Encouraged by Mr Duke's comment, I decided to play against my self a few games (for the lack of otb opps.)
The Conclusion I got to is that the game is seriously imbalanced. Pawns are very powerful (since they're nearly invincible, and can only be attacked from two squares,) and still you have eight of them. It's also difficult to checkmate the King, since it is very limited in movement.
My impression is that Betza finds this only interesting in a 'freezing' context, since he didn't include it on a page of its own. Mind you, the page's name is gorgon.html
If anyone (other than George Duke, who already endorses it) would provide his analysis for the game, or a chess program that plays it.
I will look into three pieces endgames, maybe I will come up with some ideas. Until then, I don't like this variant the way it stands.
