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)
