Engines under 1600 ELO at CCRL for analysis

[Carlos777]

I'd like to know if there are any engines under 1600 ELO (at 40/4 CCRL) that I can use to analyze epd files. I have been trying some WB and UCI engines under Arena, but without success. If anybody knows, please point them out to me.

The problem with engines that weak is that they are often buggy. Any reasonable bug-free engine (besides highly experimental stuff) will be much stronger than that.

Why not just run a strong engine for very short time per position?

Have you tried Pigeon? I do not have a computer that I can use to test it, but from the source it looks like it can be used to analyze positions.

Hi Adam,

I tried it, but it did not work under Arena 3.5.1

PS: It analyzes the positions, but does not post any analysis until it reaches depth 8 (takes more than 30 - 40 seconds), so if I want to give 10 sec/pos won't find any solution.

I will test all the strongest engines, but I want to test also the weak ones. So far, the weakest (according to CCRL) working engine I found is ChessRikus 1.466 (1613)

Sorry for my ignorance, what you need the weak engine do to "analyze epd files"?

I just want to try some engines on known tests like the WAC, ECM, STS, etc. I'd like to know how the weak engines do in these tests.

I'm sure I could find a version of Ethereal from a ways back that is around 1600.

I'm also sure it would be loaded with bugs, and lack of full UCI / xboard support.

If you can't find anything else, I'll see if I can find something for you.

Bill Forster's TarraschToy engine - not in CCRL but strength is close to what you are looking for and analysis mode runs fine.

Pigeon binaries are here available:
https://github.com/StuartRiffle/pigeon/releases

Michael Byrne was not able to build a working Macintosh compile- too many errors.

It works on Arena 3.5.1 with Windows 7 SP1 64-bit - just download

Visual C++ Redistributable for Visual Studio 2012 Update 4

Spanish edition is here: https://www.microsoft.com/es-ES/downloa ... x?id=30679

Older engines cf. the French website http://lefouduroi.pagesperso-orange.fr/ ... ui/sui.htm

Best wishes,
