Thompson, George Duke has played a few games of Omega Chess, one of them was against me.
Personally, I think Omega Chess is a good game in its own right. However, the endgame does play out like a prolonged and boring Chess ending. The existence of all those leapers (and the huge space between the two armies) makes pawn pushes somehow unnecessary, and pawns are the soul of chess.
I wonder though, what George Duke considers to be the 'best' decimal variant, (my bet is that he will say Rococo, but I would call it an Ultima variant, not a Chess variant.)
