 * Home * Engines * Defenchess**

a UCI compliant open source chess engine by Can Cetin and Dogac Eldenk, written in C++ and licensed under the GPL 3. Formerly dubbed **SCTR** released in September 2017, it was renamed in advance to its participation of the 4th division in TCEC Season 11. As a surprise, the newcomer convincingly won the TCEC Season 11 4th division. During the TCEC Season 11, 3rd division, the Defenchess [|Bitbucket] link lost power and the project was apparently retreated.
