Thank Mike and Bob, From Mike's game logs, I suspected my Crafty binary may cause the problem. Thus I have downloaded a new (actually it is three years old, not really new :? ) one from Mike's github - Crafty 25.2 for macOS. - It (Mike's binary) still displays the error message when I set cores to 1...

I still get some difficulties to make Crafty works smoothly. Crafty continues to puzzle me by some ambiguous messages. E.g., it doesn't like to set cores=1 by displaying an error. unable to open book file [./book.bin]. book is disabled unable to open book file [./books.bin]. Crafty v25.3 machine has...

Version 2.2! It supposes knockout (elimination) type and resumption last incomplete tournaments. There are also compiled binaries for Mac OS and Windows 64 bits you can quickly try. Now Bansia has almost all features/functions I have dreamed for: small, fast, portable, easy to use, easy to integrate...

I have just released version 2.0. The new feature is to auto-generate JSON files which are used to play tournaments. Instead of spending hours or even days to create manually parameters for command line and/or JSON files, now all are auto-generated in few minutes. Bellow is the introduction from the...

Wow, thank you. I have never written a makefile myself before

No, that would be a protocol violation. The engine is not allowed to respond to 'ping' before it fully processed all earlier commands, and that includes the 'force'. If 'force' would lead to printing of a move, (or a move would already have been printed when the 'force' was under way), that move wo...

The 'force' problem is endemic to CECP. In particular the initial specs did not specify whether an interrupted search should print a move or not. There will always be a race condition when sending 'force' to a thinking engine, as the think could end spontaneously, and the move it results in could t...

something wrong here. (1) Crafty ALWAYS sends "feature reuse=0". Just checked the source. I am using 3 versions of Crafty. The 1st one 23.6 I have downloaded from somewhere as a Mac OS binary. Yes, it sent "feature reuse=1". I will discard it. I downloaded two others in form of source code and comp...

I have just released version 1.5 to support WinBoard protocol and Polyglot opening books. So far all main/big chess functions are completed. For coming versions I have been working on a special function to auto generate Json files which are mainly used to configure engines and control tournaments. H...

I would grab the latest "official" crafty 25.2. Crafty 25 welcomes then "scares" me a bit by a warning when I enter command "new": unable to open book file [./book.bin]. book is disabled unable to open book file [./books.bin]. Crafty v25.3 machine has 8 processors White(1): new NOTICE: new command ...
