'''Shallow Blue''',<br/>
an [[UCI]] compliant [[:Category:Open Source|open source chess engine]] by [[Rhys Rustad-Elliott]], written in [[Cpp|C++ 11]], and first released in 2017under the permissive [[Massachusetts Institute of Technology#License|MIT License]]. Shallow Blue lacks various standard [[Pruning|pruning]] and [[Reductions|reductions]] heuristics such as [[Null Move Pruning|null move pruning]] and [[Late Move Reductions|LMR]],
and can therefore considered as didactic engine with some prospects to improve.
