An invaluable resource for any chess engine author is the excellent Chess Programming Wiki.
Without modified publicly released IvanHoe source code, and techniques from open source chess engines Crafty and Stockfish, IvanHoe 0B.09.18 would not nearly be as strong as it is now.
Edit: File re-uploaded, and am done with these...back to my shell.
Disclaimer: Actually, it's not really known if IvanHoe 0B.09.18 is any stronger than builds from unmodified source.
