Cinnamon is a chess program for Windows, Linux, Mac OS, Android and Raspberry Pi, is a console-based chess engine for use with xboard, Arena, Tarrasch, Droidfish or any UCI-compatible GUI. Cinnamon is also a javascript library to play with chessboardjs or any js GUI.

Binaries are available here. All files are compiled statically, no further libraries are necessary.

cinnamon -perft [-d depth] [-c nCpu] [-h hash size (mb) [-F dump file]] [-Chess960] [-f "fen position"]

Setting -F and -h you can stop (Ctrl-c) and restart the perft process.

cinnamon -dtm-gtb -f "fen position" -p path

cinnamon -wdl-gtb -f "fen position" -p path

cinnamon -dtz-syzygy -f "fen position" -p path

cinnamon -wdl-syzygy -f "fen position" -p path

cinnamon -puzzle_epd -t K?K? example: cinnamon -puzzle_epd -t KRKP

Cinnamon requires C++11 or greater, use unique Makefile to compile for many architectures:

$ make


Makefile for cross-compile Linux/Windows/OSX/ARM/Javascript

make cinnamon64-modern-INTEL     > 64-bit optimized for modern Intel cpu
make cinnamon64-BMI2             > 64-bit optimized for Haswell Intel cpu
make cinnamon64-modern-AMD       > 64-bit optimized for modern Amd cpu
make cinnamon64-modern           > 64-bit with popcnt bsf sse3 support
make cinnamon64-generic          > Unspecified 64-bit
make cinnamon64-ARM              > Optimized for ARM cpu

make cinnamon32-modern           > 32-bit with sse support
make cinnamon32-generic          > Unspecified 32-bit
make cinnamon32-ARM              > Optimized for ARM cpu

make cinnamon-js                 > Javascript build

add:
 COMP=compiler                   > Use another compiler
 FULL_TEST=yes                   > Unit test (googletest)


g++ is the default compiler, add COMP=yourcompiler to use another compiler
 example: make cinnamon64-modern-INTEL COMP=clang++

Cinnamon is released under the GPLv3+ license.
