Jordan / Truscott 2NT (Two No-Trump)

Jordan 2NT (aka Truscott 2NT) shows an artificial limit raise or better by responder. It is used when partner opens 1-major and the opponents make a takeout double:

Opener     1

RHO Dbl

Responder     2NT*

In this auction, 2NT shows 4 spades and 10+ points. This frees up the jump raise of 3 to be a weak, preemptive raise (4 spades, 5-9 points).

With a natural 2NT bid (balanced shape, 10-12 points), responder simply redoubles over the opponent's double.

Opener's second bid is natural, barring any other agreed conventions. Note that opener's rebids are the same if the opponents pass or bid over 2NT.

Rebid	Meaning
3	13+ points. Forcing to at least 3-major. Depending on partnership agreement, it shows one of the following types of club suits: Natural (by default), showing 4+ clubs. Help Suit Game Try (showing 3-4 clubs) asking responder to bid game with strong clubs. Short Suit Game Try (showing a singleton) asking responder to bid game if he does not have wasted club values.
3	13+ points. Forcing to at least 3-major. Depending on partnership agreement, it shows one of the following types of diamond suits: Natural (by default), showing 4+ diamonds. Help Suit Game Try (showing 3-4 diamonds) asking responder to bid game with strong diamonds. Short Suit Game Try (showing a singleton) asking responder to bid game if he does not have wasted diamond values.
3	If opener originally bid 1, then this is a signoff. If opener originally bid 1, then this is natural, showing 13+ points (game-invitational values). Forcing for one round.
3	If opener originally bid 1, then this is a signoff. If opener originally bid 1, then this is natural, showing a good 14+ points and 4+ spades. Since opener has bypassed 3, this is forcing to game.

• If opener has signed off in 3/, then responder can pass with a minimum.

• If opener has bid a new suit, responder can sign off in 3/ with 10-12 points. With 12+ points but no slam interest, responder can sign off in 4/.
