Shredder9.bkt and no booklearning, so openings are repeated with different colors in a minimatch of two games:

Draw! By 50 move- rule. But I think Alaric must have had a way to win this! I have not studied it closely...

Intermediate Result Alaric 70706 "Deep II" - Glaurung 2-epsilon/5: 3½-½
This means statistically nothing and especially not at other timecontrols I think, but it is also not a bad sign! I think the settings may be about as good as the H50N4 which I, ever so slightly, would prefer over the default settings based on the available testgames but not enough of those. I have no idea though if Peter would consider using any other settings than the defaults.
These are the internal settings:
HistoryValue 50 [default = 60]
LMRMoveNumber 4 [default = 3]
LMRreduction 200 [default = 100]
LMRStartDepth 400 [default = 300]
NullReduction 400 [default = 300]
NullStartDepth 100 [default =200]
Now I don't know what this exactly means in actual games instead of using the settings in infinite analysis, because I think the engine uses slightly different settings there, at least that is what I thought I could see transmitted to the GUI, usings Shredder's Ucidebug option, I had not reported that yet to Peter but I suppose everything is intentional. So I'm assuming these are about the settings used in actual game play as well. If not then I will just have to see what happens after a lot more games.
Peter I think there is still a slight bug in the book code!! I think I better use e-mail for that..
