Myrddin,
a Chess Engine Communication Protocol aka WinBoard compliant chess engine by John Merlino. Myrddin started its life in 2009 as a 0x88 engine with rudimentary evaluation based on material and piece-square tables [2] , and was converted to bitboards in 2012 with v0.86. Search is basically alpha-beta with generally conservative extensions and reductions. Myrddin's SEE implementation is based on pseudo-code by Andres Valverde [3].
