Hi all,

I’m back from my Cruise. Instead of reporting on New Engines or Updates in the STS thread, I thought I’d start a new Thread.

Arasan v20.3.0-19-g33972b8 (levels)
Ethereal 8.49
Nemorino
Rodent III 0.230 (personalities, but I couldn’t select them?)
SCTR 1.1
Shallow Blue 1.0.4
Stockfish 8 261117 (levels)
SugaR S_XPrO 261117 x32: (Stockfish derived, levels)

Hi all,

StingSF9 (Stockfish derived, levels)

Yesterday’s Rodent III problem was my own doing, I forgot to add the personalities 😡

The latest Andscacs version 0.921 is open source for this version only, however I’ve been unable to Compile it yet, it anyone has, please let me know.

It looks as though we are close to a Stockfish 9 release ..

There are 2 new Engines Scorpio 2.7.9 & Tucano 7.00 which I haven’t managed to compile yet, any help would be appreciated.

These aren't UCI engines, are they?

Hi DJ,

Yes you’re quite right, they are XB, I’ll forget these. The new versions of these 2 Engines are not listed in Computer-Chess Wiki yet, I should have checked earlier Versions for UCI compatibility.

However, although I’ve successfully compiled 33 different Engines and tried them on PicoChess, I’m still having problems compiling these 5 UCI Engines:

Amoeba, Andscacs, Demolito, DragonTooth & Embla. Can you help? I can point you at the source if required.


Cheers,

Al.

Hi Al,

There is a binary for Dragontooth 0.1 (though not for 0.2):

I have given up on Amoeba. The author does not want to spend too much time on Raspberry Pi support and, instead, refers to this old binary:

In order to compile Embla you need to perform these steps:
(1) sudo apt-get install libreadline-dev
(2) download and unzip the .zip archive from GitHub (https://github.com/flok99/Embla/archive/master.zip)
(3) remove the first line of IO_xboard.cpp
(4) make
Note: the engine identifies itself as 'Emblatrunk'.

Andscacs and Demolito are throwing lots of gcc warnings and errors, too many for me to investigate right now.

Cheers,
DJ

Hi DJ,

I’d already found the binary for DragonTooth 1.0 and had run a STS test a while back. It should compile using go, but I haven’t managed it yet. Zurichess Nidwalden compiles fine using go.

I’d also managed to compile Amoeba under Jessie and had tested v2.4.1.l32a, but have trouble with Stretch. I’ve seen the authors comments on your raised issue.

Thanks very much for your help on Embla, I’m curious as to why I can’t use the GitHub version rather than the Zipped file, I see 4 small differences but they both compile fine.

Yes, Andscacs and Demolito throw out far too many error messages.


Thanks again,

Al.

For demolito i cant recommend it. The author is not too helpful and he doesnt want to correct any uci error's his engine has.
I changed the picochess source code to allow this engine to work, but i wont put demolito inside with such problems.
Thats a pity cause its a strong engine with uci960 support...but not my fault.

Hi all,

Snowy 0.1-9-g4b8604e-dirty (no levels)

The default compiler uses Clang++, I compiled with both Clang++ and C++ then ran an STS test against both versions:
Clang++ 1692, C++ 1682. This is for a high end Processor, so the Engine will be weaker on the RPi.

So I gave it a quick game on Fischer 5,3 with the book turned off. I don’t normally post my games, but I won easily.

I’m around 1650 ELO but weaker in quick games, here’s the result:

[Event "PicoChess game"]
[Site "Bermondsey, United Kingdom GB"]
[Date "2017.12.22"]
[Round "?"]
[White "Scally"]
[Black "Snowy 0.1-9-g4b8604e-dirty"]
[Result "1-0"]
[WhiteElo "1650"]
[BlackElo "1690"]
[Time "12:41:10"]

1. d4 Nf6 2. e3 e6 3. Bd3 Bb4+ 4. c3 Bd6 5. Nd2 O-O 6. Ngf3 Nc6 7. O-O e5 8. e4 exd4 9. cxd4 Nb4 10. Bb1 Be7 11. a3 Na6 12. Re1 d6 13. Nf1 Be6 14. Qd3 d5 15. e5 Ne4 16. Ng3 Rc8 17. Nxe4 dxe4 18. Qxe4 Re8 19. Qxh7+ Kf8 20. Qh8# 1-0

So Snowy is quit a weak engine, but maybe what some people want ...

Hi Al,
with which command / parameter did you complicate Sugar?

greetings
Wilhelm

Hi Wilhelm,

All you need to do is enter the following commands in a terminal:

My default directory is set as /home/pi
sudo git clone https://github.com/Zerbinati/SugaR
cd SugaR
cd source
sudo make clean
sudo make profile-build ARCH=armv7
This compile will take around 5 minutes, the resulting Engine will be called sugar

Assuming you get this far, I can talk you through how to add this to PicoChess should you not already know.


Cheers,

Al.

Hello Al,

Thanks for your information.

I had previously compiled with the command "make build ARCH=armv7. This results in a 369 kB file.
The very first start of Arena, the message "Could not open Cerebellum_Light.bin"
displayed. But only once. Sugar, however, began to calculate. Only I do not know if the engine is now weaker than normal. So I thought, I'll ask a pro.
Info: Arena on my Windows PC has access via ssh to the engines of my Pi2 and Pi3. To classify the game strength I run Engines-Tuniere.

