If you fail to win the number of tricks you bid, you go bust, meaning you break, and you are penalised for the hand. The Turkish name Batak itself refers to sinking or getting stuck, which is exactly what happens when you cannot fulfil your promise. Falling even one trick short of your bid usually costs you, so bidding is a careful balance between ambition and safety. This risk is the heart of the game: bidding high can win big, but only if you actually capture the tricks. Opponents will often play specifically to stop the top bidder from reaching their number.
