3 - This is the same hand as Question 7, but now you must bid 3 as partner's maximum could be 19 HCP.

Explain in your own words the difference between a 1NT opening bid and a 1 opening bid.

1 promises anywhere between 12-19 HCP. It also could be any shape. All you know is that there are at least 4 hearts.

1NT is a balanced hand with 12-14 HCP and is much more specific.


Why do you always pass as responder after partner’s 1NT opening, when you have a balanced hand and 10 HCP?
Because 1NT has 14 HCP at the most so there cannot be enough for game.
