Nothingness: Pente has the same problem. Player 1 has an advantage. It's not a big deal between average players, but with two masters, P1 ill almost always win. I usually post two-game matches when I post new games. This negates the edge. I end up with a lot of splits, and I only earn (lose) BKR points for one win (loss), when I win (lose) both but that doesn't bother me. You could do the same with the games you mention.
