1. <\/strong>What a jump shift shows<\/h3>\n\n\n\n
<\/div>\n\n\n\n

Definition<\/strong><\/p>

Opener’s second suit is bid with a jump, at the 2- or 3-level depending on the sequence. This jump initiates a game-forcing sequence. It promises at least 19 HCP with 5-4 distribution but 17+ HCP with at least ten cards in the two suits.<\/p><\/blockquote>\n\n\n\n

Note:<\/strong> there is no natural jump-reverse bid. These jumps are conventional, showing a forcing raise with four cards in Responder’s major, called “Superforcing”. <\/p>\n\n\n\n

3♥️ is not a natural bid that we would make when wanting to show a 6-5 two-suiter. <\/p>\n\n\n\n

<\/div>\n\n\n\n

Remember<\/strong><\/p>

1) Jump shifts are forcing to game. They promise a minimum of 19 HCP with 5-4 distribution but only 17 HCP (or more) with nice distribution (at least ten cards in the two suits).
2) Opposite a reverse or a jump shift at the 2-level, Responder’s 3NT bid is very precise, balanced and in the 9-11 HCP range. But if the two-suiter is shown at the 3-level, there is no more space for 2NT(!) and a 3NT bid is therefore no longer so precise (Responder will dive in when he holds the fourth suit). <\/p><\/blockquote>\n\n\n\n

2. Responder’s action<\/strong><\/h3>\n\n\n\n
<\/div>\n\n\n\n

a) The jump shift was at the 2-level<\/strong><\/h4>\n\n\n\n
<\/div>\n\n\n\n

This is always a jump in a major. Here are some principles to remember. <\/p>\n\n\n\n
