Another great ploy, if you set it up right, is to extort chips out of other players. If you take the 34 card, for example, then the 35 (the highest card in the deck) won’t hurt you at all because it comes right after 34. However, it’s guaranteed to give any other player 35 points. So you can try to squeeze the other players as much as possible before taking the card.
Especially if you can squeeze 34 chips out of them
