Juggernaut 1.01:
This is a bug-fix version of the initial release

Fixes:

• Aspiration window bug that gave crazy high mate announcements
• PV bug that showed illegal moves (due to not setting the path length in the quiescent search when there were no captures)
• Fixed bug that ended search too soon when pondering at fixed time controls
• Added a extra "send info" string to stop FastChess yammering
• Added image to download cutesy of Jim Ablett

Core Features:

• Create a rock-solid Delphi chess engine, capable of playing ultra-fast games (tested at game in 0.5 sec + 0.05 sec increments)
• Multi-PV and multi-threaded capable — this is a first for me (Juggernaut is certainly the weakest multi-threaded engine, and one of the weakest chess960 engines)
• Supports all aspects of the UCI protocol including: UCI_CurrLine, UCI_Refutations
• Chess960 support
• Super basic search

Download here: Juggernaut 1.01 (estimated strength of 2150 ELO on the CCRL scale)
