harleyman, I don't know if this fits in with your question but, generally, when we say something plays "up", we mean that it doesn't get moved except to be played "straight up". For example, in today's game, the 4
plays up in the strict sense of the word. It gets moved directly to the Ace pile without moving it previously. In that case, some players like to say that it plays "straight up". However, the 3
"plays up" but FIRST it gets moved to the 4
so we wouldn't generally say that it "plays up". Saying that something "plays up" or "plays straight up" is to help other players save a move. Hope that makes sense !
