Hello Dmitry,

Engine was created from scratch. It was written at C++0x and uses classes, templates, stl (not in time critical parts of code), lambda expressions. Move generator and board presentation uses bitboards. Quazar uses standart techniques (iterative deepening, alpha-beta, PVS,transposition table, killer moves, history heuristic,quiescence search,null move, futility pruning, magic bitboards). It uses very simplified evalution function (calculated only material, PST, pieces mobility, king pawn shelter) and search therefore play relative weak.
