User summary: ダブルピックス (Daburu Pikkusu) is the risk-taking card game Double Picks. Each turn, you reveal a card from the deck, and when you reveal the same card as one of the cards revealed so far, you must take all of them. Instead of revealing a card, you may take the last card revealed. Cards are numbered 1-9, and there are more cards with higher values than those with lower values. Cards with lower values are colored blue and are counted as one negative point each. Other cards are red and counted as negative points equal to their face value. You should consider the risk of taking negative points while making your decisions.
