In this bidding quiz, we will be looking at the first response to an opening bid of 1♥ or 1♠.
When partner opens 1♥ or 1♠, you can give a single raise with 3-card support. Playing standard methods, a double raise (1♥-3♥) shows a stronger hand (around 10-11 HCPs) and 4-card support. A game raise (1♥-4♥) is partly pre-emptive. It suggests a shapely hand of around 7-10 HCPs, often with 5-card support.
Many players like to use a Jacoby 2NT response when they have at least 4-card support and a game-going hand. (Look it up on the internet if this is an unfamiliar idea.)
