The 3 other big chess libraries that I know of in C++ are:
-
Pros:
- relatively fast, see PERFT Comparison
Cons:
- lacks documentation and utility functionality, also no support for Chess960.
- not very active anymore
-
Pros:
- Header and source file split, leading to faster compilation times.
- Position compression
Cons:
- Rather slow, see PERFT Comparison
- Lacks documentation
- No support for Chess960
-
Pros:
- Modern C++ (and relatively active)
- Header Only
Cons:
- No documentation
- Early Version (after 4 years)
- No support for Chess960 (I think)
