I think exactly what I said previously.  Jeroen chose to have it play 1. d4.

There _must_ be a reason.  I assume it has to do with results with e4 vs
d4 that he has seen.  I don't assume it was to make sjeng have a worse
result.  Otherwise wouldn't GCP be the one that was complaining and making
excuses here?  He hasn't said a word about the book.  I find it hard to believe
that Jeroen would even _consider_ doing such a thing, much less actually doing
it.

You are the only one speculating.  Jeroen is the only one that knows what
went on in the opening book preparation.  His explanation seems rational and
honest.  Yours seems speculative and hurtful.

That he thought that 1. d4 was better for Sjeng.

It doesn't show, based on the amount of time you spend accusing others of
misdeeds, vs the amount of time you spend trying to fix your program's
shortcomings.

You spend way more time knocking others than is reasonable.
