In the following game Rebel 15 will claim to have full positional compensation FOR A ROOK. This is probably just not really possible in the game of chess IMHO. I could look at this one with Stockfish, but I don’t want to. It takes me back to 2004/2005 where Junior was the hot shit, but it tended to take things too far. Re8 looks weak already, a5 takes things too far. This is the way Junior used to play, Crafty has always scored way better than should be expected against it. A strange game.

If you want to attack you need more then an open file and queen and rook. You must bring the other pieces to the king too. Maybe cstal would have won this position against crafty.

Looked at the game. Unreal of course. But I do have an idea why it played like that. I hope it will be fixed in Rebel 16, definitely not in planned updates for Rebel 15.

Down an exchange, Toga IV 1.1 goes for Nb4 at move 15 also, with approximately a similar evaluation until depth 18 when it switches to Rc8. With multi-PV, the second choice remains 15...Nb4, the eval is +1.30 for white at depth 21; at depth 23 (now), first choice, evaluation +1.01 white.
Marvin with the first Rebel NN also choses 15...Nb4 until depth 20, before swithing to 15...Rc8 at depth 21. (Nb4 again at depth 23...)
I will check now 13...a5, but it seems it is a problem from previous versions.

That's where the trouble starts. A very bad move.

Both Toga IV 1.1 and Marvin-Rebel analyze 10...Qa5 and 10...h6. Marvin also sees 10...e5 as a good move here. Will let the engines analyze a bit longer to see if 10...a5 somehow pops up.

That's a pretty well-known position. The trouble probably +starts+ with 9....Re8 ( where 9...Qa5 is one of the current mainlines of the Queens Gambit), but this is deep stuff. ...Re8 has been played by strong players before.
But you are absolutely correct, that 10.. a5 is just a blunder where 10...e5 isn't really great but playable.

Shredder's last references in the online book are 10...Qa5 (1981) and 10...e5 (1986). So the position is not really very popular with GMs it seems? I have no idea.
Rebel 14.1 MOD prefers after a while 10...h6, then goes back to 10...Qa5. I tried to put in some code a while back, this is not in the published version, for detecting Bishops of unequal color but I don't think I got it to work, it does have an influence on the eval that I can't really track yet. Fruit can detect the colors of the squares Bishops are on, so Rebel Fruit based should be able also I thought, but I think I botched that code.
Code:
r1bqr1k1/pp3ppp/2n1pn2/2bp4/2P2B2/P1N1PN2/1PQ2PPP/2KR1B1R b - -
Engine: Rebel 14.1 MOD (512 MB) gemaakt door Fabien Letouzey, Pawel Koziol, Chris Whittington and Ed Schroder
I have not checked the plain Rebel 14.1 but it is not impossible it is a Toga problem also. But I have not checked at all, maybe that is not true.
Ed, I would like to try to build Rebel 15 some day from the sources, but it is not possible yet. Because there is no NNUE in the code... I think it is kind of against the GPL not to have code downloadable somewhere that you need for building the stuff ... I was going to wait a bit but before you know it people will send lawyers.... No hurry for my part. Can wait a few weeks. I dont think I can build Toga yet with Microsoft Visual C, at least only a very slow version. Fruit works much better, for some reason.

It's really up to the user which compiler he wants to use. Fruit / Toga are GCC based, small miracle it works with Visual Studio.

Sorry Ed, I see where I went wrong, the net is in a big .txt file that I looked past. Sorry! Should have checked the size of the file better which is about the same as Toga 4.11. Will try to compile it.

If you can get it to compile and run in VS2022 debug mode, that would be a great leap for mankind and please send me a source copy.

I have created a double sized net, the executable goes from 24Mb to 46Mb, so it can hold more chess knowledge. I tried if it would fix the 10..a5 bad move and it did.
Code:
FEN: r1bqr1k1/pp3ppp/2n1pn2/2bp4/2P2B2/P1N1PN2/1PQ2PPP/2KR1B1R b - - 2 10
It's currently not as strong as Rebel 15 because each doubling of the net size causes a considerable drop in NPS. Whether the double sized net has a future of best net has to be seen, but it can be useful as analysis engine. Time will tell.

A non-avx2 compile would be most than welcome. Since I am one of the few using Rebel as his main engine for analysis. (Would I be surprised if I were the only one?)

