I think Mats' thought is that his modifications to the Zillions rule file, which make Zillions' openings more akin to what a normal opening looks like (more pawn movement, less queen movement), while possibly not actually improving Zillions' pay, results in more aesthetically pleasing games.

Aesthetics aside, that leads to an interesting question: Is it possible to make a Zillions .zrf file that noticeably improves Zillions' pay ('improve' being defined as having more wins) compared to a Zillions rule file that simply implements the rules of the games, leaving it up to Zillions to come up with the best move.

It's a good question, and one I would like to see answered in the 2010 Schoolbook tournament.

In the meantime, I'm slowly but surely building up a Schoolbook opening book. Last night, I ran ChessV all night doing a 12-ply PV evaluation of all of Black's replies to 1. c3. ChessV decided there are really two reasonable replies: 1. ... Ng6 (PV: +29) and 1. ... e5 (PV: +29). The other move that looks reasonable to me, 1. ... e6 (followed by 2. ... f5 to hinder White's control of this central diagonal) was #5 on ChessV's list (after 1. ... f6 and 1. ... d6) with a PV of -23.
