Porucznik, a WinBoard compliant open source chess engine by Mariusz Rostek, written in C++. Porucznik is successor of Sierżant, the Sergeant advanced to a Poruchik or Lieutenant, notably due to remembering transpositions better due to a transposition table. Porucznik played the IOPCCC 2008 and the PCCC 2009 over the board.
