Fizbo 1.4 winboard chess engine. New version 19.05.2015

Fizbo - winboard chess engine

Fizbo - homepage
Author - Youri Matiounine


Changes in version 1.4:

1. various small modifications to search and evaluation, resulting in approximately +30 ELO. 
2. engine can now change size of main transposition table on the fly, using Xboard protocol command "memory N". Size of TT is rounded to nearest power of 2. 
3. engine can now use 3-4-5 piece syzygy endgame bit-bases and table-bases. Path of syzygy tables can be passed to the engine using Xboard protocol command "egbpath TYPE PATH". On engine start-up it is also taken from environmental variables DTZDIR and WDLDIR, for DTZ and WDL tables respectively. 
4. parallel search is now more advanced, allowing multiple active split-points at the same time. This should improve performance on 8 and more CPU cores (sadly, performance on 4 cores is mostly unchanged, aside from increased strength of single core engine).
