In this quiz, you will have five hands where your opponents have stopped in a partscore.
If you pass, it will be the end of the auction, and your opponents will play the contract, but it's not too late. You might want to balance, if your hand is fit to do so, to try and play a contract.
You should do it when you are short in the opponent's suit, and when they have a fit, because the odds are high that you will find a fit of your own.
Good luck.
