"Also annoying are Horde Chess players who studiously avoid playing Black. It's hard to know what their high rankings signify, if they result from having played White 95% of the time."

   Yes i agree, Horde chess is a game i love to play. I  enjoy playing black but won't play with black all the time. There is a simple solution to fixing this problem. You should have Teh black pawns start at an even more advanced position. Make white earn the win. Even the Bishop pawns one step cloer to whites pieces i feel will make the difference.
