Ok, I think I have isolated the revision where the regression occurs. Not entirely sure yet, since I'm only 50 games into the test match and I still need to run the verification (the single revision befrore) after that, but indications are good:
Code:

Rank Name             Elo    +    - games score oppo. draws
   1 Sjaak 399       2179   10   10  4000   66%  2049   10%
   2 Sjaak 417       2143   22   22   834   61%  2049    9%
   3 Sjaak 467       2099   10   10  4000   56%  2049    9%
   4 Sjaak 437       2090   10   10  4000   55%  2049    8%
   5 Fairy-Max 4.8O  2049    6    6 12888   41%  2124    9%
   6 Sjaak 422       2041   86   86    54   49%  2049    6%

I know exactly what I changed in that revision, and reversing it will be easy (I removed an unsafe form of futility pruning which would assume that no qualising capture existed without testing that assumption). The only downside is that I also remember clearly why I made that change: it can backfire spectacularly.

EDIT: that does look like it accounts for a large chunk of the regression, but not all of it. There is one other non-cosmetic change in between, which is reducing checking moves with bad SEE. So this idea may not pay off in Gothic chess (possibly because sacrificing a minor to get an attack against the king is more likely to succeed with three heavy pieces). Interesting.
