It occurred to me that the Nutters are unique amongst Betza's armies in their forward-backward asymmetry. I wonder if this could have an unexpected effect on the outcome of self-play games of engines with an evaluation that is not highly tuned. In a random mover Nutter pieces would tend to diffuse forward. Perhaps this makes the nutters a bit more aggressive than the others, which would benefit them if the others are not aggressive enough. Perhaps the others would benefit from a piece-square table with a larger forward-gradient, while the Nutters automatically play like they have one.
Good observations as always. ChessV has a more sophisticated evaluation than FairyMax but it is certainly not "highly tuned." I can definitely re-run the FF vs. NN test with the forwardness component of the FIDE's PST increased. I'll kick that off and see how much it affects the results. The test will take a few days to complete...
