LittleThought,
a free UCI compatible chess engine by Nathan Thom, able to play Chess960. LittleThought uses a rotated bitboard based, fully incremental move generator, and applies a PVS based alpha-beta search with several tree shaping and pruning routines, such as singular extensions, late move reductions, and null move pruning, and 4-way probe transposition table with other smaller hash tables for caching calculations of pawns, materials, and evaluation. The killer- and history heuristic as well just in case IID improve move ordering. Up to 8 threads are supported for a YBWC based parallel search [1]. So far, LittleThought played the NC3 2006 Australasian National Computer Chess Championship.