After your instructions, I get a sugar file with the size of 358 kB. Here too I get the message "Could not open Cerebellum_Light.bin" at the very first start in Arena.

This message comes only once (as far as I can judge now).

At the moment a tournament is running, if it is through I will report again.

Merry Christmas
Wilhelm

Hi Al,


Thanks for all your engines update information.
Since I am relatively new to picochess (having a DGT PI) I would like to new if there is a link to the raspberry binaries of some of these additional engines as I don’t know how to compile and make these on my own (but I think I would know where to put them in order to use these engines)

Thanks for you help.

Dirk

Hi Al,

What about The Baron 3.42 (homepage) and Senpai 2.0 (homepage)? Do you have any experience with these engines?

I compiled both engines on my Pi. Senpai seems to work correctly with PicoChess. It supports Chess960 but unfortunately does not have levels.

I'm having difficulties getting The Baron to work. When adding it to PicoChess the build/engines.py script gives an error message.

Greetings,
DJ

Hi DJ,

I’ll have a look, I’m pretty sure I tried The Baron, I ignore any Engines that don’t work with PicoChess.
I missed Senpai, thanks for the links.

Horst is always looking for Chess960 support Engines.

Hi DJ,

I had tried The Baron 2 days ago, the files were still in my Documents App, so I had another go.
I couldn’t see any source so I tried the pre compiled Binary for the RPi. this failed when started in a terminal:

pi@picochess:~ $ ./baron342-rpi

The Baron
version 3.42, January 4th 2017
ARM version
Copyright (C) 2001-2017 ir. Richard L. Pijl

Evaluation Version: evalparam.20150829184642.h

Syzygy bases enabled

FATAL ERROR: Cannot read the english messages file


So I copied the english.lng file and tried again:


pi@picochess:~ $ ./baron342-rpi

The Baron
version 3.42, January 4th 2017
ARM version
Copyright (C) 2001-2017 ir. Richard L. Pijl

Syzygy bases enabled

Found 0 tablebases.

W[1]>

It needs input on the terminal and responds to e2e4 etc.

———

With Senpai, the source is available. I had to change 1 line see here:


< CXXFLAGS += -O2 -marm
---
> CXXFLAGS += -O2 -mpopcnt -mbmi2 -DBMI

This failed when compiling with clang++

however a g++ compile worked, but on trying to start the engine and typing UCI and go infinite, I get a segmentation fault:

Hi all,

Zevra 20180120

I finally managed to compile OpenTal 1.1 and it runs and responds to UCI commands, but it won’t build on PicoChess.
I also tried Senpai thanks to DJ, but get a Segmentation Fault.


Cheers,

Al.

Hi Al, can I ask you a question about engines on the Pi in general?

I’ve been playing about with my Pi and with the ‘now working’ screen (official 7” touch) and came across a version of Arena that runs on Rasbian. However unlike the other Linux builds it only comes with one engine. It has the ability to add more but I’m guessing that they might need to be especially compiled.... do they ? Can you help me here? I wonder if the PicoChess ones work! Have you run Arena on your Pi? it works well with the DGT board, in fact the perfect solution if you are looking for a “graphical” chess companion.

Cheers
Harry

Hi Harry,

Yes the PicoChess Engines + any others that compile on the RPi will work with Arena on your RPi.

I tried Arena when it was first available for Linux but it was buggy, so I stuck with SCID vs PC for my Engine tournaments, I should give Arena another try.

I’m lucky in that my DGT board is a Revelation II. This comes with 10 Engines built in, plus with the latest updates, 24 Retro Engines, it also has a Bluetooth mode which now supports 11 characters as per the DGT Pi Clock. I can also play any Windows Engine on it using the Revelation UCI Server and PicoChess now has Remote Engine where I can enjoy any Engine from any platform with the beauty of playing across a board not on a screen.


Cheers,

Al.

Hi all,

Thanks to our friends on the TalkChess Forum, OpenTal 1.1 now compiles and works on PicoChess, no Levels or UCI960 support I’m afraid.


Cheers,

Al.

Al do these engine updates you announce automatically update when PicoChess updates ?  if not how its best to update them.

Hi Harry,

The Engines I mention here are the latest updates of current Engines or brand new Engines that I search for, compile and will work on PicoChess. (I test them)

Some are Engines we are currently using, later releases of these will be added to PicoChess.

The others are possibilities that could be used on PicoChess.

Ultimately, Jürgen controls which Engines are used. They need to adhere to certain criteria like support levels or support certain UCI parameters like Ponder & Search Moves etc. Cinnamon was recently deleted because it didn’t support these UCI parameters.

We are always looking for new Engines, so I spend some of my spare time looking and posting here, knowing DJ and Jürgen are always monitoring.

I have posted my email address within this thread, if you are looking for certain Engines you want to try on Arena or elsewhere, please give me a shout.


Cheers,

Al.

Hi all,

I managed to sort out the small coding error that the Sugar author had done and left a message for them. They had refactored some code for Windows, but left the old variable in place for Linux.

This then compiled ok:

Hi all,

New Engine TeKi 1 no levels or uci960, apparently close to 2200 ELO on faster Windows systems. Other UCI options to be added in later versions.
It compiles and runs fine with no Makefile modifications.

I’m away until the 26th, see you then.

I’m hardly at the level of Uwe’s kind description of me ‘Engine Master’, but have reached the heights of ‘Competent Apprentice’ :d

With some gentle hints from Master Jürgen, I have finally managed to compile the new version of Arasan:
