Re: KnightX 4.7 engine released
one of my favorite GM level test engines when playing against P5 (or other strong engine)
with my gambit book. Example (for a change not posted in the beauty contest
thread, below); an awesome novelty at move 5, and KNgtX47 this time didn't
blunder at a critical point, but played a weak positional move 9...Qc7?!
and from then on it went downhill (16...Rxf5 also was a weak move).
