If there were the same number of players in the section, pawns and knights would need twice as many open game slots to join the tournament. But think of it this way - what if Fencer introduced tournaments with 2 games against each opponent? People wouldn't complain, even though they would now if it was changed to that. Besides, Fencer said he was going to introduce more formats for tournaments later. I'm not sure how high on his TODO list it is though :-)
