Protej, a WinBoard compliant chess engine by Alex Brunetti, written in Delphi and Assembly. Protej applies rotated bitboards - its search evolved to iterative deepening aspiration search with NegaScout alpha-beta, null move pruning with R == 3, transposition table, and basic search extensions and reductions. The quiescence search ignores losing captures, thanks to a fast SEE implementation. So far, Protej played the CCT9, CCT10, WCRCC 2014 online, and CIPS 2007, CCC 2008, and CCC 2009 over the board.
