Legalities

Actually, that is legal. Jon and I talked about this a couple of weeks ago. It is okay to favor one group or another by countering someone else's point increase or decrease. What's not allowed is to undo the previous move by simply reversing the points. In chess, when a piece is simply moved back and forth more than three times in successive turns, it results in a stalemate, regardless of the players' positions. What I understand is that we want to avoid the appearance of stalemate by not allowing even one move to be atomically undone. Atomically simply means a series of steps carried out as if it were one step.

Anyhow, that's my $.02.
