Requiem for Ernst Jandl [1]

a Chess Engine Communication Protocol aka WinBoard protocol 2 compliant chess engine by Severi Salminen, written in C with some x86 assembly routines, first released in December 2001 [2]. As bitboard engine, it uses rotated bitboards to calculate sliding piece attacks, and otherwise applies PVS alpha-beta with null move pruning, mate threat extensions, futility pruning, and SEE inside an iterative deepening framework without aspiration windows [3]. Requem has a simple evaluation function supported by a pawn hash table, and has some sense of pawn islands. It is not aware of repetitions [4], and lacks a main transposition table [5].
