That isn't a very easy question to answer. For "best game" several come to mind: 1. The game where Cray Blitz won the 1983 WCCC in the final round by defeating Belle. 2. The game where Cray Blitz won the 1986 WCCC in the final round by defeating HiTech, the pre-tournament shoo-in to win. 3. We had a match on chess.net a couple of years ago with 4 computers and 4 GM players (Christiansen, Yasser, Roman and I don't remember the 4th). In one game Crafty reached an opposite bishop ending that I was afraid was going to be a draw (crafty was a pawn up). It won that game and two GMs commented that during that game, it played as well as a human top-10 player. As far as heart-crushing defeats, the game that most stands out is the game we lost to deep thought (Cray Blitz) in Orlando Florida at the 1987 or 1988 ACM event. We were winning, and had found a crushing move, but due to some never-before-seen parallel search bug, we failed high on a "lemon" and played it and lost outright. We re-ran that position hundreds of times and it always played the right move. Later when we moved to a faster machine with more processors, we discovered it would fail frequently and I finally found and fixed the bug. several years after it was first seen.