Hi Chris, I'm not sure I can contribute much. I'll describe what I did. I can make a compile with Visual Studio 2022, but the error I see is still the same as the one I described in the programmers forum here with Toga 4.1.1; the first Rebel Toga. In the Command Line Interface everything is, as far as I can see, the same as Rebel 15, the speed just a little bit less only. "uci" command gives correct output, go depth 20 in the start position is identical. I did not start a whole new project, I took the solution from Ed for Rebel Fruit again and transplanted all the files until everything matched Rebel 15. The .sln was retargeted to the new compiler. So there may now be small changes with a whole new project. But at least it compiled, I do not know how good Rebel 15 compiles with trying the wizard etc.
So in the CLI everything matches, as far as I can see, this is another testpos, regular, official. Rebel 15:

When I try the position just before this, before Stockfish's mistake 52. g3, in the Shredder GUI with the full game, you can see the error:

It is a bit random at which depth the Fail Low occurs with what is already in the hash table. So that might be a clue, if I start searching first a move at the start of the game and then go to move 52, the Fail Low will be at another depth, say depth 34 or something but otherwise it is the same, all zeroes to depth 63.
Rebel 15 does not do this, at least I have not yet seen it do that. Because it seems some iteraction with the hash table, or some "immediate draw" triggered in Toga, I'm not sure any asserts will be triggered in the Toga code right now. But I can make a debug compile.

Use these exact settings in the configuration manager -> Optimization and your problems are over.

Thanks Ed again for that, I think it works! (It must have worked with the first Toga Rebel too but I did nor remember it perhaps. Strange I'm not sure anymore....) Thanks Ed and Chris for Rebel 15! Somehow the other settings for the compiler optimizations I can't find at the moment but they have to be somewhere because I have seen them before... Now I only see the 'Whole Program Optimization' and that I have switched off now:

You are correct, I posted the picture before. There is something fishy in Toga (or the compiler) because Fruit and Growing Fruit don't have this problem, both worked fine with the natural 'Whole Program Optimization' set to on. You can try the original Toga in GCC with 'Whole Program Optimization', it compiles and plays fine, not so with VS.

I am very sorry to say Boban but Chris and I have given up on a SSE version, it doesn't compile without errors. It's either a bug in the compiler or something weird in Toga, we both assume the latter for instance because Growing Fruit did not have this problem. A second indication is quite technical but I like to mention it anyway, the problem Eelco had.
It's extremely odd Whole Program Optimization has to be set to NO else Rebel doesn't function properly resulting in a lower NPS, this also counts for the AVX2 version. Again, no problem with Growing Fruit.

Thanks, Ed. You tried, it did not work, you did what you can. Bugs would also explain the problems with the search, where Toga misses mates.

Sounds like you’re trying to compile with debug mode ON at the same time as whole program optimisation ON. They are mutually incompatible, IIRC.
Other possibility is there’s a linker option set, which then clashes with WPO. Possibly the result of carrying over a dot.project file from another project. In the end it’s just a case of getting the project and options set correct, then everything works.

When I look at Growing Fruit's repository, in pawn.h and pawn.cpp already Growing Fruit uses several bit functions, BitFirst, BitLast etc but also BitCount. Not sure about Fabien's Fruit I have not checked that. If you do a SSE version, even of Fruit Rebel should the compiler then not either replace those functions (count bits by an algorithm ) if they are AVx or else give an error? But I don't think it did when I once tried to make an SSE version I believe can't remember for certain if I did make one, anyway I don't think Ed mentioned it at least not here?
Edit: Oh I think that Fruit already does count bits by an algorithm, BIT_COUNT not by calling some hardware popcount instruction? Not much has changed in pawn.h and pawn.cpp in Toga so that probably would not be cause of an error in Toga but not in Growing Fruit or cause of error in SSE but not AVX
Trying to make a SSE compile with Visual Studio 2022:
So these options seem to be also deprecated already in Visual Studio 2022, just as the below IA32 I think it was that I tried for Eric (Tibono) in another post for his Penryn...
y Feng [MSFT] Closed - Not a Bug ··· /arch:SSE and /arch:SSE2 are only available when you compile for the x86 platform.
Well, then I tried to make Win32 (this is for very old processors) instead of x64 but then there are errors aplenty, among which some popcounts (this is really the Rebel 15 code running in Ed's Rebel 14.1 solution):

Thanks, Ed. You tried, it did not work, you did what you can. Bugs would also explain the problems with the search, where Toga misses mates.
In the Netherlands you have plenty of small shops who sell quality refurbished PC's with 2-3 year guarantee. An example of the shop I have bought my stuff for more than 25 years.
You have a PC with AVX2, 6 cores for only 395 euro, 3 year guarantee. HP workstations are almost indestructible. Seems to me you must have something similar in your country. New price is factor 4-5.

I was going to wait a bit but before you know it people will send lawyers.... No hurry for my part. Can wait a few weeks. I dont think I can build Toga yet with Microsoft Visual C, at least only a very slow version. Fruit works much better, for some reason.
