1NT = 1RF, having one of many types of hands, and 5-11 hcp.
2§ = May show a 3-card suit.
2NT = Balanced hand, 10-11 hcp. 2© could be
rebid on as little as 5 hcp. 3© is invitational
allright, but shows a 6-card suit.
The forcing 1NT-response brings NS to the only makeable game. If North upgrades and opens
1NT, his side will get to 4©, which can be set
by 2 tricks, once East finds the obvious §-switch.
The NS-pairs that don't treat 2 over 1 as a game force, will reach 4© via 1©-2©-3©-4© or 1©-2©-4©, the
style advocated by former world champions Enri Leufkens and Berry Westra (Westra, Bieden met Berry, vol. 3, p. 120).

3§ = Forcing game. South upgrades his
excellent 11-count. He prefers not to raise on 3-card support.
3¨ = Natural. The cuebid has not fixed the
tumps suit yet.
4¨ = Designates diamonds as tumps. A slam
usually plays better in the 4-4 fit, so that the 5-3 fit can be used for discards.
4NT = RKCB.
5© = 2 or 5 aces without queen of trumps.
6¨ = Grand slams that require at least a
succesful finesse in trumps, are very unprofitable in the long run.

3§ = Natural and forcing game, the so-called
high reverse. East upgrades his
11-count again. He prefers not to raise on 3-card support, and East may not get a second
chance to show his good clubs.
Dbl = Shows 3-card §-support.
3© = 3+ ©-support,
designates hearts as trumps.
3ª = 1st or 2nd round control of spades.
4¨ = 1st or 2nd round control of diamonds,
denies §-control.
4NT = RKCB.
5§ = 1 or 4out of 5 aces (1403-variation).
5¨ = Asking for queen of trumps. East will
respond 5© without that key card, allowing West
to stay at the 5-level.
Dbl = Calling for a ¨-lead.
Rdb = Announces ©Q and ¨K, or, ©Q, ªK and
§K. Owing to North's double, East does not need
to bypass 5©.
We use Truscott 2NT to show limit raise or better with 3+ support, when RHO doubles for
takeout. Boards 3 and 4 also make a strong case for Truscott 2NT in situations, where RHO
overcalls in a suit at the 1- or 2-level. The jump cue can often be used to distinguish
between 3- and 4+ support. The simple cue can still be used to search for the best fit, or
to aim at game in Notrump.
