Thanks for the replies.

Lozza's pawn eval is too primitive. It was treating the doubled white passers as better than the slightly less advanced connected black passers.

If I hack things to only consider the first passer per file and reward connected passers, KG2 kicks in.

I found this by watching some test tourney games rather than tweak and wait. Lesson learned. Young engine. Watch it more.

I found I learn more about Crafty by watching it play games, as in the ACCA/CCT and HGM's monthly events. If you watch while the game is being played, you follow along and you will notice strange things here and there. A glitch on time usage, or whatever...
