Description
---------------
SCP 1.0d (winboard version) by John Stanback
The original program and src by John Stanback was released in 1993.
This program served as the basis for the original 'GnuChess' engine.
Initial (too buggy & unstable) release with winboard support (1.0b) was
withdrawn about 8 months ago. Re-released now with many bugfixes.
* numerous bugfixes (castling - promotion - time control )
* winboard support improved (resign - draw offer - ics added).
* opening book expanded with many more openings.
*NOTE - only tournament time control (x moves in x minutes)
implemented currently.
