Talking about opponents' moves in general seems like kibitzing to me. And kibitzing just shouldn't be done.The line between "Hey Player 2, if you do X, I'll do Y" and "Hey Player 2, Player 3 really wants Act4 this round, you should get in front of them and take Act4 right now" really is not that great.
I don't think you should be talking about what your opponents can or should be doing, period. Let people figure things out for themselves.
