Since you are probably the person most familiar with chess960 on this site, are there any unusual situations that might come up that require more knowledge than just the basic rules of 960 castling? I was U.S. Open champion of chess 960 around 8 years ago and also gave a simul of chess 960, but I haven't played or watched more than perhaps fifty games so I'm no expert on the 960 positions. Let me know any subtle points I should explain to John Meyer in advance of the match, or if there are any ambiguities in the rules.
I think you are more expert than me with chess960. I'm a rubbish chess player actually

At Knight-Odds the difference is very large too:
Chess960 Knight-Odds against Fruit Komodo Contempt=50:
82.0%
Normal Chess Knight-Odds against Fruit: Komodo Contempt=50:
65.0%
Based on your results, we can estimate that elo differences between engines increase by a bit under 20% playing chess 960. If this applies to the upcoming match, it would make Komodo a modest favorite. But if chess 960 is especially difficult for humans (compared to comparable - level engines), perhaps 3 to 1 would be a good guess. We'll see.
I played more respectable Knight-Odds matches at 10''+0.1'':
Chess960 Knight-Odds against Fruit Komodo Contempt=50:
74.9%
Normal Chess Knight-Odds against Fruit: Komodo Contempt=50:
52.0%
Almost 200 ELO points gap difference, which might prove decisive, especially considering that 960 is hard for humans.
And Contempt=50 again came better than Contempt=100. All in all, in my view Komodo is the favorite now. About Contempt, I cannot really gauge what in would need to be against a human at LTC, I would go for 100 against the intention of the human to draw the games. Fruit doesn't use this intention. From the old matches, I was bothered that human was able to draw in the early middlegame because of the too low Contempt of Komodo.

Few mediocre moves by Meyer and Komodo might be able to stabilize the position.
I think a value of 100 (or even a bit more) is good for this match, even if 50 is better against an engine. For one thing, we want to avoid a rep draw if the handicap has been partially recovered.

I suppose castling is allowed
Starting positions will be chosen at random about five miuntes before each game; John can be studying the initial position while I set up the computer and the broadcast. Castling will be according to standard chess960 rules. John volunteered that in the unlikely event that normal chess is chosen by lot we'll draw lots again, as it would defeat the purpose of the test.

Lot of 518 is the starting position of classical chess. That's 1/960 or 1‰ chance.
